Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high-pressure-resistant anti-collapse core product, specially developed for high-pressure equipment, hydraulic systems and high-pressure 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 structural modifiers, featuring ultra-strong pressure resistance, no collapse, no deformation, fine uniform closed-cell structure, good elasticity and pressure stability. It has a compressive strength of ≥3.0 MPa and pressure resistance of ≥10 MPa, effectively withstanding high pressure, no collapse or deformation, solving the problem of traditional foaming materials’ collapse in high-pressure scenarios. Compatible with most of our high-pressure and hydraulic products, it is ideal for high-pressure components, pressure-resistant buffers and high-pressure scenarios.
