What Is PPSU Material?
PPSU stands for Polyphenylsulfone and is a high-performance, amorphous thermoplastic.
PPSU has exceptional thermal stability, chemical resistance, and toughness. PPSU belongs to the polysulfone plastics and offers the highest performance among sulfone polymers.

PPSU Stock Shapes
We offer high-quality PPSU in a range of stock shapes, ideal for precision CNC machining across medical, aerospace, and industrial applications.

Rod
PPSU rod stock is the most commonly used form for CNC turning and milling. Rod stock comes in various diameters and is ideal for producing precision components.

Sheet
PPSU sheet and plate provide flat, stable surfaces for milling or routing large parts. PPSU sheets are used in enclosures and fluid devices.

Tube
PPSU tubing comes in pre-determined sizes and is used in applications where internal flow channels and insulation are required. It is cost-effective for hollow part applications.

Pre-cut Blanks
For large volume PPSU machined parts, we offer custom-cut blanks or near-net shapes to optimize machining time.
