Ertalyte® PET-P is an unreinforced, semi-crystalline thermoplastic polyester (PET-P) engineering plastic renowned for its outstanding mechanical properties, dimensional stability and wear resistance. It is frequently employed in the manufacture of high-load, high-precision industrial components.
Key Properties and Advantages:
Superior Mechanical Properties: Exhibits high strength, rigidity and hardness while maintaining good toughness, with mechanical strength and stiffness surpassing many conventional materials.
Outstanding Wear Resistance and Low Friction: Wear resistance rivals or exceeds nylon, featuring a low and stable coefficient of friction, making it highly suitable for wear-resistant components such as plain bearings and gears.
Exceptional Dimensional Stability: Exhibits minimal dimensional change under various environmental conditions, outperforming polyoxymethylene (POM), making it an ideal choice for precision components.
Good Chemical and Environmental Resistance: Resists weak acids and organic solvents well, with extremely low water absorption, maintaining its electrical and mechanical properties unaffected by moisture.
However, note that it is not resistant to prolonged immersion in hot water or strong alkaline environments.
Food and medical grade compliance: Ertalyte® PET-P (natural/white) meets FDA food contact standards. The white variant additionally complies with USDA, 3A dairy, and Canada AG standards, ensuring safe use in food processing equipment and medical components.
Additional properties: Offers excellent electrical insulation, radiation resistance (gamma and X-rays), and stain resistance.
Common Forms and Applications:
Ertalyte® PET-P is typically supplied as sheets, rods, or custom components, available in natural (white) and black colours.
Its applications span diverse sectors, including:
Food processing equipment: Such as hamburger moulds, conveyor belt components, manifolds, etc., owing to its ease of cleaning and corrosion resistance.
Industrial machinery components: Such as high-load plain bearings, pump parts, housings, container plugs, and steering wheels for the textile industry.
Electronics and medical equipment: Leveraging its insulating properties and physiological inertness for insulating components and parts in medical testing apparatus.
Related Product Series:
The Ertalyte® range also includes Ertalyte® TX, a modified version incorporating solid lubricants. Specifically engineered for bearing applications, it offers a lower coefficient of friction and higher pressure-velocity (PV) ratings, typically appearing in a light grey hue.
