PSU Characteristics
Polysulfone (PSU) is a transparent, high-performance, ultra-stable polymer with a high service temperature. It has good impact and electrical properties and good resistance to inorganic acids and bases. Polysulfone also has superior hydrolytic stability against hot water and steam sterilization.
Polysulfone resists detergents and hydrocarbon oils well even at high temperatures under moderate stress levels. And it complies with the National Sanitation Foundation’s potable water standard up to 180 degrees F. Its characteristics include:
- Performs well in broad temperature range
Excellent hydrolytic stability- Good chemical resistance
- High impact resistance
- Superior electrical properties
- Performs well in high-temperature environments
Applications for Polysulfone
- Medical instruments
- Food processing equipment
- Aircraft instruments
- Electrical components
- Float switches
- Solenoid valve body
- Manifolds
