PPSU bridges the gap between PSU/PES and PEEK — high temperature, transparent or natural amber color, repeated sterilization without crazing. Ideal for medical sterilization trays, dental tools, and high-temperature handling components.
All SKUs are made-to-order from our own UHMWPE / HDPE / nylon production line. Send your DWG / DXF / PDF / STEP — we quote within 24 hours, MOQ from 1 piece.

Hospital sterilization service moved from polycarbonate trays to PPSU after 6-month brittleness test.
Read case →Dental instrument manufacturer chose PPSU handles for their 5x autoclave cycle life vs PC.
Read case →PPSU costs ~⅓ of PEEK and delivers full autoclave service for tray applications. PEEK is reserved for parts that also need mechanical strength at temperature (bearings, gears, threads under load).
It's translucent amber — light passes through but it's not optical-clear. For optical clarity at high temperature consider PEI (Ultem) or quartz instead.
