Product Summary
Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a flame-retardant core product, focusing on high-temperature fire safety and flame retardancy. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with flame-retardant components, featuring UL94 V-0 grade flame retardancy, self-extinguishing performance, fine uniform pores and stable high-temperature performance, which can effectively prevent fire spread and reduce fire damage. Compatible with most of our core products, it is ideal for fire safety equipment sealing, filling and protection.

Product Features & Advantages
1. Excellent Flame Retardancy: UL94 V-0 grade flame retardancy, self-extinguishing within 3 seconds after leaving the fire source, no dripping, no toxic fumes, higher than industry average flame retardant standards, solving the problem of traditional foaming materials’ flammability and fire hazard.
2. High-Temperature Fire Safety: Stable performance at high temperature, no deformation, no melting, no release of toxic substances even under 250℃ short-term high temperature, effectively preventing fire spread and protecting equipment and personnel safety.
3. Flame Retardancy & Performance Balance: While maintaining excellent flame retardancy, it retains good elasticity and sealing performance, fine uniform pores ensure flame retardant uniformity, no local flammable defects.
4. Fire Safety Compatibility: Compatible with HONG YE SILICONE’s industrial Mold Silicone rubber and electronic Potting Compound, forming a complete fire safety solution, enabling one-stop procurement for fire safety-oriented buyers. 5. Easy Flame-Retardant Operation: 1:1 simple mixing ratio, good flowability, easy to fill into fire safety equipment gaps and molds, 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 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure flame retardant uniformity and sealing performance).
3. Pour the mixture into fire safety equipment mold or gap (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating.
4. After full curing, the product has UL94 V-0 grade flame retardancy, can be directly used in fire safety scenarios, effectively preventing fire spread.
Application Scenarios
Focus on fire safety scenarios: Fire equipment sealing (paired with industrial mold silicone rubber), electronic product fire protection potting (paired with electronic potting compound), automotive fire safety parts (paired with industrial mold silicone rubber), high-temperature equipment fire protection filling (paired with Liquid Tank Silicone), and fire-resistant robot components (paired with robot silicone). It helps fire safety-oriented buyers improve product fire safety performance and meet fire safety standards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, UL94 V-0 flame retardant certification, meeting the fire safety procurement requirements of B2B buyers in various industries, facilitating export to global markets with strict fire safety standards.
Customization Options
Customizable flame retardant grade (up to UL94 V-1 for high-demand scenarios), foaming ratio, viscosity and curing time, adapting to different fire safety requirements of various equipment, helping buyers optimize product fire safety performance.
Production Process
Flame-retardant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (enhance flame retardancy and self-extinguishing performance) → precision mixing → flame retardant performance test (UL94 V-0 test) → standardized curing → high-temperature fire safety inspection → packaging. Strict flame retardant testing ensures product fire safety performance.
