Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a noise reduction sound insulation core product, specially developed for noise reduction, sound insulation and low-noise environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with sound insulation fillers and noise absorption modifiers, featuring strong sound insulation, noise absorption, fine uniform closed-cell structure, good elasticity and sound insulation stability. It has a sound transmission loss of ≥25 dB at 1000Hz, effective noise absorption, no sound leakage, can reduce environmental noise, effectively solving the problem of traditional foaming materials’ poor sound insulation in low-noise scenarios. Compatible with most of our industrial and mechanical products, it is ideal for noise reduction components, sound insulation buffers and low-noise scenarios.
