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 high-stress components, wear-resistant parts and tear-resistant 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 modifiers and reinforcing fillers, featuring ultra-high tear strength, tear-resistant, durable, fine uniform closed-cell structure, good elasticity and tear stability. It has a tear strength of ≥35 kN/m, tear-resistant, no tearing, good durability, effectively withstanding high stress and tear force, solving the problem of traditional foaming materials’ poor tear resistance in high-stress scenarios. Compatible with most of our tear-resistant products, it is ideal for tear-resistant components, high-stress buffers and durable scenarios.
