Polyethylene Terephthalate (PET)

Semi-crystalline injection molded PET is a polymer which offers the right solution for a variety of special applications. For general injection molding applications, well-crystallized parts are preferred to minimize post-molding shrinkage and deformation. This objective is achieved by the use of appropriate nucleating and plasticizing agents, leading to fast-cycling, typically glass- reinforced and/or mineral-filled materials. PET compounds of this type offer high strength, good impact resistance, high temperature tolerance and the ability to withstand a broad range of chemicals.  

Typical applications tend to be either in electrical parts, where the excellent insulation properties of the base resin are important, or in large autobody parts such as grille opening panels, where high filler loadings provide high stiffness and creep resistance at elevated temperatures.

The Impet® PET products from Ticona includes a range of general-purpose glass- reinforced and mineral-filled grades.
