Polyethylene terephthalate (PET) is famous as a resin for PET bottles.

PET has a long history and track record of use as a high-molecular weight compound, and is still expanding its scope of application in the areas of synthetic polyester fiber, polyester film, and PET bottles, etc.
In addition, reinforcing PET resin with glass fiber makes it possible to significantly improve mechanical characteristics and thermal resistance, and it has been used for a variety of applications.
