PPSU is a kind of amorphous and high functional thermoplastic. Compared with PSU and Pei, it has better impact resistance and chemical resistance.
　　
　　Through the test of autoclave failure, it is proved that PPSU has excellent hydrolytic resistance and surpasses other amorphous thermoplastics. In fact, PPSU can be placed in the steam sterilization environment indefinitely, and high-pressure steam is widely used for sterilization of medical components, which makes PPSU become the material of medical equipment. In addition, in a wide range of temperature, it can also resist the corrosion of ordinary acids and alkalis - including commercial cleaning agents.
　　
　　PPSU colors are natural （bone white）， transparent and other commonly used colors, which can also be customized. It is widely used in sterilization tray, dental and surgical instrument handle, fluid processing coupling and assembly applications. PPSU conforms to USP class VI specification. Because it can withstand welding temperature, it is suitable for electronic assembly equipment and devices. The thermal deformation temperature of PPSU is 207 ° C.
　　
　　Main features:
　　
　　1. High working temperature in air is high （continuous 180 ° C）
　　
　　2. Excellent chemical resistance and hydrolytic resistance （suitable for repeated steam sterilization）
　　
　　3. High rigidity in a wide range of temperature
　　
　　4. High impact strength, better impact strength than PSU
　　
　　5. Physiological laziness （applicable to food touch）
　　
　　6. High dimensional stability
　　
　　7. Anti high energy radiation function （gamma - and X-ray）
　　
　　8. Excellent electrical insulation function and dielectric function
