Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a sound-insulating noise-reduction core product, specially developed for sound insulation equipment, noise control projects and sound insulation scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with sound-insulating fillers and noise-reduction modifiers, featuring ultra-high sound insulation efficiency, sound absorption, fine uniform closed-cell structure, good elasticity and sound insulation stability. It has a sound insulation efficiency of ≥45 dB at 1000-2000Hz, effectively blocking noise transmission, reducing noise pollution, solving the problem of traditional foaming materials’ poor sound insulation in noise scenarios. Compatible with most of our sound insulation products, it is ideal for sound-insulating components, noise-reduction buffers and sound insulation scenarios.
