The raw material belt is made of polytetrafluoroethylene (F4, PTFE) and has a series of excellent performance:
1. High temperature resistance: long-term use temperature: 200-260 ℃;
2. Low temperature resistance: soft at - 100 ℃;
3. Corrosion resistance: resistant to aqua regia and all organic solvents;
4. Weather resistance: the best aging life of plastics;
5. High lubrication: it has the minimum friction coefficient (0.04) among plastics;
6. Non sticky: it has the minimum surface tension among solid materials without adhering to any substance;
7. No toxicity: physiological inertia;
8. Excellent electrical performance: ideal C-grade flange material.
