Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high-flame-retardant UL94 V0 grade core product, specially developed for electrical equipment, industrial control and fire-safe environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with environmentally friendly flame retardants and anti-dripping modifiers, featuring UL94 V0 flame retardant grade, self-extinguishing within 10 seconds, no dripping, fine uniform closed-cell structure, good elasticity and flame retardant stability. It effectively inhibits flame spread, avoids fire expansion, solving the problem of traditional foaming materials’ flammability in high-risk scenarios. Compatible with most of our electrical and fire-safe products, it is ideal for flame-retardant components, fire-proof buffers and high-temperature flame-retardant scenarios.

Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into flame-retardant components, no professional flame-retardant operation skills required, improving production efficiency.
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 flame retardancy and fire safety).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform flame retardancy and closed-cell structure, avoid flame penetration).
3. Pour the mixture into flame-retardant component mold (paired with electronic potting compound), foam and cure at room temperature or by heating (heating helps enhance flame retardant stability).
4. After full curing, test flame retardancy (UL94 V0 grade) to confirm qualification, then use in high-risk flame-retardant scenarios.
Application Scenarios
Focus on flame-retardant scenarios: Electrical equipment flame-retardant buffers (paired with electronic potting compound), industrial control fire-proof parts (paired with high-precision mold silicone), flame-retardant packaging (paired with Liquid Tank Silicone), fire-safe environment components (paired with robot silicone), and flame-retardant robot parts (paired with robot silicone). It helps fire safety industry buyers improve fire protection level and avoid fire hazards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, UL94 V0 flame retardant certification, SGS flame retardant test certification, excellent flame retardancy and fire safety, meeting the flame-retardant procurement requirements of B2B buyers in electrical, industrial control and fire safety industries, facilitating export to global markets.
Customization Options
Customizable flame retardant grade (UL94 V0 grade for 0.8mm thickness for high-demand scenarios), self-extinguishing time (≤5s for high-demand scenarios), foaming ratio and hardness, adapting to different high-risk flame-retardant requirements, helping buyers optimize fire safety effect.
Production Process
Flame-retardant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add environmentally friendly flame retardants and anti-dripping modifiers) → precision mixing → flame retardant test (UL94 V0) → self-extinguishing test → standardized curing → flame retardant stability inspection → packaging. Strict flame retardant testing ensures product UL94 V0 grade and high fire safety.
