PET-P (Polyethylene Terephthalate)

Plastic

PET-P, also known as hard PET, is a strong, dimensionally stable engineering plastic with excellent sliding and wear properties. The material is particularly suitable for precision components that deform very little, even under prolonged load. PET-P is wear-resistant, moisture-resistant, and easily machinable, making it widely used in technical applications where dimensional accuracy is crucial.
Well-known trade names for PET-P include Ertalyte®, Arnite®, Sustodur®, and Tecapet®. These high-quality PET plastics are often used in machine building and the food industry.

Properties of PET-P

High dimensional stability and accuracy
Low coefficient of friction and good wear resistance
High mechanical strength and stiffness
Resistant to moisture and hydrolysis
Good chemical resistance to oils, fats, and solvents
Food-safe (FDA-compliant for certain grades)
Low creep, even under continuous load
Good electrical insulating properties
Easy to machine and finish

Thanks to this balance of mechanical strength, stability, and machinability, PET-P is a popular choice for precise, wear-resistant components in demanding industrial applications.

Frequently Asked Questions about PET-P

How does PET-P differ from standard PET?

PET-P is a technically optimized grade with higher dimensional stability and wear resistance than standard PET, which is commonly used for packaging.

Is PET-P suitable for food-contact applications?

Yes, many PET-P grades (e.g., Ertalyte®) are FDA-certified and safe for food contact.

Can PET-P be milled or machined?

Absolutely, PET-P machines exceptionally well, yielding minimal stresses and high dimensional accuracy.

How moisture-resistant is PET-P?

PET-P has low moisture absorption and retains its mechanical properties even in humid environments.

What are alternatives to PET-P?

For higher-temperature use: PEEK. For lower cost with slightly less stability: POM.

Is PET-P electrically insulating?

Yes, it boasts good dielectric properties and is often used as an electrical insulator.

Can PET-P be used outdoors?

Prolonged UV exposure can cause discoloration and aging. For exterior use, choose UV-stabilized grades.

What are the most common PET-P uses?

Precision machine parts such as sliding blocks, bearings, and gears where wear resistance and stability are critical.
