F870CP, similar to NEMA G7, is a laminate sheet made from high-performance silicone resin and a woven fiberglass substrate. It is a flame-resistant material featuring a low dissipation factor with high heat and superior arc resistance. F870 CP (G7) works well in wet or dry conditions and are ideal for applications requiring solid mechanical and electrical properties. Usually used as the insulating structural parts under high temperature and arc resistance working conditions.
Product Advantages
- High-Temperature Resistance: Stable operation within a wide temperature range of -60°C to +300°C, with long-term heat resistance reaching Class H (180°C).
- Electrical Insulation: Parallel layer withstand voltage ≥25kV (in oil at 90°C), dielectric constant ≤6 (1MHz), suitable for high-voltage switches, arc protection, and similar applications.
- Mechanical Strength: Vertical layer flexural strength ≥120MPa, impact strength (notched) ≥25.5kJ/m², ensuring structural stability.
- Safety and Environmental Protection: Excellent flame retardancy.
Product Application
1. Electrical Equipment: Insulating barriers for high-voltage switchgear, transformer winding supports;
2. New Energy Vehicles: Insulating brackets for battery packs, motor slot wedges, and arc-resistant components;
3. Electronic Packaging: Potting substrates for high-power modules, heat dissipation substrates for LEDs;
4. Aerospace: Thermal insulation layers for airborne equipment, radiation-resistant structural components.
