Fluoropolymers are pre-eminent among high performance thermoplastics. With their outstanding range of properties combined with a very good cost-performance ratio, these materials are finding ever more membrane applications. In general fluoropolymers offer:
- Exceptional chemical resistance
- Very good control of pore size and pore size distribution
- High membrane strength
- High thermal properties
- Low surface energy
- Outstanding stability to pH from 1 to 14
