Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a compression set resistant shape retention core product, specially developed for compression, sealing and shape-sensitive environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with shape retention agents and compression stabilizers, featuring excellent compression set resistance, anti-deformation, fine uniform closed-cell structure, good elasticity and shape stability. It has a compression set of ≤10% at 150℃ for 22h, no permanent compression, can quickly recover its original shape after compression, effectively solving the problem of traditional foaming materials’ poor shape retention in compression scenarios. Compatible with most of our industrial and sealing products, it is ideal for compression-resistant components, shape-retaining buffers and sealing scenarios.
