PSU and PPSU Plastics

Polysulfone (PSU) and Polyphenylsulfone (PPSU) are high-performance thermoplastics known for their toughness and stability in high-temperature applications. PSU offers excellent mechanical and chemical resistance, while PPSU provides even greater impact strength and thermal stability. These materials are ideal for applications requiring long-term performance in harsh environments, and are frequently used in medical, aerospace, and food industry applications.
