Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a low temperature resistant cryogenic stable core product, specially developed for cryogenic environments, low-temperature storage and cold-chain transportation scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with low-temperature resistant modifiers and cryogenic stabilizers, featuring ultra-low temperature resistance, cryogenic stability, fine uniform closed-cell structure, good elasticity and low-temperature performance retention. It can be used long-term at -100℃ and remains intact without brittle fracture at -120℃, no performance degradation in extreme low temperatures, effectively solving the problem of traditional foaming materials’ brittleness and performance loss in cryogenic scenarios. Compatible with most of our high-temperature and precision products, it is ideal for cryogenic components, low-temperature buffers and cold-chain protection scenarios.
