What is the difference between Polysulfone and PVDF?

Polysulfone is a high-performance thermoplastic with excellent thermal stability, transparency, and resistance to aqueous acids and bases. PVDF provides outstanding chemical resistance to solvents and halogens with excellent mechanical properties and purity.

When should I use Polysulfone instead of PVDF?

Use Polysulfone for: Medical devices, water filtration membranes, hot water systems, sterilizable equipment. Use PVDF for: Aggressive chemical handling, semiconductor processing, piping for solvents and acids.

Which has better chemical resistance: Polysulfone or PVDF?

Polysulfone has 155 chemicals rated Excellent (A) at 20°C, while PVDF has 687. Including Good (B) ratings, Polysulfone is compatible with 184 chemicals and PVDF with 837.
