Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a sound absorption noise reduction core product, specially developed for sound absorption, noise reduction and quiet environment 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 additives and noise reduction modifiers, featuring high sound absorption, effective noise reduction, fine uniform closed-cell structure, good elasticity and sound stability. It has a sound absorption coefficient of ≥0.6 at 1000-4000Hz, effectively absorbing sound waves, reducing noise transmission, creating a quiet environment, solving the problem of traditional foaming materials’ poor sound absorption in noise-prone scenarios. Compatible with most of our industrial and construction products, it is ideal for sound absorption components, noise reduction buffers and quiet environment scenarios.
