Ertalyte PET-P is a modified polyethylene terephthalate (PET) grade engineered for demanding industrial applications that require outstanding sliding and wear performance. Its inherently low moisture absorption and high dimensional stability make it a reliable choice for close-tolerance parts.
With a consistently low coefficient of friction of 0.2, high tensile strength of 90 MPa, and a service temperature envelope from -20 °C to 100 °C, this material outperforms many general-purpose engineering plastics in dry-running and lubricated contacts. Its medium chemical resistance and low thermal expansion further broaden its utility.
Dotmar supplies Ertalyte PET-P as fully traceable stock shapes, backed by decades of local technical support and processing expertise. Choosing Dotmar ensures you receive genuine Ertalyte material supported by dependable data and fabrication capability.
Key Features
