When sourcing a reliable PCM neck cooler manufacturer in China, you face dozens of factories claiming the best cooling neck wrap wholesale deals. Sorting the real players from the middlemen takes time most buyers don’t have.
We’ve vetted ten leading Chinese suppliers based on production capacity, PCM cooling gel technology, certifications, and OEM/ODM flexibility. You’ll get side-by-side comparisons on pricing, lead times, and customization options, whether you’re importing in bulk, launching a private-label sports cooling line, or testing a small MOQ order. Our supplier selection checklist will save you from costly sourcing mistakes.
RU Entropy / PCMCOOL (Shanghai)
Founded in Shanghai in 2014, RU Entropy sells under the trademark PCMCOOL®. Their R&D shows in the numbers. They claim PCM temperature coverage from -50°C to 150°C, spanning normal paraffin, bio-based, and inorganic PCM types. That range is broader than most competitors on this list.
Product Line Breakdown
The paraffin-based PW series targets phase-change temps between 2°C and 28°C, with latent heat around 210–230 J/g. For lower temps, the HS product hits -26°C with 240 J/g latent heat. Solid specs if you’re comparing PCM cooling gel technology across suppliers.
The PCM neck cooler comes in three sizes: Small (178×168mm), Middle (185×174mm), and Large (191×190mm). Cooling duration ranges from 30 minutes to 3 hours, though direct sun at 40°C can cut that to 20–30 minutes. Phase-change temps run at 18°C, 21°C, 23°C, or 28°C depending on the application.
OEM/ODM Capabilities
RU Entropy offers OEM and ODM services and is recruiting global distribution partners. Their site emphasizes collaborative material selection and temperature matching. Useful if you’re integrating PCM cooling gel into a custom neck cooler rather than buying off-the-shelf.
Market Signals
Chinese-language pages claim their 3D S-series cooling vests earned “world-class” performance ratings from third-party labs and international users, plus positive feedback from military and police testers within two months of launch. Take those claims with reasonable skepticism. They’re unverified marketing copy, not independent audits.
No public pricing or MOQ appears on their site. Expect to negotiate based on material, phase-change temp, and packaging format.
Ice Bear / ICEBEAR TECH – Professional OEM/ODM Manufacturer of Personal Cooling Products
ICEBEAR TECH (Nanchang Ice Bear Heating & Cooling Home Products Co., Ltd.), located in Nanchang, Jiangxi Province, is a manufacturer specializing in the R&D and production of personal cooling and thermal management products. Compared to suppliers that only offer a single PCM Neck Cooler, ICEBEAR’s product range covers multiple cooling series, including PCM Cooling Vest, PCM Neck Cooler, Cooling Scarf, Fan Cooling Vest, and Water Cooling Vest, making it more suitable for B2B buyers who need to expand their complete cooling product line.
PCM Neck Cooler Customization Capabilities
ICEBEAR provides comprehensive OEM/ODM support for brand owners, distributors, and e-commerce clients. In addition to common logo, color, and packaging customization, it can also adjust product size, appearance, fabric, PCM formula, and phase change temperature according to project requirements, and provides branding services such as Pantone color matching, labeling, hangtags, and retail packaging.
This means customers can not only purchase existing styles but also develop their own Private Label PCM Neck Coolers based on their target market.
Prototyping and Mass Production
One of ICEBEAR’s advantages is its relatively complete manufacturing process, from sample development to mass production. For routine projects, rapid prototyping can be conducted according to customer needs. Mass production only begins after confirming the product structure, PCM performance, colors, and packaging, with multi-stage QC checks on materials, production processes, and finished products.
For B2B buyers, this model is particularly suitable for brands and distributors who need to test the market first before gradually scaling up orders.
Why should B2B buyers pay attention?
ICEBEAR is not simply a trading supplier selling cooling neck rings; it combines PCM technology, product development, and OEM/ODM manufacturing.
If the procurement target extends beyond a standard PCM Neck Cooler, and the goal is to further develop PCM Vests, Cooling Scarves, or other personal cooling products, then partnering with a manufacturer possessing a complete product line and R&D capabilities can reduce the procurement and quality management costs associated with finding separate suppliers for different products.
For enterprise clients seeking PCM Neck Cooler manufacturers in China, ICEBEAR TECH is better suited to focus on needs such as product customization, private labeling, mass production, and long-term product line development, rather than simply comparing the lowest procurement price.
Yangzhou Holly International Co., Ltd.
This supplier is backed by Jiangsu Holly Group, founded in 1979, with reported annual import-export volume north of US$1.6 billion. That scale matters if you’re worried about a factory disappearing mid-order.
The Core Product
Their TPU/PCM Neck Cooling Ring uses a flexible PVC/TPU outer shell with PCM phase transition material stitched tightly inside. The listing calls out non-toxic, freeze-and-reuse construction, freezing naturally below 28°C. Cooling duration runs 90–120 minutes by their own spec sheet, though comparable PCM cooling gel technology in the same category claims 3–4 hours at 30°C and roughly 2 hours in hotter conditions. No official freeze-thaw cycle count is published, but rival reusable neck cooling wraps often advertise 10,000+ cycles as a benchmark worth asking about.
Pricing and MOQ
Numbers vary by platform. One listing shows MOQ 100 pcs at $0.88–1.38 each; another puts MOQ at 2,000 pcs for $0.8–1. Beyond the neck cooler, they also produce rubber hot water bottles, ice packs, and microwave heating pads.
Reach and Reliability
Main export markets span North America, Western Europe, Southeast Asia, and Africa. Website updates through August 2026 suggest active operations, not a dormant listing. Before ordering, request DSC test reports and CE/REACH/RoHS documentation to verify their PCM neck cooler claims.
Glacier Coolant Technology (Beijing) Co., Ltd.
This Beijing-based supplier plays in a different league than pure neck-cooler shops. Its core business is industrial coolants and heat-transfer fluids for chemicals, pharma, cold storage, HVAC, data centers, and laser cooling systems, with a temperature range from -110°C to 340°C. The PCM neck cooler is more of a consumer-facing offshoot, sold under model numbers GC-NC01/02/03 with custom logo options.
Specs Worth Checking
The neck ring uses medical-grade TPU + PCM gel, measures 18×12×2cm, and weighs 125g. It’s rated for 3–4 hours of cooling, dropping to roughly 2 hours past 38°C. The standout spec is 10,000+ freeze-thaw cycles, with skin-contact temps held under 28°C and a phase-change point around 18°C. Freezing takes 20–25 minutes in a standard fridge, or 10–15 minutes in ice water. A 30–40 second zap at 600W in the microwave resets it for reuse.
Where the Value Is
No public pricing appears for this SKU. Expect mid-to-upper pricing because of the medical-grade materials and cycle count. Ask about MOQ, FOB tiers at 1k/5k/10k units, and whether CE/RoHS/REACH documentation exists — none of that is listed publicly, so ask before you commit to a PO.
Ningbo Thermal New Energy Technology Co., Ltd.
This company’s strength is material science. Based at RM 8002, No 2357 Tiantong South Road, Yinzhou District, Ningbo, they build PCM from the molecule up.
Four Proprietary PCM Types
They’ve developed bio-based PCM in four categories: SL-PCMs (pure PCMs), HC-PCMs (high thermal conductivity PCMs), ME-PCMs (molecular microencapsulated PCMs), and flexible polymer-based PCMs. Monthly output tops 100 tons. That capacity feeds cold chain packaging, HVAC, electronics, apparel, automotive, construction, and solar systems.
The Wearable Gap
Their public product pages confirm PCM use in textiles, including apparel and beddings. But there’s no dedicated outdoor neck-cooler spec sheet showing weight, phase-change temperature, or duration. Their microencapsulated and flexible polymer PCM lines fit wearable cooling gear, but you’ll need to push for numbers.
Megacoolpro
Hangzhou Yingqian runs the Megacoolpro brand. Its main SKU is the Detachable PCM Outdoor Neck Cooler from the PCM Sugar Cube series. The velcro attachment lets you strip it down and reposition it.
What Sets This PCM Neck Cooler Apart
You can wear it on your neck, wrist, or knee — three use cases, one unit. The square compartments keep cooling distributed across the pad instead of pooling in one spot. No ice-burn, no wet condensation dripping down your shirt. It’s built for repeated use in heatstroke prevention, not just a single cool-down session.
Specs and Materials
The neck ring uses a TPU and PCM build with a 26°C phase-change setpoint. Cooling lasts 1.5–2 hours for the ring version. A related cooling headband stretches to 1.5–3 hours depending on conditions. You freeze it, wear it, and refreeze it. No batteries, no fans.
Sourcing Status
Megacoolpro’s site states plainly: “We are a factory and trading company at the same time.” That’s a hybrid setup worth confirming during due diligence instead of taking it as a straightforward factory-direct claim.
Customization
Custom colors are available in white, black, or client-specified shades. No public MOQ or sample lead time is listed. Industry norms for this category run 100–500 pcs MOQ, 7–15 days for samples, and 15–30 days for mass production. Confirm those numbers directly before placing a PO.
Target buyers include outdoor workers, commuters, and sports users who want fatigue relief and summer heat protection.
Chengdu Cryo-Push Medical Technology Co., Ltd.
A medical device background sets this manufacturer apart from the pack. Founded in 2012 in Wenjiang District, Chengdu, Sichuan, Cryo-Push operates 11 product lines covering cold compression therapy systems, heat & cold therapy machines, DVT compression devices, and waterproof cast covers. Roughly 100+ staff generate about ¥50 million in annual sales, and the company operates as a Manufacturer/Factory with OEM/ODM support.
Certifications for Medical-Grade Sourcing
The FDA database lists Cryo-Push under registration number 3011491271, tagged as a Manufacture Medical Device entity at their Wenjiang factory address. Their site claims FDA-cleared and CE-certified status, backed by ISO 13485:2016 quality systems (some platforms also list ISO 9001). As of 2026, they’re still appearing as an applicant in 510(k) filings, meaning their regulatory pathway remains active.
Two Products, Two Use Cases
Their neck cooling tube (model TWB1-1801-S) delivers roughly 90-120 minutes of comfort at 18°C, fits necks under 28cm, and weighs about 100g. This is for short-duration heat exposure, personal use, or gifting scenarios.
Their PCM cooling vest targets a different buyer entirely. It covers the torso for sustained cooling, built for outdoor labor, sports teams, security patrols, and logistics workers who need heat relief that lasts longer than a neck wrap can offer.
Before You Order
No public MOQ or pricing appears on their listings. Industry norms for this category run 10-100 pcs for samples, 100-500 pcs for standard OEM runs, with pricing shifting based on logo customization, PCM formula, and fabric weight. Request FOB/EXW quotes, sample costs, and confirm which specific SKUs carry valid CE/FDA documentation — the “Medical Technology” name alone doesn’t guarantee every product in the catalog meets that bar.
CGS Industria
Something doesn’t quite add up with this one. CGS Industria shows up on Alibaba as “CGS INDUSTRIA CO., LTD.,” tied to Ho Chi Minh, Vietnam — yet other marketplace subpages list it under different product categories with no clear entity match.
Mixed Signals on What They Make
One listing ties them to seats and industrial seating accessories. Another shows cookware. A third points to microfiber cooling towels. That’s either a trading company juggling categories or three separate businesses sharing a name — no way to tell from public data alone.
Pricing Across the Board
-
Cooling towels: MOQ 50 pcs, $1.80–$3.50, 7–10 days
No PCM Confirmation Yet
Nothing in the public record confirms non-woven fabric + PCM as a current product line. If you’re sourcing a PCM neck cooler specifically, treat CGS Industria as unverified for that material stack. Request business license verification, factory floor area, and test reports before sending a deposit.
Ganzhou Sanmei
Ganzhou Sanmei Industry And Trade Co., Ltd. runs its factory out of 308 Binjiang Road, Lianjiang town, Xingguo County, in Ganzhou, Jiangxi. It suits small-batch buyers. The product lineup covers PCM neck rings, cooling tubes, gel packs, and hot-cold compress ice packs. They use phase-change material instead of basic water gel, which gives longer cooling duration.
Numbers That Matter for Sourcing
MOQ varies by product. One PCM neck ring order starts at 100 pcs, while a related cooling-tube listing requires 500 pcs minimum. Pricing spans US$1–US$5 per unit depending on which product and order size you’re comparing. Lead times run 7–12 days, with sample delivery reported at 5 days or less on some listings. One marketplace profile also shows 100% on-time delivery and average response times under 2 hours.
Customization and Compliance
Custom sizing shows up on gel-product listings, alongside typical color, logo, and packaging changes. No fixed custom MOQ is published, so confirm that directly. For compliance, a related hot-cold compress gel ice pack from this manufacturer carries a Class I (not sterile) classification, with document validity through 08.01.2029. That’s useful if you’re vetting this China cooling gear supplier for regulatory paperwork before placing a PO.
This setup fits Amazon and cross-border sellers testing seasonal cooling neck rings or gel-pack SKUs without committing to large inventory risk. If your project needs audited thermal lab reports or a locked custom-brand MOQ upfront, push for that documentation before ordering.
Shanghai Bingfan
Twelve years on Alibaba builds a reputation. Shanghai Bingfan Industrial Co., Ltd. has built theirs around a Japan-style TPU + PCM ice ring that’s become one of its best-selling SKUs. The neck cooling tube comes in three sizes: S (13×15cm), M (17.5×15cm), and L (20.5×17.5cm). Each weighs around 110g, with micro-PCM and elastic fabric handling the cooling.
Cooling Performance and Prep
Duration varies by listing. Some pages claim 60–200 minutes depending on ambient conditions; others state a flat 4 hours. Pre-cooling takes 2–4 hours in a freezer or refrigerator before use, and then you get a reusable cooling neck wrap.
How to Choose a Reliable PCM Neck Cooler Supplier
Ten manufacturers on a list mean nothing if you don’t know what to ask them.
Match PCM type to real temperature data. Solid-liquid PCM clusters around 18°C, 21°C, 23°C, or 28°C transition points. Get the exact number, not vague “strong cooling” claims. Micro-encapsulated PCM runs 12–16°C and holds up better for repeated freeze-thaw cycles. PCM gel feels softer on skin but can stiffen below 20°C, so ask if the formula stays flexible at cold storage temps. Published cooling durations range from 1–3 hours to 6–10 hours depending on ambient conditions. Always separate “lab time” from “real wear time” when you ask.
Certifications need paper. ISO 9001:2015, CE, RoHS, REACH, MSDS, and FDA compliance are the baseline for export markets. For kids’ products, add EN 71. Request the scanned original, certificate number, issuing body, expiration date, and confirmation it covers the exact SKU you’re ordering.
OEM/ODM questions that matter. Ask about the logo method (silkscreen vs. heat transfer) and minimum line width, Pantone color matching tolerance, packaging customization (box print, blister, manual language), shape flexibility for neck-size variations, and whether they offer multiple phase-change temperature versions.
Test samples before committing. Run 20–50 freeze-thaw cycles checking for cracking or leakage. Do a leak test under pressure and drop conditions. Measure cooling duration at 25°C, 30°C, and 32°C separately. High-heat performance often falls short of marketing claims. Pull 3–5 samples from the same batch for consistency.
Before sending an RFQ, collect business license, certificate scans, third-party test reports, product spec sheet (size, weight, transition temp), and your OEM requirement sheet. A factory that can’t produce certificates, reports, and sample data together is a red flag, regardless of how polished their catalog looks.
Common Questions
What buyers need to know about sourcing a PCM neck cooler manufacturer.
What’s the real difference between a PCM neck cooler and a regular ice-gel scarf?
PCM cooling gel technology works by absorbing and releasing heat at a fixed transition point, usually 18°C or 28°C. It’s a steady, low-stimulation cool. Basic ice packs sit near 0°C. They feel colder in the first 20–45 minutes, then fade fast and often sweat condensation onto your collar. PCM wraps stay milder longer, typically 45–120 minutes depending on humidity and pre-cooling method, without the stinging cold sensation.
Can I get a custom neck cooler OEM run below 300 pieces?
Some factories will do it. But 300–500 pcs per style/color is the standard MOQ across this industry. Drop below that threshold and expect higher sample fees, fewer packaging choices, and a bumped unit price. Most buyers new to this category start with a 300–1,000 pcs trial order to validate fit, print quality, and lead time before scaling up.
How do I confirm a factory’s real production capacity?
Ask for their factory profile: floor space, headcount, annual output, export ratio. Request a video factory tour showing the sewing line, sample room, and QC station. Then push for shipping records from comparable orders. A small 300–1,000 pcs trial run remains the most reliable proof.
What payment and inspection terms reduce risk on a first PO?
Clarify FOB or CIF terms upfront so responsibility at the port is unambiguous. A 30% deposit with 70% balance before shipment is standard for new buyers. Insist on a pre-production sample. Then get an AQL inspection or third-party verification before the container loads.
Conclusion
The right PCM neck cooler manufacturer matches your order volume, budget, and customization needs to a factory that can actually deliver. From this list, MOQ and lead times vary widely across China’s top suppliers. Certifications separate the serious players from the rest. True OEM/ODM flexibility turns a one-off order into a long-term supply partnership.
If you’re sourcing cooling neck wrap wholesale for the 2026 season, don’t wait until peak demand hits to lock in a supplier. Lead times stretch fast when everyone’s chasing the same factories. Start by shortlisting 2-3 manufacturers from this guide, request samples, and compare their PCM cooling gel formulations firsthand.
