Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a flame-retardant UL94 V-0 grade core product, specially developed for flame-retardant, high-temperature fireproof and fire safety 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 agents and fireproof modifiers, featuring UL94 V-0 grade flame retardancy, self-extinguishing, fine uniform closed-cell structure, good elasticity and flame retardant stability. It is self-extinguishing within 10 seconds, no dripping, no flame spread, effectively preventing fire propagation, solving the problem of traditional foaming materials’ flammability in fire safety scenarios. Compatible with most of our fireproof and high-temperature products, it is ideal for flame-retardant components, fireproof buffers and fire safety scenarios.
