Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a low-noise-reduction acoustic insulation core product, specially developed for noise-reduction equipment, automotive interiors and quiet 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-absorbing fillers and noise-insulation modifiers, featuring high noise reduction coefficient, effective sound absorption, fine uniform closed-cell structure, good elasticity and noise-reduction stability. It has a noise reduction coefficient of ≥0.6, effective noise isolation, sound absorption effect ≥85%, effectively reducing noise transmission, solving the problem of traditional foaming materials’ poor noise reduction in quiet environment scenarios. Compatible with most of our noise-reduction and automotive products, it is ideal for noise-reduction components, acoustic insulation buffers and quiet environment scenarios.
