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

2. No Dripping & No Smoke: No dripping during combustion, no toxic smoke, reducing fire spread risk and environmental pollution, meeting fire safety standards.
3. Flame Retardancy & Elasticity Balance: While maintaining V0-grade flame retardancy, it retains good elasticity and structural stability, no brittle fracture, balancing fire safety and usability.
4. Compatibility with Flame-Retardant Products: Compatible with HONG YE SILICONE’s industrial mold silicone rubber and high-precision mold silicone, forming a complete flame-retardant solution, enabling one-stop procurement.
5. 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).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform flame retardancy and closed-cell structure, no flame penetration).
3. Pour the mixture into flame-retardant component mold (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating (heating helps enhance flame-retardant stability).
4. After full curing, conduct UL94 V0 flame retardant test (self-extinguishing ≤10s, no dripping) to confirm qualification, then use in high-flame-retardant scenarios.
Application Scenarios
Focus on flame-retardant scenarios: High-flame-retardant equipment buffers (paired with industrial mold silicone rubber), electrical enclosure flame-retardant parts (paired with high-precision mold silicone), flame-retardant packaging (paired with Liquid Tank Silicone), fire-safe machinery components (paired with industrial mold silicone rubber), and flame-retardant robot parts (paired with robot silicone). It helps electrical and fire safety industry buyers prevent fire spread and meet flame-retardant standards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, UL94 V0, SGS flame retardant test certification, excellent high flame retardancy, meeting the flame-retardant procurement requirements of B2B buyers in electrical, fire safety and flame-retardant industries, facilitating export to global markets.
Customization Options
Customizable flame retardant grade (enhanced V0 for high-demand scenarios), self-extinguishing time (≤5s for high-demand scenarios), foaming ratio and hardness, adapting to different high-flame-retardant requirements, helping buyers optimize fire safety performance.
Production Process
Flame-retardant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add high-efficiency flame retardants and anti-dripping modifiers) → precision mixing → flame retardant test (UL94 V0) → combustion test → standardized curing → flame-retardant stability inspection → packaging. Strict flame retardant testing ensures product V0-grade flame retardancy and fire safety.
