F881, equivalent to NEMA FR4 and IEC EPGC202, offers high mechanical strength at room temperatures, good electrical performance under both dry and wet conditions, UL94V-0. F881A is designed for mechanical, electrical and electronic applications.
The mechanical properties, dimensional stability, impact resistance and moisture resistance of F881 are higher than those of paper substrate. Its electrical performance is excellent, the operating temperature is high, and its own performance is little affected by the environment.
F881 (NEMA FR4) material stands out for its exceptional flame retardant properties, achieving the stringent UL94 V-0 classification. This premium-grade material demonstrates outstanding fire resistance by self-extinguishing within seconds when exposed to flame, effectively inhibiting fire propagation. Its superior performance makes it particularly suitable for applications with rigorous fire safety standards, including:
- Electronic components and circuit boards
- Aerospace instrumentation
- Automotive electrical systems
- Industrial control equipment
The material's compliance with international fire safety regulations ensures reliable protection against electrical fires while maintaining excellent mechanical and electrical properties.
F881(NEMA FR4) can generally be used as a high voltage resistant terminal to withstand high voltages and is usually able to handle voltage levels from thousands of volts (KV) to tens of thousands of volts to prevent electrical breakdown and electrical failure to ensure electrical isolation and safety.
High voltage resistant terminal plays an important role in the distribution, management and connection of high voltage circuits. These terminals provide electrical isolation and safety, ensuring reliable circuit operation and reducing potential hazards in high-voltage circuits. Therefore, in the design and maintenance of high voltage system, it is very important to choose the appropriate high voltage resistant terminal.
