Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a UV-stable anti-yellowing core product, specially developed for outdoor products, solar equipment and UV-exposed scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with UV absorbers and anti-yellowing agents, featuring UV resistance grade UVA 400, no yellowing, no degradation, fine uniform closed-cell structure, good elasticity and UV stability. It has no yellowing (ΔE ≤1.0 after 1000h UV irradiation), no performance degradation, effectively adapting to long-term UV exposure, solving the problem of traditional foaming materials’ yellowing and degradation in UV-exposed scenarios. Compatible with most of our outdoor and solar products, it is ideal for UV-stable components, UV-resistant buffers and UV-exposed scenarios.

How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting UV stability and anti-yellowing).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform UV stability and closed-cell structure, no UV penetration).
3. Pour the mixture into UV-stable component mold (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating (heating helps enhance UV stability).
4. After full curing, test UV stability (ΔE ≤1.0 after 1000h UV irradiation) to confirm qualification, then use in UV-exposed and outdoor scenarios.
Application Scenarios
Focus on UV-exposed scenarios: Outdoor product UV-resistant buffers (paired with industrial mold silicone rubber), solar equipment UV-stable parts (paired with robot silicone), UV-resistant packaging (paired with Liquid Tank Silicone), outdoor machinery components (paired with high-precision mold silicone), and UV-stable robot parts (paired with robot silicone). It helps outdoor and solar industry buyers avoid yellowing and degradation in UV-exposed environments.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS UV stability test certification, excellent UV resistance and anti-yellowing performance, meeting the UV-stable procurement requirements of B2B buyers in outdoor, solar and UV-exposed industries, facilitating export to global markets.
Customization Options
Customizable UV resistance grade (UVA 400+ for high-demand scenarios), anti-yellowing performance (ΔE ≤0.5 after 1000h UV irradiation for high-demand scenarios), foaming ratio and hardness, adapting to different UV-exposed requirements, helping buyers optimize UV stability effect.
Production Process
UV-stable-oriented production process: High-purity UV-resistant Silicone raw materials → formula optimization (add UV absorbers and anti-yellowing agents) → precision mixing → UV stability test → anti-yellowing test → standardized curing → UV stability inspection → packaging. Strict UV testing ensures product UV resistance and no yellowing.
