Overview of polybutylene terephthalate B Polybutylene terephthalate, also known as polytetramethyl terephthalate. The proper name is: br, abbreviated as B, B or, hereafter referred to as B. It is the condensation polymer of terephthalic acid and butanediol. It can be produced by the exchange method or the direct esterification method through polycondensation. The future development trend is the direct esterification method. B and B together are called thermoplastic polyester.
The B main chain is composed of a saturated linear molecule in which each repeating unit is a rigid benzene ring and a flexible fatty alcohol. The high geometric regularity and rigidity of the molecule give the polymer high mechanical strength and outstanding Resistance to chemical reagents, heat resistance and excellent electrical properties. There are no side chains in the molecule, and the structure is symmetrical, meeting the requirements of confidential stacking, so that this polymer has a high degree of crystallinity and a high melting point. The structure of the molecule determines B Has good overall performance.

: Good mechanical properties, high mechanical strength, good fatigue resistance and dimensional stability, small creep, these properties rarely change under high temperature conditions .
: The energy consumed in producing B is also the lowest among engineering plastics, which is of great significance in the current world-wide energy shortage.
: Excellent heat aging resistance, the enhanced temperature index reaches ~℃, in addition, the long-term outdoor aging resistance is also very good.
It has good solvent resistance and no stress cracking.
:B is easy to decompose when exposed to water, so be careful when using it in high temperature and high pressure environments.
: Easy to flame retardant, up to grade. Due to the good affinity of flame retardants, it is easy to develop reactive or additive flame retardant grades. Flame retardant products are widely used in the electronic and electrical industry.
: Excellent electrical properties, high volume resistivity and dielectric strength, excellent arc resistance, minimal hygroscopicity, and stable electrical properties in humid and high-temperature environments. It is ideal for manufacturing electronic and electrical parts. Ideal material.
:Easy to molding and secondary processing, easy to use ordinary equipment for injection molding or extrusion. Due to the fast crystallization speed, good fluidity, and lower mold temperature requirements than other engineering plastics, it only takes a few seconds to process thin-walled parts, and it only takes a few seconds for most parts
