Introduction to PBT:

Polybutylene terephthalate, also known as polytrimethylene terephthalate. English name; Polybutyleneterephthalate Referred to as PBT PBTP or PTMT, which is a polycondensate of benzoic acid with 1,4-butanediol. Can be transesterification or direct lipidification by polycondensation and the future development trend for the direct esterification production. PBT and PET together are known as thermoplastic polyesters.

Features of PBT:

⒈ excellent mechanical properties, high mechanical strength, fatigue resistance and dimensional stability. Creep is also small, these properties in the high temperature conditions are rarely changed.

⒉ production of PBT is the lowest energy consumption of engineering plastics, which for the world's energy shortage situation, has a very important significance.

⒊ excellent heat aging resistance, enhanced UL temperature index reached 120 ~ 140 ℃, in addition, outdoor long-term aging is also very good.

⒋ good solvent resistance, no stress cracking.

⒌PBT easy flame retardant, up to UL94V-0 level, due to good compatibility with flame retardants, so easy to develop reactive or additive type of flame retardant grade. Flame retardant products in the electrical and electronic industry has been widely used.

⒍PBT in high temperature, high humidity environment easy to break down the water, the use of caution.

⒎ excellent electrical properties, volume resistivity and dielectric strength, excellent arc resistance, moisture absorption is extremely small, in the wet and high temperature environment, but also to maintain electrical stability, is to create electronic, electrical parts of the ideal material.

⒏ easy to shape and secondary processing, easy to use ordinary equipment injection or extrusion. As the crystallization speed, good fluidity, mold temperature than other engineering materials require low, in the processing of thin-walled parts only a few seconds, only 40-60s for large parts can be.

PBT applications:

Electronic appliances: connectors, switch parts, household appliances, parts parts, small electric cover (heat resistance, flame retardant, electrical insulation, molding processing);

Auto parts: Outer parts: Mainly have corner Geshan, engine exhaust hole cover; door handle, bumper, distribution plate cover, fender, wire cover, wheel cover, etc .; internal parts: Mirror staircase, wiper bracket and control system valves; electrical parts: car ignition coil twister and a variety of electrical connectors, and so on.
PBT for the number of cars is less than nylon, polycarbonate and POM, but with the emergence of low warpage PBT, the future will be in the automotive parts to get more applications).

Mechanical equipment : video tape recorder belt drive shaft, electronic computer hood, mercury lampshade, electric iron cover, baking machine parts and a large number of gears, cams, buttons, electronic table shell, camera parts (with heat, Request) and so on.

Industrial parts: OA fan, keyboard, fishing tackle, parts, shade, and so on.
