Antioxidant, UV Absorber, Optical Brightener, Pigment for PET

PET is an abbreviation of Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), which is the most common thermoplastic polymer resin of the polyester family.

The main application includes fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.

Things to know when choosing pigment for PET

The thermal requirements for pigments which are targeted for PET melt extrusion are particularly severe.  Are only tolerated by very few polycyclic pigments, primarily by representatives of the quinacridone, copper phthalocyanine, naphthalene tetracarboxylic acid, and perylene tetracarboxylic acid series.

In the case of polyester, the newer coloration technologies are carried out to advantage with dyes which are melt-soluble, sufficiently heat resistant, and sublimation, proof during spinning.
