Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high sound absorption noise-reduction core product, specially developed for sound absorption equipment, noise reduction components and sound absorption scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with sound absorption modifiers and noise reduction fillers, featuring ultra-high sound absorption coefficient, good noise reduction and sound insulation, fine uniform closed-cell structure, good elasticity and sound absorption stability. It has a sound absorption coefficient of ≥0.8 at 1000Hz, effective noise reduction, sound insulation, solving the problem of traditional foaming materials’ poor sound absorption in noise-prone scenarios. Compatible with most of our sound absorption products, it is ideal for sound absorption components, noise reduction buffers and sound absorption scenarios. Technical Specifications
