PPSU is an amorphous high-performance thermoplastic that occupies a distinct position in the high-performance plastics range. Where PEEK delivers the highest temperature resistance and chemical performance, and PEI excels in dielectric applications, PPSU is engineered for applications that demand repeated steam sterilization, superior toughness and biocompatibility.
As an amorphous thermoplastic, PPSU provides excellent hydrolysis resistance, stable dimensions and consistent performance in both wet and high-humidity environments. Its superior impact strength sets it apart from other high-performance plastics in the same temperature range, making it suitable for components subject to mechanical shock, drops or handling in clinical and industrial environments.
PPSU is available in two grades. The general grade covers industrial applications including plumbing components, aerospace parts, food and beverage processing equipment and membrane housings for water filtration.
Reliable performance at elevated temperatures with stable mechanical and dimensional properties
Withstands hundreds of autoclave cycles without loss of mechanical performance or dimensional change
Exceptional toughness and resistance to mechanical shock compared to other high-performance plastics in the same operating range
Stable properties in wet, humid and aqueous environments including repeated exposure to hot water and steam
PPSU MG is formulated for direct contact with human tissue and body fluids in medical and surgical applications
Consistent dimensions maintained across repeated sterilization cycles and varying operating conditions
High-Performance Engineering Plastics
Both general grade and medical grade available in 1250x620 mm format. General grade in thicknesses 10 to 55 mm. Medical grade in thicknesses 3 to 55 mm, including thinner sheet formats for medical component production.
Solid bars from 15 to 90 mm diameter in 1000 mm lengths in both grades. Wide colour range available across both variants.
Custom cut to your exact dimensions from standard sheet or bar stock in general or medical grade.
CNC-machined parts to your technical drawings in general or medical grade PPSU. Suitable for instrument housings, sterilization trays, fluid handling components and structural insulating parts.
PPSU MG is used for handles, housings and structural components of surgical and dental instruments that undergo repeated autoclave sterilization. Its biocompatibility and sterilization resistance make it a direct material specification in medical device manufacturing.
Used for reusable sterilization trays, instrument containers and cassettes in operating theatre and central sterilization unit environments where hundreds of sterilization cycles are required without material degradation.
PPSU MG is applied in endoscopic instrument components and housings where biocompatibility, chemical resistance to cleaning agents and sterilization resistance are simultaneously required.
General grade PPSU is used for plumbing fittings, valve components and fluid handling parts where hot water resistance, hydrolysis resistance and dimensional stability over long service life are required.
Applied in aerospace interior and structural components where high thermal stability, low flammability and toughness under mechanical stress are required within weight constraints.
Used for membrane housings, filter housings and water treatment components where resistance to aggressive cleaning chemicals, hot water and steam is required for long service intervals.
