PET-P Plastic

PET P is a high-quality wear-resistant engineering plastic material with the chemical name polyethylene terephthalate. It is a crystalline material, a member of the polyester family of plastics, which should not be confused with the clear, amorphous version used to make bottles for carbonated drinks. PET exhibits particularly good dimensional stability and is available in a range of grades and forms to suit many applications.

Machinability

While not as fine as Acetal, the machinability of the above grades of PET is excellent. As with all plastic materials, experience has shown that extra care must be taken with larger diameters, especially in the colder months when plastic materials lose some of their toughness and have less resistance to machining stresses. It’s important that these materials are not machined while in a chilled condition. Full machining instructions are available on request.

Chemical Resistance

PET has acceptable resistance to weak & diluted acids at 20°C. Contact with alkalis is to be avoided, as is long-term contact with water above 70°C because the material is sensitive to hydrolysis.

Typical Applications

Commercial applications for this engineering material include:
