Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a low-temperature flexible cryogenic-resistant core product, specially developed for cryogenic environments, low-temperature equipment and cold-chain 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 modifiers and cryogenic stabilizers, featuring excellent low-temperature flexibility, cryogenic resistance, fine uniform closed-cell structure, good elasticity and low-temperature stability. It remains flexible at -80℃, no brittle fracture, no performance degradation under extreme cold conditions, effectively solving the problem of traditional foaming materials’ brittleness in low-temperature scenarios. Compatible with most of our industrial and aerospace products, it is ideal for low-temperature components, cryogenic buffers and cold-chain protection scenarios.
