Radel® 5500 black (TECASON® P MT)

black PPSU medical

TECASON P MT black is a polyphenylsulfone suited primarily to applications in the medical industry. PPSU medical grade material has improved performance in terms of temperature, impact strength and chemical resistance, and shows exceptional resistance to repeated steam autoclaving without loss of dimensional stability, or physical properties. Medical grade PPSU is available in several colored grades, as well as with an X-ray opaque XRO additive which allows for clear component visibility on fluoroscopy and X-ray. Both product lines are tested according to ISO 10993. USP Class VI information is available on the raw material.
