Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high-transparency optical clarity core product, specially developed for optical components, transparent packaging and light-transmission environments. 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 ultra-high transmittance, optical clarity, fine uniform closed-cell structure, good elasticity and transparency stability. It has a transmittance of ≥90% at 550nm, no yellowing, high light transmittance, effectively ensuring light transmission, solving the problem of traditional foaming materials’ opacity in light-transmission scenarios. Compatible with most of our optical and transparent products, it is ideal for transparent components, light-transmission buffers and optical scenarios.
