Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high temperature resistant thermal insulation core product, specially developed for high-temperature, thermal-insulation and high-heat insulation 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 additives and thermal insulation fillers, featuring ultra-high temperature resistance, effective thermal insulation, fine uniform closed-cell structure, good elasticity and high-temperature stability. It can be used long-term at 250℃ and short-term at 300℃, low thermal conductivity, effectively isolating high temperature and reducing heat transfer, solving the problem of traditional foaming materials’ poor high temperature resistance and thermal insulation. Compatible with most of our high-temperature and industrial products, it is ideal for high-temperature equipment, thermal insulation components and high-heat scenarios.
