Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high-tear-strength tear-resistant core product, specially developed for mechanical parts, wearable products and high-tear scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with tear-resistant fillers and strength modifiers, featuring ultra-high tear strength, no easy tearing, fine uniform closed-cell structure, good elasticity and tear stability. It has a tear strength of ≥25 kN/m, high structural strength, no easy tearing or breaking, effectively extending service life, solving the problem of traditional foaming materials’ poor tear resistance in high-tear scenarios. Compatible with most of our mechanical and wearable products, it is ideal for tear-resistant components, high-strength buffers and high-tear scenarios.
