Reusable silicone cooling products are replacing disposable hydrogel patches in family and clinic markets because they combine cooling comfort with years of reuse, and brands compete on skin-safety documentation for postpartum and pediatric use. Hong Ye supplies skin-contact transparent gel with biocompatibility data, ISO 10993 support and small-kit development packaging, helping Chinese manufacturers launch compliant reusable cooling products. The market favors suppliers who can provide skin-contact test reports and consistent clarity and softness across batches.

PRODUCT REQUIREMENTS
Cooling pad gel requires: skin biocompatibility (non-irritating, non-sensitizing); FDA/LFGB documentation; softness retained at fridge/freezer temperatures; non-staining, low-tack surface; transparent clean appearance; thermal conformity to body curves; and reusable long-term stability.
CORRESPONDING PRODUCT MODEL PARAMETERS
Recommended model: HY-9409 - Transparent low-tack grade for intimate apparel, personal-care and body-contact products requiring clarity and skin-safe materials
| Model | Color | Viscosity (mPa.s) | Operation Time (min) | Cure Time (hr) | Penetration (0.1mm) | Tack | Mix Ratio | Density (g/cm3) |
| HY-9409 | Transparent | 2200+/-400 | 20-40 | 4-6 | 150+/-30 | Low | 1:1 | 0.96 |
GRADE SELECTION GUIDE
| Model | Color | Penetration (0.1mm) | Tack | Typical Applications |
| HY-9400 | Blue | 200 | High | HEPA/ULPA filter gel channels, biosafety cabinet seals, applications requiring strong adhesion and re-sealability |
| HY-9405 | Blue | 170 | Medium | Electronic potting, sensor encapsulation, applications balancing softness and dimensional stability |
| HY-9409 | Transparent | 150 | Low | Transparent gel pads, intimate apparel, prosthetic devices, applications requiring visual clarity or easy repositioning |
FREQUENTLY ASKED QUESTIONS
Q: Does the gel stay soft after freezing?
A: Yes. Unlike water-based fillings that freeze hard, the silicone gel remains flexible at refrigerator and freezer-adjacent temperatures, keeping pads conformable.
Q: Is it safe on post-laser sensitive skin?
A: The gel is biocompatible, non-irritating and non-sensitizing with ISO 10993-capable documentation; the contact layer is the medical film, both meeting skin-contact standards.
Q: How long do reusable gel pads last?
A: Inside sealed film the gel does not dry out or degrade; products remain serviceable for years of refrigeration and reuse cycles.
QUALITY ASSURANCE & CERTIFICATION
Every batch of Hong Ye HY-94 series jelly gel is produced under ISO 9001 certified quality management in a dedicated silicone workshop, with incoming raw-material inspection, in-process mixing control and finished-product testing on every batch. Before release each lot is checked for viscosity, mix ratio, cure time, penetration, color and tack, and a Certificate of Analysis (COA) listing the actual measured values ships with every order. Standard grades carry RoHS 2.0 and REACH SVHC test reports; skin-contact and baby-care grades can be supplied with FDA 21 CFR 177.2600 and LFGB Section 30/31 reports and, on request, ISO 10993 biocompatibility testing; flame-retardant grades meet UL94 V-0. Food-contact, medical and export orders are supported by the corresponding compliance files for customer qualification. Hong Ye has manufactured and supplied jelly gel to contractors, filter builders and equipment makers in over 60 countries since 2005, with monthly capacity above 500 tons, batch traceability and multi-language documentation. Application engineers provide grade selection, sample evaluation, on-site or video pouring guidance and after-sales follow-up, and technical data sheets (TDS), safety data sheets (SDS) and test reports are available before order to support tender and audit processes.
