Varilla de forma especial PPSU
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)
