Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high-temperature resistant core product, specially developed for high-temperature and thermal-shock environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with high-temperature resistant components, featuring ultra-high temperature resistance, thermal-shock resistance, fine uniform closed-cell structure, good elasticity and high-temperature stability. It can withstand long-term use at 250℃, short-term exposure to 300℃, and resist rapid temperature changes (thermal shock), no cracking, no deformation, no performance degradation, effectively protecting high-temperature equipment and components. Compatible with most of our high-temperature products, it is ideal for high-temperature industrial, automotive and aerospace scenarios.
