PSU is a great option for precision production and represents a suitable alternative to polycarbonate. Especially there where a higher chemical, temperature and steam-sterilisation resistance is required. This plastic has a high ionic purity and is also radiation and hydrolysis resistant. The material is dimensionally stable, is well machinable, is suitable for contact with food and has an application temperature from -100 to +150°C. PSU is often found in milking machines, filter plates and microwave components.
