Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a flame-retardant core product, specially developed for flame-retardant-required, high-temperature fire-prone and safety-critical environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with flame-retardant additives and fire-retardant stabilizers, featuring UL94 V0 grade flame retardancy, self-extinguishing within 10 seconds, no dripping, no toxic fumes, fine uniform closed-cell structure, good elasticity and flame-retardant stability. It effectively inhibits flame spread, reduces fire hazards, solves the problem of traditional foaming materials’ poor flame retardancy in safety-critical scenarios. Compatible with most of our electronic and high-temperature products, it is ideal for flame-retardant components, fire-proof buffers and safety-critical scenarios.
