PPSU (polyphenylsulfone) is a high-performance thermoplastic with excellent chemical resistance, high temperature resistance, and mechanical strength. It is made through a polymerization reaction of styrene and sulfonates, resulting in a high degree of stability in the chemical structure.PPSU is commonly used in demanding applications such as medical devices, aerospace, and industrial equipment.
Properties of PPSU Materials
1. Excellent chemical resistance: PPSU has good resistance to many chemicals such as acids, alkalis and solvents.
2. High Temperature Resistance: It can remain stable in high temperature environments, and the heat resistance temperature can reach over 180°C.
3. Good mechanical properties: high strength and toughness, even at high temperatures can maintain excellent physical properties.
4. Excellent hydrolysis resistance: no hydrolysis reaction occurs in moisture or humid environment, so it is suitable for applications that require long-term exposure to water.
5. Good molding properties: can be molded through a variety of processing methods (such as injection molding, extrusion, etc.) to adapt to the diverse manufacturing needs.
