The major products of the PBT Office are polybutylene terephthalate (PBT) and polyethylene terephthalate (PET).
PBT resin is the condensation product of terephthalic acid and 1,4-butanediol (14BG). PBT features a quick crystallization speed and a short molding cycle. A "compound" made up of PBT, glass fibers, and fire retardant is used to make parts for the electrical, electronics, and automotive fields.
PBT resin is sold by Mitsubishi Engineering Plastics with the brand name "NOVADURAN." For details of NOVADURAN see Mitsubishi Engineering Plastics web page.
PET resin is the condensation product of terephthalic acid and ethylene glycol, and is used as a material for film, sheet or bottles. Although PET is a crystalline resin, a transparent product can be obtained without crystallizing if rapid cooling from the molten state is carried out.
The rest is sold by Mitsubishi Chemical with the brand name of a "NOVAPEX."
