Product advantages
- Excellent electrical insulation
High surface resistance and volume resistance, suitable for high-voltage electrical equipment, PCB circuit boards and other fields.
- High mechanical strength and rigidity
The board is hard and not easy to deform, with good bending and impact resistance, and can be used as a structural support.
- High flame retardant grade (UL94 V-0)
It is not easy to burn under high temperature or fire source, with strong safety performance, suitable for occasions with high fire protection requirements.
- Dimensionally stable and good chemical resistance
It is not easy to absorb water, is not affected by moisture, is resistant to acid and alkali corrosion, and adapts to complex industrial environments.
- Good processability
It can be punched, sawed, milled and other mechanical processing, suitable for batch customization and precision component processing.
