Introduction
Polyphenylsulfone (PPSU) is a high-performance thermoplastic known for its exceptional thermal stability, chemical resistance, and mechanical strength. It is widely used in applications that demand durability under extreme conditions, including repeated sterilization and high-temperature exposure. Insights from Stratview Research indicate that the global polyphenylsulfone market was valued at USD 281.77 million in 2022 and is projected to grow at a CAGR of 9.18% during 2023–2028, reaching USD 480.1 million by 2028, reflecting strong market momentum.

Key Features
PPSU offers a high heat deflection temperature, excellent hydrolytic stability, inherent flame retardancy, and low moisture absorption. These features ensure long service life, dimensional stability, and consistent performance in harsh operating environments, making it superior to many conventional engineering plastics.
