Descriptionmetasulfon® is a high-temperature-resistant, amorphous high-performance thermoplastic. PSU was put on the market in 1965. Polysulfones have good heat resistance and heat aging resistance (-100° C – +190° C). It has a high hardness and strength, very good hydrolysis and high radiation resistance (permeable to microwaves). However, it is notch sensitive.Applicationsfood processing industry (milking machines, pumps, valves)parts that need to be cleaned and sterilised repeatedly
