PSU/P/PPSU is a thermally stable thermoplastic consisting mainly of phenyl and biphenyl groups linked by ether and sulfone groups. The material is resistant to high and low temperatures, has excellent impact strength, and is chemical and solvent resistant. It is, therefore, a popular choice for electrical insulation applications
1980: Start of industrial production
Parts made out of polyarylsulfones have excellent dimensional stability and remain strong, rigid, and tough up to temperatures close to the glass transition temperature. The key features are:
Polyarylsulfone is used in the automotive industry for:
Polyarylsulfone is used in the electrical and electronics industry for:
Elsewhere, polyarylsulfone is used to make:
Polyarylsulfones are amorphous, thermoplastic polycondensation products with the following basic structures:
Polyarylsulfone applications are 100% recyclable, either mechanically or as feedstock, and energy from waste can be recovered at incineration plants.
The most appropriate recovery options depend on numerous conditions. These include local legislation, plastics part design, access to sorting facilities and regional logistics and recycling costs.
