Frequently Asked Questions
Can these PPSU rods be sterilised in an autoclave?
Yes, PPSU is designed to withstand repeated steam sterilisation and autoclaving at high temperatures without significant loss of mechanical properties, making these rods suitable for reusable medical and laboratory components.
Are the rods suitable for machining into fine, precision components?
Yes, the material offers good dimensional stability and machinability, allowing it to be turned, milled and drilled into detailed parts with tight tolerances when using appropriate tooling and machining parameters.
How do I choose the right diameter and length for my application?
Select a diameter that provides sufficient wall thickness or strength after machining your final component geometry, then choose the nearest standard length (1000 mm, 2000 mm or 3000 mm) that minimises offcuts while providing enough material for your production or prototyping needs.
