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, heat-exposed and high-heat scenarios. 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 fillers, featuring ultra-high temperature resistance, heat resistance, fine uniform closed-cell structure, good elasticity and high-temperature stability. It can maintain stable performance at 250℃ for long-term use and 300℃ for short-term use, no aging, no deformation, no performance degradation, effectively solving the problem of traditional foaming silicone’s poor high-temperature resistance. Compatible with most of our high-temperature and industrial products, it is ideal for high-temperature equipment, heat-processing and high-heat scenarios.
