That's 10,000tons a year.-150,000. Self-lubrication, low friction coefficient,but large volume resistance, dielectric loss. The disadvantage isthe notch impact intensity is low, the molding shrinkage rate isbig. Therefore, most of the glass fiber reinforced or inorganicfiller modification, its tensile strength, bending strength can beincreased by more than one time, thermal deformation temperature isalso greatly increased. It can work at 140 °C for a long time. TheLongitudinal and transverse shrinkage of glass fiber reinforcedproducts are not consistent, and the products are easy to warp.Non-flammable, burning without liquid flow, leaving the flame in 5seconds after extinction, similar to PC. POLYBUTYLENE terephthalate(PBT) is a kind of Thermoplastic used in different industries. Itis usually mixed with some additives or other plastics. Dependingon the proportion of the additives, it can be made to differentspecifications. Because PBT has heat resistance, weatherresistance, resistance, good electrical properties, small waterabsorption, good luster, widely used in electronic appliances,automotive parts, machinery, household products, etc. , and PBTproducts and PPS, PC, POM, PA are known as five General EngineeringPlastics. The shutdown time of PBT was less than 30 min, and thetemperature could be reduced to 200 °C. Long-term shutdown afterthe re-production, to empty the barrel of material, and then addnew material to carry out normal production. 4 The post-treatmentof products does not need to be carried out under normalcircumstances, if necessary, the treatment at 120 °C for 1 ~ 2hours. Poly (butylene terephthalate) is a crystalline thermoplasticengineering plastic obtained by polymerization of dimethylterephthalic acid 1,4-Butanediol 1,4-Butanediol. The chemicalstructure of PBT was studied by Celanese company in the early1970s, because the chain of PBT resin is easy to bend because ofthe increase of the chain length, so the glass transfer temperatureis lower than that of PET and the crystallization rate is faster,and listed under the name Celanex. Poly (butylene terephthalate) ,also known as poly (tetramethyl terephthalate) . English name:Polybutyleneterephthalate. PBT, or PMT for short, is apolycondensation of parabens and 1,4-Butanediol acid. It can beprepared by transesterification or direct aliphaticpolycondensation. The development trend in the future is directesterification. PBT is known as thermoplastic polyester togetherwith PET. 40-60s for most parts. A, electronic appliances:connector, switch parts, household appliances, spare parts, smallelectric cover or (heat resistance, flame resistance, electricalinsulation, Molding Processing) ; External Parts: There are mainlyAngle Geshan, engine vent cover, etc. ; internal parts: There aremainly endoscopic brace, wiper support and Control System Valve;Automotive Electrical Parts: Automotive Ignition Coil Capstan andvarious electrical connectors. (the amount of PBT used inautomobiles is less than that of nylon, polycarbon andPolyformaldehyde, but with the appearance of low-warpage PBT, thePBT must be dried for about 3 hours at 110 ~ 120 °c beforeinjection molding, the molding temperature is 250 ~ 270 °C, and themold temperature is 50 ~ 75 °C. Because the material from themelting state after cooling, it will immediately solidificationcrystallization, so its cooling time is shorter; if the nozzletemperature control is not appropriate (low) .台湾长春PBT6730
