About Polysulfone (PSU or PSF) material

Polysulfone (PSU or PSF) is an amorphous high performance polymer, the glass transition temperature is 187 °C. It is an amber transparent plastic with excellent properties, including high mechanical strength and rigidity, excellent dimensional stability, outstanding resistance to hydrolysis, good chemical compatibility, excellent radiation stability and good creep strength.

Polysulfone (PSU or PSF) can work well at a wide range tempreture from -100°C (-150°F) to 150°C (300°F), it offers similar mechanical strength with PEI Plastic. Comparing with polyphenylene sulfone (PPSU) and polyethersulfone (PES), PSU offer better transparency. It is also a suitable material to replace polycarbonate plastic or acrylic for applications, for example high temperature hot water, steam, corrosion, etc.

Frequently used profiles are PSU sheet, rod, tube, film, etc. Otherwise, PSU plastic can be injected molding into some complicated parts.
