What Are Polyester Chips?

Polyester chips usually refer to the polyester raw materials produced by polymerization are generally processed into flake particles of about 4*5*2 mm. The technological route of polyester production includes direct esterification method (PTA method) and transesterification method (DMT method).

The PTA method has the advantages of low raw material consumption and short reaction time, and has become the main process and preferred technical route of polyester since the 1980s. Large-scale production lines are continuous production processes, while semi-continuous and intermittent production processes are suitable for medium and small production plants. The use of polyester now includes fibers, various containers, packaging materials, films, films, engineering plastics and other fields.

Polyester chip scientific name: polyethylene terephthalate, English abbreviation: PET is polymerized by purified terephthalic acid (PTA) and ethylene glycol (EG). It is used for the packaging of various beverages, especially carbonated beverages), polyester film (mainly used for packaging materials, films and tapes, etc.) and polyester for chemical fibers.
