Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high pressure-resistant compression-stable core product, specially developed for high-pressure, compression-required and high-load scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with pressure-resistant fillers and compression stabilizers, featuring ultra-high pressure resistance, compression stability, fine uniform closed-cell structure, good elasticity and pressure stability. It has a compressive strength of ≥5 MPa and compression set of ≤5% at 150℃ for 22h, can withstand high pressure and long-term compression, no deformation, effectively solving the problem of traditional foaming materials’ poor pressure resistance in high-pressure scenarios. Compatible with most of our industrial and aerospace products, it is ideal for high-pressure components, compression-stable buffers and high-load scenarios.
