Overview
PSU is the standard grade of the PSU family in the high-performance plastics group. It is used in applications such as medical trays and sterilisation containers, dairy and food-processing parts, membrane and filter housings. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.
Typical properties
| Property | Typical value |
|---|---|
| Density | 1,24 g/cm³ |
| Glass transition (Tg) | 185–190 °C |
| Tensile strength | 70–75 MPa |
| HDT (1.8 MPa) | 170–175 °C |
Tensile strength is measured to ISO 527, melt flow rate to ISO 1133, heat deflection temperature to ISO 75 (1.8 MPa); flammability class per UL94. Depending on supplier and grade, values can fall outside this range.
Applications
- Medical trays and sterilisation containers
- Dairy and food-processing parts
- Membrane and filter housings
- Hot-water meter and valve parts
Documents
The supplier's technical data sheet (TDS) and safety data sheet (SDS) for PSU are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
