PPSU

HPMs – High-performance materials

PPSU

Polyphenylsulphone is an amorphous thermoplastic with high resistance to heat and chemicals. It is also resistant to hydrolysis, and in practice it can be sterilised as often as necessary. The material is also dimensionally accurate over a wide range of temperatures. We deliver PPSU as sheets and rods.
