Overview
PESU is the standard grade of the PES / PESU family in the high-performance plastics group. It is used in applications such as membranes and filtration products, electrical parts in hot environments, lamp and lighting reflectors. 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 | 1,37 g/cm³ |
| Glass transition (Tg) | 225 °C |
| Tensile strength | 85–90 MPa |
| HDT (1.8 MPa) | 200–205 °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
- Membranes and filtration products
- Electrical parts in hot environments
- Lamp and lighting reflectors
- Aerospace composite matrix
Documents
The supplier's technical data sheet (TDS) and safety data sheet (SDS) for PESU are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site.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.
