Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is an ultra-low temperature resistant cold-resistant core product, specially developed for cryogenic equipment, low-temperature pipelines and ultra-low temperature 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 cold-resistant agents, featuring ultra-strong low temperature adaptability, no brittle fracture at ultra-low temperatures, fine uniform closed-cell structure, good elasticity and low-temperature stability. It can be used long-term at -100℃, no brittle fracture, no performance degradation, effectively adapting to cryogenic environments, solving the problem of traditional foaming materials’ brittleness in ultra-low temperature scenarios. Compatible with most of our cryogenic and low-temperature products, it is ideal for low-temperature resistant components, cold-resistant buffers and ultra-low temperature scenarios.
