Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a sound-absorbing high-sound-absorption-coefficient core product, specially developed for noise control, acoustic equipment and sound-absorbing scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with sound-absorbing fillers and noise-reduction modifiers, featuring ultra-strong sound absorption, noise reduction, fine uniform closed-cell structure, good elasticity and sound-absorption stability. It achieves a sound absorption coefficient of ≥0.6 at 1000-4000Hz, effectively absorbing noise, reducing noise pollution, solving the problem of traditional foaming materials’ poor sound absorption in noise control scenarios. Compatible with most of our noise control and acoustic products, it is ideal for sound-absorbing components, noise-reduction buffers and sound-absorbing scenarios.
