PTEF filter bag is a kind of nonpolar linear polymer with completely symmetrical structure, and its macromolecular chain has spiral structure instead of zigzag shape like C and H molecular chains. PTEF dust filter bag is not easy to be damaged. Due to the inherent stability of PTEF dust filter bag and the inertia of chain structure, PTEF dust filter bag is very suitable for the comprehensive action of high temperature and chemical action.

Because of the special molecular structure of PTEF filter bag, its orientation and thermal stability are very good. It can be used for a long time at -250-260℃, and the temperature of PTEF dust filter bag can reach 300℃ in a short time. It also allows temperature fluctuations and does not become brittle at low temperatures.

At the same time, the PTEF filter bag has excellent anti-aging ability and is stable to ultraviolet rays. In addition, the PTEF dust filter bag is resistant to strong acid, alkali and strong oxidant, and the chemical properties of the PTEF filter bag are stable. PTFE dust bags has low surface energy and good hydrophobicity, and its contact angle with water is about 120.

Through finishing process, PTEF filter bag can be used as self-cleaning material. In addition, due to the chemical stability and high electronegativity of fluorine atom, its flame retardancy, adhesion and lubricity are also excellent, and the friction coefficient of PTEF filter bag is lower than that of most chemical fibers and high-performance materials.

Special PTEF filter bag is an extremely stable chemical fiber with the following characteristics:

1, continue to keep the working temperature above 250 degrees, the instantaneous temperature is 280 degrees.

2, completely afraid of acid and alkali oxidation, almost nonflammable. Only non-aging fibers.

3. The PTEF filter bag meets harsh working conditions and has a long service life, which is generally over 4 years.
