Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a UV-resistant weather aging-resistant core product, specially developed for outdoor, UV-exposed and harsh weather environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with UV absorbers and weather stabilizers, featuring strong UV resistance, excellent weather aging resistance, fine uniform closed-cell structure, good elasticity and aging stability. It has a UV transmittance of ≤5% at 280-400nm, can withstand long-term UV radiation and harsh weather (rain, snow, high temperature), no yellowing, no brittleness, no performance degradation, effectively solving the problem of traditional foaming materials’ easy aging in outdoor scenarios. Compatible with most of our industrial and outdoor products, it is ideal for outdoor components, UV-resistant buffers and harsh weather scenarios.
