Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high tear strength tensile core product, specially developed for high-stress, tensile and tear-prone 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 tensile modifiers, featuring ultra-high tear strength, high tensile strength, fine uniform closed-cell structure, good elasticity and mechanical stability. It has a tear strength of ≥15 kN/m and tensile strength of ≥2.5 MPa, can withstand high stress and tensile force, no tearing or breakage, 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 high-stress components, tear-resistant buffers and tensile scenarios.
