Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a flame-retardant & smoke-suppression low-smoke core product, specially developed for public places, electrical equipment and low-smoke 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 flame retardants and smoke-suppression agents, featuring UL94 V0 flame retardancy, low smoke emission, fine uniform closed-cell structure, good elasticity and flame-smoke stability. It achieves UL94 V0 grade flame retardancy, smoke density ≤50 Ds, no toxic smoke, effectively inhibiting flame spread and reducing smoke emission, solving the problem of traditional flame-retardant foaming materials’ high smoke emission in fire scenarios. Compatible with most of our flame-retardant products, it is ideal for low-smoke flame-retardant components, smoke-suppression buffers and low-smoke scenarios.

4. Compatibility with Flame-Retardant Products: Compatible with HONG YE SILICONE’s electronic Potting Compound and industrial Mold Silicone rubber, forming a complete low-smoke flame-retardant solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into low-smoke flame-retardant components, no professional flame-smoke 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 smoke suppression).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform flame-smoke performance and closed-cell structure, no flame/smoke penetration).
3. Pour the mixture into low-smoke flame-retardant component mold (paired with electronic potting compound), foam and cure at room temperature or by heating (heating helps enhance flame-smoke stability).
4. After full curing, test flame retardancy (UL94 V0) and smoke density (≤50 Ds) to confirm qualification, then use in low-smoke flame-retardant scenarios.
Application Scenarios
Focus on low-smoke flame-retardant scenarios: Public place flame-retardant buffers (paired with electronic potting compound), electrical equipment low-smoke parts (paired with industrial mold silicone rubber), low-smoke packaging (paired with Liquid Tank Silicone), public safety components (paired with robot silicone), and low-smoke robot parts (paired with robot silicone). It helps public safety industry buyers reduce fire hazards and smoke risks.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, UL94 V0 certification, SGS flame retardant & smoke suppression certification, excellent flame retardancy and low smoke emission, meeting the low-smoke flame-retardant procurement requirements of B2B buyers in public safety, electrical and low-smoke industries, facilitating export to global markets.
Customization Options
Customizable flame retardant grade (UL94 V0 grade for 0.8mm thickness), smoke density (≤30 Ds for high-demand scenarios), foaming ratio and hardness, adapting to different low-smoke flame-retardant requirements, helping buyers optimize safety effect.
Production Process
Flame-smoke-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add flame retardants and smoke-suppression agents) → precision mixing → flame retardant test (UL94 V0) → smoke suppression test → standardized curing → flame-smoke stability inspection → packaging. Strict flame-smoke testing ensures product flame retardancy and low smoke emission.
