PPSU particles gray

PPSU is an amorphous, high-performance thermoplastic. It has better impact and chemical resistance than PSU and PEI. PPSU has been proven to have excellent hydrolysis resistance, surpassing other amorphous thermoplastics, in autoclave failure tests. In fact, PPSU can be placed in an unlimited number of steam sterilization environments, and high-pressure steam is widely used to sterilize medical components, making PPSU a good choice for medical devices.

Main characteristics and advantages of PPSU:

◆High temperature resistance (180°C)

◆High hardness

◆Good chemical compatibility

◆High impact strength

◆High dimensional stability

◆Good electrical insulation

◆Excellent hydrolysis resistance (suitable for repeated steam sterilization)

◆Excellent dielectric properties

◆Excellent resistance to high energy radiation (gamma rays and X-rays)
