Material showcased: Ertalyte® PET-P
There are many different types of plastics, each offering an ideal solution for different challenges. The possibilities and applications are virtually endless. Lakwijk is here to guide you through the world of plastics. From time to time, we highlight a specific material. Today, that material is Ertalyte® PET-P.
ERTALYTE® PET-P
Ertalyte is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is produced from proprietary resin grades developed by Mitsubishi Chemical Advanced Materials. The material is characterized by its exceptional dimensional stability combined with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. These properties make Ertalyte particularly suitable for the manufacture of precision mechanical components that must withstand high loads and long-term wear conditions. Ertalyte has a continuous service temperature of 210°F (100°C), and its melting point is nearly 150°F higher than that of acetals.
Ertalyte offers excellent chemical resistance and wear performance. Due to its low moisture absorption, its mechanical and electrical properties remain virtually unaffected by humidity. It can be machined to very tight tolerances using standard metalworking equipment.
Ertalyte is available in a ‘Food Grade’ certified version and is therefore suitable for use in the food-processing industry. Lakwijk is fully familiar with this certification. Ertalyte is available in natural (white) and, upon request, also in black. The material is an excellent candidate for components used in food processing, machinery construction, and equipment manufacturing.
