Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is an ultra-high temperature resistant core product, specially developed for high-temperature equipment, high-heat components and ultra-high temperature 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 modifiers and heat-stable fillers, featuring ultra-strong high temperature resistance, high temperature stable, no degradation, fine uniform closed-cell structure, good elasticity and high-temperature stability. It can be used long-term at 250℃ and short-term at 300℃, no brittle fracture, no performance degradation, effectively withstanding high heat, solving the problem of traditional foaming materials’ poor high temperature resistance in ultra-high temperature scenarios. Compatible with most of our high-temperature products, it is ideal for high-temperature components, high-heat buffers and ultra-high temperature scenarios.
