Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a sound-absorbing noise-reducing core product, specially developed for noise-prone, sound-insulation and low-noise 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 porous structure design, featuring ultra-high sound absorption coefficient, effective noise reduction, fine uniform closed-cell structure, good elasticity and sound-absorbing stability. It has a sound absorption coefficient of ≥0.6 @1000Hz, can effectively absorb noise and reduce noise transmission, effectively solving the problem of traditional foaming materials’ poor sound absorption and high noise transmission. Compatible with most of our industrial and high-temperature products, it is ideal for noise-reduction components, sound-insulation buffers and low-noise scenarios.
