Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a compression set resistant high rebound core product, specially developed for compression, buffer and rebound-required scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with compression-resistant and rebound modifiers, featuring ultra-low compression set, high rebound rate, fine uniform closed-cell structure, good elasticity and compression stability. It has a compression set of ≤10% @70℃, 22h and rebound rate of ≥90%, can withstand long-term compression without permanent deformation, effectively solving the problem of traditional foaming materials’ poor compression set resistance and low rebound rate. Compatible with most of our industrial and robot products, it is ideal for compression buffers, rebound components and pressure-resistant scenarios.
