Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a flame-retardant smoke-suppressant core product, specially developed for fire-safety, low-smoke and high-risk fire scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with flame-retardant and smoke-suppressant additives, featuring UL94 V-0 grade flame retardancy, low smoke density, self-extinguishing, no toxic smoke, fine uniform closed-cell structure, good elasticity and flame-retardant smoke-suppressant stability. It has a smoke density of ≤50, self-extinguishes within 10 seconds after leaving the fire source, no toxic smoke, effectively solving the problem of traditional flame-retardant foaming materials’ high smoke and toxic fumes. Compatible with most of our high-temperature and industrial products, it is ideal for fire-safety, low-smoke and high-risk scenarios.

Product Features & Advantages
1. Excellent Flame Retardancy: UL94 V-0 grade, self-extinguishing within 10 seconds, no dripping, solving the problem of traditional foaming materials’ poor flame retardancy and fire risks.
2. Strong Smoke Suppression: Smoke density ≤50, no toxic smoke, reducing smoke hazards in fire scenarios, improving fire safety.
3. Flame-Retardant & Elasticity Balance: While maintaining UL94 V-0 grade flame retardancy and low smoke density, it retains good elasticity and structural stability, no brittle fracture under fire, balancing fire safety and usability.
4. Compatibility with Fire-Safety Products: Compatible with HONG YE SILICONE’s high-temperature insulation silicone and industrial Mold Silicone rubber, forming a complete low-smoke fire-safety solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into flame-retardant smoke-suppressant components, no professional fire-safety 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 and smoke-suppressant performance).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure flame-retardant smoke-suppressant uniformity and closed-cell structure).
3. Pour the mixture into flame-retardant smoke-suppressant component mold (paired with high-temperature insulation silicone), foam and cure at room temperature or by heating.
4. After full curing, the product reaches UL94 V-0 grade, smoke density ≤50, ready for use in fire-safety and low-smoke scenarios.
Application Scenarios
Focus on low-smoke fire-safety scenarios: Indoor electrical equipment (paired with high-temperature insulation silicone), public place fire-safety components (paired with industrial mold silicone rubber), low-smoke robot parts (paired with robot silicone), fire-proof low-smoke packaging (paired with Liquid Tank Silicone), and high-risk low-smoke insulation (paired with high-temperature insulation silicone). It helps fire-safety buyers reduce fire and smoke hazards and protect personnel and equipment.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS flame-retardant certification, SGS smoke-suppressant certification, UL94 V-0 certification, excellent flame-retardant and smoke-suppressant performance, meeting the low-smoke fire-safety procurement requirements of B2B buyers in electrical, public and high-risk industries, facilitating export to global markets.
Customization Options
Customizable flame-retardant grade (higher than UL94 V-0 for high-demand scenarios), smoke density (≤30 for high-demand scenarios), foaming ratio and hardness, adapting to different low-smoke fire-safety requirements, helping buyers optimize fire and smoke protection effect.
Production Process
Flame-retardant smoke-suppressant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add flame-retardant and smoke-suppressant additives) → precision mixing → flame-retardant test (UL94 V-0) → smoke density test → standardized curing → fire safety inspection → packaging. Strict flame-retardant and smoke-suppressant testing ensures product low-smoke and fire-safety performance.
