At temperatures over 400°F (205°C), PBI exhibits the highest strength and stiffness of any unfilled plastic. It is even capable of withstanding brief exposure to temperatures as high as 1400°F (760°C) and performs best in an oxygen-free environment.
- Excellent hardness
- Low coefficient of friction
- Outstanding Tg and heat deflection temperature
- Relatively low coefficient of thermal expansion
- High volume resistivity
- Very good plasma resistance
