Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a tear-resistant high tear strength core product, specially developed for high-stress, frequent bending and tear-prone environments. 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 anti-crack modifiers, featuring ultra-high tear strength, anti-tearing, fine uniform closed-cell structure, good elasticity and tear stability. It has a tear strength of ≥15 kN/m, no crack propagation, can withstand frequent bending and high stress, effectively solving the problem of traditional foaming materials’ poor tear resistance in high-stress scenarios. Compatible with most of our industrial and mechanical products, it is ideal for tear-resistant components, anti-crack buffers and high-stress scenarios.
