Medical‑Grade Self‑Adhesive Silicone Gel
This two‑component transparent self‑adhesive silicone gel cures into self‑adhesive elastomer after mixing Part A & Part B at 1:1 weight ratio, no toxic by‑products released during vulcanization. It delivers excellent biocompatibility, non‑irritating and hypo‑allergenic performance for skin‑contact medical patch manufacturing. Complies with FDA, MSDS, SGS and SROHS requirements.
Key Features
- Two‑part 1:1 mixing ratio, transparent liquid before cure
- Self‑adhesive property after vulcanization, good stickiness to PC, PPABS, PVC and metal substrate
- Wide service temperature: -60℃ ~ 200℃, outstanding water, ozone and aging resistance
- Hypo‑allergenic, non‑irritating, verified via pharmacology, biological and clinical tests
- Available relative test documents upon customer request
Typical Applications
- Raw material for fever cooling patch, cold & cough patch, navel patch, infant IV dressing
- Scar repair dressing, wound plaster, eye patch, breast patch, ear protection pad, weight‑loss patch, motion‑sickness patch
- Base material for external‑use medical adhesive plaster
- Lamination onto plastic and metal surface for medical accessory
