Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a chemical-resistant strong acid & alkali resistance core product, specially developed for chemical equipment, laboratory instruments and chemical-contact scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with chemical-resistant modifiers and anti-corrosion agents, featuring ultra-strong chemical resistance, resistance to strong acid (pH 1) and strong alkali (pH 14), fine uniform closed-cell structure, good elasticity and chemical stability. It has no corrosion, no degradation, no volume change (≤1.0% after 72h chemical immersion), effectively adapting to chemical-contact environments, solving the problem of traditional foaming materials’ corrosion in strong acid & alkali scenarios. Compatible with most of our chemical and laboratory products, it is ideal for chemical-resistant components, anti-corrosion buffers and chemical-contact scenarios.
