PET is highly sensitive to moisture at high temperatures and exhibits excessive warpage when reinforced with glass fibers. The promotion of crystallinity is achieved through adding nucleating agents and crystal growth accelerators. Crystalline moldings exhibit high modulus, gloss, and heat distortion temperatures. Warpage is minimized by the addition of particulate fillers such as mica. When low mold temperatures are used, transparent moldings can be obtained with unfilled PETs.

Polyethylene terephthalate (PET) has excellent chemical resistance and barrier properties, good strength, rigidity, fatigue endurance, and abrasion resistance.

Runners and Gates of PET Injection Mold All conventional types of gates can be used. Gates should be 50–100% of the part thickness.

Chemical and Physical Properties PET is an aromatic polyester produced from the polymerization of either terephthalic acid (TPA) or dimethyl ester terephthalic acid (DMT) and ethylene glycol (EG). The glass transition is approximately 165°C [330°F] and the material crystallizes over a temperature range from 120°C–220°C [248°F–428°F].

Typical Applications of Polyethylene terephthalate (PET) Automotive – mirror backs – grille supports – head lamp reflectors – alternator housings Electrical applications – motor housings – electrical connectors – relays – switches – microwave oven interiors Industrial applications – furniture chair arms – pump housings – hand tools – PET bottles and containers
