Medical Grade PPSU Board Hydrolysis Resistant

In medical device and pharmaceutical equipment manufacturing, material safety, stability, and durability directly define product quality. Medical Grade PPSU (Polyphenylsulfone) Sheet stands as an ideal alternative to metals and conventional plastics, boasting exceptional overall performance—with outstanding hydrolysis resistance as its defining advantage.

Featuring a robust molecular structure with stable sulfone and biphenyl units, PPSU delivers superior hydrolytic stability. It withstands thousands of cycles of high-temperature (134°C) high-pressure steam sterilization without hydrolysis, cracking, warping, or performance degradation. Even under prolonged hot and humid conditions, it maintains exceptional dimensional accuracy and mechanical strength, perfectly suited for the rigorous demands of hospital autoclaving and frequent cleaning/disinfection.

As a certified medical-grade material, PPSU sheet complies with ISO 10993, FDA 21CFR, and USP Class VI standards. It is non-toxic, BPA-free, and offers excellent biocompatibility for safe contact with human tissue and bodily fluids. Additionally, it provides high heat resistance (continuous use at 180°C, HDT 207°C), superior impact strength, resistance to acids, alkalis and disinfectants, inherent flame retardancy with low smoke emission, and excellent electrical insulation—fully meeting the stringent requirements of medical equipment.

Typical applications include: medical sterilization trays, surgical instrument holders, dental devices, endoscope components, ventilator parts, pharmaceutical equipment panels, and high-temperature laboratory support plates. Compared to PSU and PEI, PPSU offers greater toughness and superior chemical resistance; versus stainless steel, it is lighter, more machinable, and cost-effective.
