Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high sound insulation noise-reduction core product, specially developed for sound insulation equipment, noise reduction scenarios and soundproof components. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with sound insulation modifiers and porous fillers, featuring ultra-strong sound insulation performance, sound transmission loss ≥35 dB at 1000Hz, noise reduction, soundproof, fine uniform closed-cell structure, good elasticity and sound insulation stability. It effectively blocks noise transmission, reduces noise pollution, solving the problem of traditional foaming materials’ poor sound insulation in noise-prone scenarios. Compatible with most of our sound insulation products, it is ideal for soundproof components, noise-reduction buffers and sound insulation scenarios.
