SINOYQX® Introduces High-Voltage Electrical Insulation Foam: Melamine-Based, Fully Replacing Traditional EVA and PU Foams
[Chengdu, July 2024]
SINOYQX®, a specialized manufacturer of high-performance foam materials, announces the launch of an ultra-high resistivity melamine insulation foam developed for the power, new energy, and rail transit industries. The material is engineered to replace conventional EVA foam and modified PU foam, providing safer, more durable, and environmentally friendly solutions for high-voltage insulation and integrated thermal and acoustic protection.
🎯 Key Product Advantages
✅ Significantly Enhanced Electrical Insulation
With a surface resistivity of ≥10¹⁸ Ω, this foam belongs to the high-voltage electrical insulation category, delivering insulation performance an order of magnitude higher than standard EVA foam.
✅ Integrated Flame Retardancy, Thermal, and Acoustic Performance
Certified to UL94 V-0 flame retardancy and offering excellent thermal and acoustic insulation. The foam maintains stable properties across extreme temperatures ranging from –180 to +200℃.
✅ Environmentally Friendly
Halogen-free and fully compliant with RoHS and REACH directives, meeting the rising sustainability standards in global supply chains.
