Polysulfone is an amorphous thermoplastic with natural transparency. In most cases the plastic is suitable for continuous use up to 149°C (300°F). PSU is also resistant to degradation by gamma or electron beam radiation.
We offer two grades of PSU through our injection molding service:
Udel P-1700: High resistance to mineral acids, alkali and salt solutions. It also possesses good resistance to detergents and hydrocarbon oils.
Udel P-3703: A high-flow grade of PSU that fills thin walls well. Can be more susceptible to cracking than P-1700 when in harsh environments.
Polysulfone Injection Molding Applications
PSU is a good material choice for molded parts that will have to endure high temperature environments. Its chemical resistance and compliance with gamma sterilizability requirements also lends itself well for medical applications.
PSU is often used for the following parts:
- Medical devices and components
- Appliances components
- Dental parts
- Surgical instruments
- Industrial applications
- Electrical parts
