It has fine uniform closed-cell pores, -65℃-200℃ temperature resistance, 1:1 easy operation, passed SGS flame retardancy and smoke-suppressant certification, compatible with high-temperature insulation silicone and Industrial mold silicone rubber, serving B2B buyers in flame-retardant industrial and electrical industries.
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 flame-retardant, low-smoke and fire-safe 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, fine uniform closed-cell structure, good elasticity and flame-retardant stability. It is non-combustible, self-extinguishing within 10 seconds, smoke density ≤50, effectively inhibiting flame spread and smoke generation, solving the problem of traditional foaming materials’ flammability and heavy smoke in fire scenarios. Compatible with most of our high-temperature and industrial products, it is ideal for flame-retardant components, fire-safe buffers and low-smoke scenarios.

Product Features & Advantages
1. Excellent Flame Retardancy: UL94 V-0 grade, non-combustible, self-extinguishing within 10 seconds, solving the problem of traditional foaming materials’ flammability in flame-retardant scenarios.
2. Strong Smoke Suppression: Smoke density ≤50, low smoke emission, no toxic fumes, reducing smoke hazards in fire scenarios, protecting personnel and equipment.
3. Flame-Retardant & Elasticity Balance: While maintaining UL94 V-0 flame retardancy and smoke suppression, 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 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 and smoke-suppressant performance).
2. Mix and stir thoroughly for 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 has UL94 V-0 flame retardancy and low smoke emission, ready for use in flame-retardant and low-smoke scenarios.
Application Scenarios
Focus on flame-retardant scenarios: Industrial flame-retardant buffers (paired with industrial mold silicone rubber), electrical equipment flame-retardant protection (paired with Electronic Potting Compound), flame-retardant robot parts (paired with robot silicone), low-smoke packaging (paired with Liquid Tank Silicone), and fire-safe construction components (paired with high-precision mold silicone). It helps flame-retardant buyers improve fire safety and reduce fire hazards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS flame retardancy certification, UL94 V-0 certification, excellent flame-retardant and smoke-suppressant performance, meeting the flame-retardant procurement requirements of B2B buyers in industrial, electrical and construction industries, facilitating export to global markets.
Customization Options
Customizable flame retardancy level (UL94 V-1/V-0 optional), smoke density (≤30 for high-demand scenarios), foaming ratio and hardness, adapting to different flame-retardant and low-smoke requirements, helping buyers optimize fire safety protection.
Production Process
Flame-retardant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add flame-retardant and smoke-suppressant additives) → precision mixing → flame retardancy test (UL94 V-0) → smoke-suppressant test → standardized curing → fire safety inspection → packaging. Strict flame-retardant testing ensures product fire-safe performance.
