Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high-adhesion multi-substrate bonding core product, specially developed for bonding, composite components and multi-material assembly environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with adhesion promoters and bonding modifiers, featuring ultra-high adhesion strength, multi-substrate compatibility, fine uniform closed-cell structure, good elasticity and adhesion stability. It has an adhesion strength of ≥1.5 MPa, strong bonding with metal, plastic, glass and other substrates, no peeling, effectively solving the problem of traditional foaming materials’ poor adhesion in multi-material assembly scenarios. Compatible with most of our industrial and composite products, it is ideal for bonding components, composite buffers and multi-substrate assembly scenarios.
