Material Focus: PET

April 29, 2020

Polyethylene terephthalate (PET) is the most common thermoplastic polymer resin of the polyester family, and is used in fibers for clothing, containers for liquids and foods, thermoforming, and manufacturing.

Today we are going to take a look at the type of PET we use here at Aeromat Plastics, which comes in solid machinable shapes.

What is PET?

PET is a strong, hard, and dimensionally stable material that absorbs very little water. It has good gas barrier properties and good chemical resistance except to alkalis (which hydrolyse it). PET's crystallinity varies from amorphous to fairly high crystallinity; it can be highly transparent and colorless, but thicker sheets are usually an opaque white.

What is PET used for?

In the world of machining, PET is a cost effective, dimensionally stable material that can be used in a wide variety of applications. From components inside scientific equipment, to pulleys on industrial machines, PET is a versatile material that can be used in almost any industry.

Is it FDA approved?

Yes, in fact, it is the most widely used material for plastic bottles and food storage containers.
