Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a transparent high-light-transmittance core product, specially developed for transparent components, optical equipment and transparent scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with transparent raw materials and clarity modifiers, featuring ultra-high light transmittance, high clarity, no yellowing, fine uniform closed-cell structure, good elasticity and transparency stability. It has a light transmittance of ≥85% at 400-800nm, high clarity, no turbidity, effectively ensuring light transmission, solving the problem of traditional foaming materials’ opacity in transparent scenarios. Compatible with most of our optical and transparent products, it is ideal for transparent components, light-transmitting buffers and transparent scenarios.

How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately in a dust-free environment to eliminate sediment, ensure no impurities (avoid affecting transparency and clarity).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform transparency and closed-cell structure, no light scattering).
3. Pour the mixture into transparent component mold (paired with high-precision mold silicone), foam and cure at room temperature or by heating (heating helps enhance transparency stability).
4. After full curing, test light transmittance (≥85%) to confirm qualification, then use in transparent and optical scenarios.
Application Scenarios
