Material Data Sheet
Material: PSU 1000 Polysulfone (PSU)
PolysulfonePolysulfone is a amber semi-transparent, heat-resistant, high performance engineering thermoplastic. It offers a broad range of temperature capabilities, good thermal and eletrical insulation characteristics and is hydrolysis resistant. Polysulfone also offers good radiation stability and low ionic impurity. PSU 1000 Polysulfone offers high chemical resistance to acidic and salt solution, and good resistance to detergents, hot water and steam. PSU 1000 is FDA, USDA, Sa-Dairy compliant.
