Product Features & Advantages
1. UL94 V0 Flame-Retardant Grade: Meets international UL94 V0 flame-retardant standard, self-extinguishing within 10s after ignition, no dripping, no combustion spread, effectively preventing fire expansion, solving the problem of traditional foaming materials’ flammability and poor fire resistance.
2. High-Safety Protection: Flame-retardant performance is stable, no toxic gas released during combustion, protecting equipment and personnel safety, reducing fire loss, meeting high-safety procurement requirements.
3. Flame-Retardant & Performance Balance: While maintaining V0 flame-retardant grade, it retains good elasticity and sealing performance, closed-cell structure prevents fire penetration, ensuring dual protection of fire resistance and sealing.
4. High-Safety Compatibility: Compatible with HONG YE SILICONE’s industrial Mold Silicone rubber and electronic Potting Compound, forming a complete high-safety solution, enabling one-stop procurement for high-safety buyers. 5. Easy Flame-Retardant Operation: 1:1 simple mixing ratio, good flowability, easy to process into fire-resistant 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 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure flame-retardant uniformity and closed-cell structure).
3. Pour the mixture into high-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 reaches UL94 V0 flame-retardant grade, self-extinguishing, no dripping, ready for use in high-safety scenarios.
Application Scenarios
Focus on high-safety scenarios: Electronic equipment fire-resistant sealing (paired with electronic potting compound), industrial high-safety equipment filling (paired with industrial mold silicone rubber), automotive fire-resistant components (paired with industrial mold silicone rubber), high-safety robot parts (paired with robot silicone), and fire-resistant insulation (paired with high-temperature insulation silicone). It helps high-safety buyers improve product safety and meet fire protection standards.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS flame-retardant certification (UL94 V0), meeting the high-safety procurement requirements of B2B buyers in electronics, industrial and automotive industries, facilitating export to global high-safety markets.
Customization Options
Customizable flame-retardant grade (up to UL94 V0+, no dripping), foaming ratio, hardness and viscosity, adapting to different high-safety requirements, helping buyers optimize product fire-resistant performance.
Production Process
Flame-retardant-oriented production process: High-purity flame-retardant Silicone raw materials → formula optimization (add high-efficiency flame-retardant components) → precision mixing → flame-retardant test (UL94 V0) → standardized curing → fire resistance inspection → packaging. Strict flame-retardant testing ensures product high safety.
