PET
Polyethylene terephthalate, commonly known as PET, is a thermoplastic material. PET is used in areas exposed to moisture and where high dimensional stability and strength are required. These properties allow it to be used in precision components.
In terms of chemical resistance, PET, compared to PA6 and POM, exhibits greater resistance to acids but less resistance to alkalis.
PET is available in transparent, white, frosted, and anti-reflective sheets. It is also available in a UV-stabilized version.
Properties:
High ductility and stiffness
Brittle at low temperatures
High strength and hardness
Abrasion resistant
Thermally stable, low coefficient of thermal expansion
Dimensional stability
Sensitive to hydrolysis
Examples of applications:
Sliding components (bearing bushings, rollers, slides)
Electrical insulating components
High-gloss components
Food contact components
Cold water contact components
