Stress crackingresistance, excellent wear resistance, chemical corrosionresistance, low-temperature impact strength, easy processing andgood finishing, mainly used in car bumpers, car chassis, panels andmotorcycle panels. Looking back to the past few years, the world'smajor PBT production companies are mainly concentrated in theUnited States, Western Europe, Japan and South Korea. A few yearsago, according to Kline & Co's statistical analysis, GE Plastics isthe world's PBT producers, production capacity of 140,000 tons peryear, in the period around 2004, the company already accounted for24.1 percent of the world's total production capacity. At the time,Ticona and dupont were the second and third producers of PBT, withproduction capacities of 80,000 and 75,000 tonnes per year,respectively, its share in the world's total productive capacitywas 13.8% and 12.0% , respectively. BASF, Teirenburi Plastics andBuyer are not far behind.
That's10,000-150,000 tons per year. Self-lubricating, low frictioncoefficient, but large volume resistance, dielectric loss. Thedisadvantage is the low impact strength of the gap, moldingshrinkage. Therefore, most of the glass fiber reinforced orinorganic filling modification, its tensile strength, bendingstrength can be increased by more than one time, thermaldeformation temperature is also greatly increased. It can workunder 140 ° C for a long time, and the longitudinal and transverseshrinkage rates of glass fiber reinforced products are notconsistent, so the products are easy to warp. Non-flammable, noliquid flow when burning, leaving the flame extinguished within 5seconds, (similar to PC) . PBT is a Thermoplastic, suitable for useby different manufacturers, usually with some additives, or withother plastics, with different proportions of additives, can bemade of different specifications of products. Because PBT has goodheat resistance, weather resistance, electrical properties, waterabsorption, good luster, widely used in electronic appliances,automotive parts, machinery, household goods, etc. , and PBTproducts and PPS, PC, Pom, PA and so on are collectively known asthe five engineering plastics. 3 the shutdown time of PBT treatmentis less than 30 minutes, and the shutdown time can be reduced to200 ° C. When reproducing after long-term shutdown, the material inthe cylinder should be emptied and new material should be added inorder to carry out normal production. 4 the post-treatment of theproducts does not need to be carried out under normalcircumstances, and if necessary, it needs to be treated at 120 ° Cfor 1 ~ 2 hours. Polybutylene terephthalate is a crystallinethermoplastic engineering
