Kimya PPSU-S is a 3D printing filament made from polyphenylsulfone (PPSU), an amorphous thermoplastic in the polysulfone family. Known for its high glass transition temperature and low moisture absorption, PPSU-S offers excellent resistance to heat and chemicals. This makes it an ideal choice for technical applications across sectors such as automotive, oil and gas, chemical processing, and low-volume injection molding. Kimya PPSU-S delivers high-performance results where strength, thermal stability, and chemical durability are critical.
• Flame retardant.
• Easy to print.
• Low Moisture Absorption.
