Products Description
Polypropylene string wound filter is a kind of depth filtration element made of polypropylene fiber as raw material, which is wound by a specific process. It is mainly used to remove suspended solids, particles, impurities, etc. from liquids.
The use of 100% polypropylene material has the following advantages:
- Chemical compatibility: acid and alkali resistance, organic solvents (applicable PH 1-14).
- No dissolved matter: FDA-approved material, no fiber shedding, to protect the purity of the fluid.
- Thermal stability: working temperature ≤ 60 ℃, no deformation and degradation.
Key features
- Polypropylene fibers are tightly and uniformly woven, efficiently intercepting all kinds of tiny impurities.
- The material has excellent chemical resistance and can withstand acid and alkali and other chemical substances.
- Supporting backwashing or chemical cleaning, the cartridge can be reused to extend the service cycle.
- Stable and reliable performance ensures the safety of materials without pollution, applicable to drinking water, industrial water, pharmaceuticals and oil and other areas of fluid purification.
