Skin-Friendly Jelly Gel Materials for Fever Cooling Patches and Medical Aesthetic Cold Pads

INTRODUCTION

Reusable cooling products, including fever cooling pads for children, post-laser aesthetic cold compresses and sports ice-gel packs, use a soft gel mass inside skin-safe film to store thermal energy and conform to forehead, face or body contours. Skin contact times can extend to hours, and facial aesthetic skin is freshly treated and sensitive, so the filling must be biocompatible, non-irritating and non-sensitizing. Hong Ye HY-9409 transparent addition-cure gel (penetration 150 plus or minus 30, density 0.96) is a well-proven filling: platinum-catalyzed, food and skin contact compliant with FDA/LFGB reports, odorless and non-staining, it stays durably soft and flexible at refrigerator and freezer-adjacent temperatures without hardening, delivering comfortable conformability that water-based gels lose after freeze cycles. Its non-tacky cured surface stays clean against skin and film.

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

GRADE SELECTION GUIDE

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.

CONCLUSION

The market for tank sealant jelly gel in this application area continues to expand as cleanroom construction, electronic encapsulation, automotive electrification, energy storage and consumer product manufacturing drive demand for reliable two-component addition-cure silicones. Hong Ye supports this growth with ISO 9001 certified production, 500-plus ton monthly capacity, complete compliance documentation and responsive application engineering. Buyers evaluating suppliers are advised to look beyond unit price and compare batch-to-batch consistency, documentation completeness, delivery stability and technical service responsiveness, because the cost of a sealing or potting failure - rework, downtime, certification delay or product recall - far exceeds the incremental cost of a quality gel. Choosing the correct grade for the channel, operating temperature and service environment, following the 1:1 mixing and pouring procedure and validating with a small trial batch all help secure a durable seal. Hong Ye welcomes sample requests and application enquiries; our engineers will recommend the HY-9400, HY-9405 or HY-9409 grade that matches the sealing or potting requirement and support qualification from first sample through volume production.
