Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high-transparency optical-grade core product, specially developed for optical equipment, transparent components and high-transparency scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with high-transparency raw materials and anti-yellowing agents, featuring high transmittance, high clarity, fine uniform closed-cell structure, good elasticity and optical stability. It has a transmittance of ≥90% at 400-800nm, high clarity, no yellowing, no haze, effectively maintaining optical performance, solving the problem of traditional foaming materials’ poor transparency in optical scenarios. Compatible with most of our optical and electronic products, it is ideal for transparent components, optical buffers and high-transparency scenarios.
