Polyethylene Terephthalate (PET)


Textile Chips (Modified semi dull), has been improved to increase Spinning and texturizing speed.

Chemical composition:

Poly (ethylene terephthalate) copolymer from Pure Terephthalic Acid (PTA) and Ethylene Glycol (EG) and special comonomer.


Textile chips are mainly used in the production of polyester fibers and filaments, specially for microfilament.

         2)  'Color' determined after crystallization and grinding.

         3)  All presented parameters would be average of lab results.


Storage and Handling:
PET resin should be stored in a manner to prevent a direct exposure to sunlight and/or heat. The storage area should also be dry with relative humidity below 50% and temperatures preferably don’t exceed 50 ºC. STPC would not give warranty to bad storage conditions which may lead to quality deterioration such as color change, bad smell and inadequate product performance. It is advisable to process PET within 6 months after delivery.
