PPSU (Polyphenylsulfone) is the toughest member of the polysulfone family with outstanding impact resistance, excellent chemical resistance and the ability to withstand repeated steam sterilisation.
Description
PPSU provides the best balance of toughness, chemical resistance and heat performance in the sulfone polymer family. Tg ~220°C, notched Izod impact >690 J/m. Resistant to hydrolysis even after 1000+ autoclave cycles. Amber transparent in natural form.
Applications
PPSU is used in surgical instrument trays, baby bottles (BPA-free), aircraft interior panels, plumbing fittings and gas masks.
