PTFE needle felt dust bag

The main advantages of 100% pure PTFE needle felt: PTFE fiber, PTFE base cloth, PTFE needle felt are all produced by our company, and the product quality is stable and controllable.
PTFE needle felt is a fiber with extremely stable chemical properties. Its characteristics are as follows:
1. Continuous working temperature is 260 degrees, and the instantaneous temperature is 280 degrees;
2. Not afraid of acid and alkali and oxidation, almost non-flammable;
3. The only fiber that does not age;
4. Meet the worst conditions and have an extremely long service life.
100% pure PTFE needle felt is mainly used in special complicated conditions such as chemical industry and waste incineration, and can maintain good chemical stability under various complicated working conditions.
