Product Description

Polyester chips, also known as polyethylene terephthalate chips, polyethylene terephthalate resin, abbreviated as PET Chips or PET resin, usually refer to flaky particles processed from PTA and MEG. PET Chips is a high polymer, which is derived from the dehydration condensation reaction of ethylene terephthalate. Polyester chips are developed into different types with vary composite propotions which have different functions.

Textile-grade polyester chips are used for making the Polyester Filament yarn like POY, FDY and Staple fibre. The Yarn grade (Textile grade) chips are available in Semi Dull and Bright PET Chips.

PET Chips used in Textile Industry is also known as Fibre grade PET chips, filament grade PET chips or textile grade PET chips. Textile grade PET Chips are used for making Polyester Filament yarn like POY, FDY and Staple fibre used widely in the Textile industry.

The process of making PET Chips consists of mixing a thermoplastic polyester-resin material with an alumina tri-hydrate (ATH) filler and with a pigment, if desired, in a heated extruder to produce a continuous stream of thermoplastic agglomerate. This product is allowed to cool, then it is cut, ground and screened to a predetermined size, as required to meet the size characteristics of the desired resin-chip product.
