PPSU rods of various specifications

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 high-pressure steam sterilization failure tests. In fact, PPSU can be placed in a steam sterilization environment for an unlimited number of times, 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)
