PET (Polyethylene terephthalate), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fibre for engineering resins. Due to its good creep strength, low moisture absorption and outstanding dimensional stability, PET is extremely well suited for applications where complex parts combined with the tightest requirements in dimensional accuracy and surface quality are needed. PET also exhibits very good chemical resistance characteristics.
