PET-P / Ertalyte®

PET-P is an unreinforced, semicrystalline thermoplastic polyester based on polyethylene terephthalate. It is a high-strength product, has excellent dimensional stability and resists wear and the effects of moderately acidic solutions. A high melting point enables PET-P to retain significantly more of its original strength than nylon or acetal, making it suitable for the manufacture of precision mechanical parts. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture.

In addition, PET-P has good resistance to chemicals and abrasion and can be machined to exacting detail on standard metal-working equipment.

PET-P Ertalyte® is FDA compliant in natural and black. Natural PET-P Ertalyte® is also USDA, 3A-Dairy and Canada AG compliant. PET-Ertalyte® is an excellent candidate for parts used in the food processing and equipment industries.

Ertalyte® PET-P

Ertalyte® PET-P is a thermoplastic polyester based on polyethylene terephthalate that has excellent wear resistance, low coefficient of friction, high strength, and resistance to moderately acidic solutions. It also is more rigid and provides better thermal performance than nylon or acetal.

Ertalyte® TX

Ertalyte® TX is an internally lubricated thermoplastic polyester. It provides excellent wearability and a level of inertness that surpasses nylon and acetal. The uniform distribution of solid lubricant throughout the product results in minimal wear and friction, outperforming unmodified polyesters such as PET or PBT. Ertalyte® TX performs exceptionally well under high-pressure and high-velocity conditions and is well suited for uses involving soft metal and plastic mating surfaces.
