Description
PPSU (Polyphenylensulfone) is an amorphous material known for its superior impact and hydrolysis resistance compared to PSU. The characteristics of this high-performance material include:
- High strength and rigidity
- Very high impact strength, even at low temperatures
- Excellent dimensional stability
- Outstanding chemical resistance
- High resistance to various types of radiation
- Good sterilization capability
The exceptional notch impact strength is preserved even after heat aging, making it ideal for demanding environments.
Typical applications for this PPSU rod include components for microwave ovens, hair dryers, insulators, humidifiers, and a variety of uses in the food and medical industries.
