        Frequently asked questions (FAQs)

        All three belong to the high-performance sulfone polymer family but offer different balances of properties. PES provides particularly strong high-temperature performance alongside chemical resistance and excellent mechanical properties. PPSU stands out for exceptional toughness, impact resistance, and hydrolytic stability, making it particularly valuable for repeated steam sterilization. PSU provides an excellent balance of strength, stiffness, transparency, thermal resistance, and hydrolytic stability for medical, water management, and industrial applications.

        PARYLS® PPSU/PSU is a modified polymer system combining PPSU and PSU technologies. It provides a tailored balance of toughness, thermal performance, chemical resistance, and hydrolytic stability for applications where the property profile of standard PPSU or PSU may not provide the optimum solution.

        Selected PARYLS® sulfone polymers combine high-temperature resistance with excellent hydrolytic stability, toughness, and chemical resistance. PARYLS® PPSU can withstand repeated steam sterilization at temperatures up to 134°C, making it particularly attractive for reusable medical devices, sterilization equipment, and surgical and dental instruments.

        Yes. Excellent hydrolytic stability is an important characteristic of the PARYLS® portfolio. Selected PPSU and PSU materials can maintain their properties during prolonged exposure to hot water, making them suitable for applications such as plumbing fittings, faucets, valves, water treatment systems, and fluid handling components.

        Selected PARYLS® grades are suitable for food-contact applications and can provide excellent resistance to heat, repeated washing, chemicals, and hydrolysis. Applications can include food service equipment, cookware, kitchen appliances, reusable containers, and infant feeding products. Grade-specific regulatory compliance should always be confirmed for the intended application and market.

        Sulfone polymers offer inherent flame-resistant characteristics without relying solely on the addition of conventional flame-retardant systems. Selected PARYLS® grades are therefore particularly attractive for electrical, electronics, aerospace, and other applications where both high-temperature performance and flame resistance are important.

        The optimum material depends on the complete application environment, but PARYLS® PES provides particularly strong high-temperature capabilities, with selected grades offering heat deflection temperatures up to 205°C and long-term temperature ratings up to 180°C. PPSU also provides excellent thermal performance alongside exceptional toughness and hydrolytic stability.

        Omya Performance Polymer Distribution helps customers compare the thermal, mechanical, chemical, hydrolytic, processing, and regulatory requirements of their application against the different PARYLS® technologies.
