Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a ceramicization flame-retardant ultra-high temperature resistant core product, specially developed for ultra-high temperature, fire-safe and extreme environment scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with ceramicization modifiers and high-temperature resistant raw materials, featuring ceramicization at 500℃ to form a hard protective shell, which can effectively isolate flame and high temperature, prevent fire spread. It has ultra-high temperature resistance (long-term use at 300℃, transient resistance at 1600℃), UL94 V-0 grade flame retardancy, fine uniform closed-cell structure, good elasticity and high-temperature stability, effectively solving the problem of traditional foaming materials’ poor high-temperature resistance and easy burning in extreme high-temperature scenarios. Compatible with most of our high-temperature and industrial products, it is ideal for ultra-high temperature components, fire-safe protection and aerospace thermal insulation scenarios.
