PPSU is polyphenylsulfone. Makers sell it for aerospace, automotive, dental and medical uses, and cite its heat and chemical resistance. Its glass transition is typically 220 °C. It lies beyond the H2C: makers ask for 360–400 °C at the nozzle, a bed hotter than the H2C reaches and a heated chamber above its limit, though a maker says a standard nozzle suffices.
Partly documented Tensile modulus (XY), tensile strength (XY) and HDT at 0.45 MPa rest on 1 product each and tensile strength (Z), notched Charpy impact and price are not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials
Among the materials, PPSU has a high HDT at 0.45 MPa and a low elongation at break (XY): both are in the top or bottom quarter of the materials that publish them. The rest of its key properties sit in the middle half.
Against its alternatives, PPSU has the highest HDT at 0.45 MPa
How does it compare with what an engineer would buy instead?
- PPSU: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
- beyond the scale
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

Mechanical properties
Printed flat (XY), PPSU typically reaches a tensile strength of 55 MPa at a modulus of 2.31 GPa, and breaks at 3 % elongation. In bending, its flexural strength is typically 110 MPa at a flexural modulus of 2.21 GPa.

- a product
- middle half and median
One mark per product on each property's scale (zoomed where its products sit close together, as its label says); the band is the middle half of the products the median counts, and the line the median.
Hover or select a product to find it in every figure; its name opens its card on the Products page.
