Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a flame-retardant core product, specially developed for fire-sensitive and flame-retardant-required scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with environment-friendly flame-retardant components, featuring UL94 V-0 grade flame retardancy, self-extinguishing, fine uniform closed-cell structure, good elasticity and flame-retardant stability. It can effectively inhibit combustion, self-extinguish within 3 seconds after leaving the fire source, no dripping, no toxic fumes, reducing fire spread risk, ensuring equipment and personnel safety. Compatible with most of our insulation and industrial products, it is ideal for electrical, automotive and industrial flame-retardant scenarios.

Product Features & Advantages
1. Superior Flame Retardancy: UL94 V-0 grade, self-extinguishing within 3 seconds, no dripping, no toxic fumes, solving the problem of traditional foaming materials’ flammability and fire spread risks.
2. Environment-Friendly Flame Retardant: Adopts environment-friendly flame-retardant components, non-toxic, no harmful gas emission during combustion, meeting global environmental protection standards.
3. Flame-Retardant & Usability Balance: While maintaining excellent flame retardancy, it retains good elasticity and sealing performance, closed-cell structure enhances fire resistance, balancing flame protection and practicality.
4. Compatibility with Flame-Retardant Products: Compatible with HONG YE SILICONE’s high-temperature insulation silicone and industrial Mold Silicone rubber, 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-retardant performance).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure flame-retardant uniformity and closed-cell structure).
3. Pour the mixture into flame-retardant component mold (paired with high-temperature insulation silicone), foam and cure at room temperature or by heating.
4. After full curing, the product meets UL94 V-0 grade, self-extinguishing, ready for use in fire-sensitive and flame-retardant-required scenarios.
Application Scenarios
Focus on flame-retardant scenarios: Electrical equipment flame-retardant sealing (paired with Electronic Potting Compound), automotive flame-retardant components (paired with industrial mold silicone rubber), industrial fire-sensitive equipment protection (paired with industrial mold silicone rubber), flame-retardant robot parts (paired with robot silicone), and flame-retardant packaging (paired with Liquid Tank Silicone). It helps fire-sensitive buyers reduce fire risks and ensure equipment safety.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, UL94 V-0 flame-retardant certification, SGS flame-retardant certification, excellent flame-retardant and self-extinguishing performance, meeting the flame-retardant procurement requirements of B2B buyers in electrical, automotive and industrial industries, facilitating export to global markets.
Customization Options
Customizable flame-retardant grade (UL94 V-1/V-0 optional), self-extinguishing time, foaming ratio and hardness, adapting to different flame-retardant requirements, helping buyers optimize fire protection effect.
Production Process
Flame-retardant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add environment-friendly flame-retardant components) → precision mixing → flame-retardant test (UL94 certification) → standardized curing → fire resistance inspection → packaging. Strict flame-retardant testing ensures product fire safety performance.
