PSF

Polysulfone (PSF) is an engineering thermoplastic known for its high stiffness, thermal stability, and transparency, making it suitable for demanding applications requiring both mechanical strength and heat resistance. It is widely used in aerospace components, medical devices, automotive interiors, and transparent housings where long-term performance at elevated temperatures is critical. PSF is chosen over commodity polymers when superior dimensional stability, chemical resistance, and retention of properties in high-temperature environments are necessary, though it typically costs more and offers lower elongation than ductile alternatives.
