Radel® Family
Radel® WM
Radel® Polyphenylsulfone (PPSU) is an amorphous transparent high performance thermoplastic. It is known for its high heat resistance, extreme toughness, high flexural and tensile strength, excellent hydrolytic stability and good resistance to a broad range of chemicals including aqueous mineral acids, bases, and oxidizing agents and most solvents. Additionally, PPSU is inherently flame resistant.
