2. High temperature: temperature - 200 ~ + 250 ℃;Electric heating plate short-term resistant to 300 ℃, flame heating need to be used in the asbestos online.
3. Good low temperature resistance: - 196 ℃ can keep the 5%;
4. Corrosion resistance: with remarkable chemical resistance, it can tolerate almost all chemical solvents (strong acid, strong alkali and various organic solvents etc);
5. Insulation: dielectric performance is independent of temperature and frequency;
