What are the types of acid and alkali resistant filter bags?

According to different materials, sffiltech acid and alkali resistant filter bags can be divided into the following types:

1. Polypropylene (PP) acid and alkali resistant filter bag: It is mainly used for filtration under acid and alkali conditions with PH value between 2-13, and has good chemical stability and corrosion resistance.

2. (PE) polyester acid and alkali resistant filter bag: suitable for filtration under pH conditions between 4 and 9, with good mechanical strength and temperature resistance.

3. Polytetrafluoroethylene (PTFE) acid and alkali resistant filter bag: suitable for filtration under extreme acid and alkali conditions with pH values between 0 and 14, it has excellent chemical resistance and high temperature resistance.

5. Polyether ester acid and alkali resistant filter bag: suitable for filtration under pH conditions between 5-9, with good tensile strength and temperature resistance.
