THERMOPLASTIC POLYESTER (SATURATED)

Thermoplastic polyesters are highly crystalline, hard, strong and extremely tough. They form a family of polyesters in which the polyester backbones are saturated and hence unreactive. The most common commercial types are: PET (polyethylene terephthalate) produced by polycondensation of ethylene glycol with either dimethyl terephthalate or terephthalic acid; and PBT (polybutylene terephthalate) produced by the reaction of DMT with 1,4 butanediol.

Typical Applications:
X-ray film, magnetic tape (audio, video and computer); packaging; metalized film, strapping and labels.
