PPSU products
PPSU is a type of amorphous, high-performance thermoplastic. Compared to PEI and PEI, PPSU exhibits superior
impact strength and chemical resistance. High-pressure steam sterilization tests have proven that PPSU has
superior hydrolysis resistance to other amorphous plastics. In fact, PPSU can withstand millions of
high-pressure steam sterilizations, making it a very good choice for medical applications.
The main advantages of PPSU
- High temperature resistance
- High hardness
- Good chemical compatibility
- Good impact resistance
- Good dimensional stability
- Good electrical insulation
- Good hydrolysis resistance
- Excellent resistance to high-energy radiation (γ-ray and X-ray)
- Good dielectric properties
