PBT polymerization Unit

Poly (terephthalic acid) butyl diol ester , the English name Polybutylene terephthalate (PBT), belonging to the polyester series, is made from 1.4 butyl alcohol (1.4-butylene glycol) and terephthalic acid (PTA) or terephthalic acid ester (DMT) esterification, For milky translucent to opaque, crystalline thermoplastic Polyester resin 。 Together with pet collectively referred to as thermoplastic polyester, or saturated polyester.

Device Introduction:

Continuous PBT Equipment: The use of three-kettle process, PTA routes, capacity of 30-500 tons/day, Advantage: Low temperature, low molar ratio, mild reaction , low consumption, energy saving, melt fluidity is good, Maintain reasonable material consumption at different reaction stages;

Intermittent PBT device: The use of two-kettle process, PTA or DMT route, production capacity of 3-40 tons/day, advantages: catalysts and additives can be added at low temperature, esterification at low temperature or normal reaction temperature continuous feed, easy to control, safe and reliable;

THF recovery device: The use of filler tower for recycling, the purity of up to 99.99%.
