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 noise reduction equipment, automotive interiors and high-noise 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-insulating fillers and noise-absorbing modifiers, featuring ultra-strong sound insulation, effective sound absorption, fine uniform closed-cell structure, good elasticity and sound insulation stability. It has a sound insulation amount of ≥35 dB, effectively blocking noise transmission, absorbing sound waves, solving the problem of traditional foaming materials’ poor sound insulation in high-noise scenarios. Compatible with most of our automotive and construction products, it is ideal for sound-insulating components, noise-reduction buffers and high-noise environment scenarios.
