Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is an acoustic insulation noise reduction core product, specially developed for noise reduction, acoustic insulation and sound absorption scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, designed with gradient foaming structure (density 0.1-0.6g/cm³ gradient distribution), which can effectively absorb and isolate noise of different frequencies, especially low-frequency noise. It has excellent acoustic insulation (sound insulation amount ≥35 dB), low-frequency sound absorption coefficient ≥0.8 at 250Hz, fine uniform closed-cell pores (partial gradient distribution), good elasticity and acoustic stability, effectively solving the problem of poor noise reduction effect of traditional foaming materials, especially low-frequency noise. Compatible with most of our industrial and precision products, it is ideal for acoustic insulation components, noise reduction buffers and sound absorption scenarios.
