Stress cracking resistance, excellent wear resistance, chemical corrosion resistance, low-temperature impact strength, easy processing and good finishing, mainly used in car bumpers, car chassis, panels and motorcycle panels. Looking back to the past few years, the world's major PBT production companies are mainly concentrated in the United States, Western Europe, Japan and South Korea. A few years ago, according to Kline & Co's statistical analysis, GE Plastics is the world's PBT producers, production capacity of 140,000 tons per year, in the period around 2004, the company already accounted for 24.1 percent of the world's total production capacity. At the time, Ticona and dupont were the second and third producers of PBT, with production capacities of 80,000 and 75,000 tonnes per year, respectively, its share in the world's total productive capacity was 13.8% and 12.0% , respectively. BASF, Teirenburi Plastics and Buyer are not far behind.
That's 10,000-150,000 tons per year. Self-lubricating, low friction coefficient, but large volume resistance, dielectric loss. The disadvantage is the low impact strength of the gap, molding shrinkage. Therefore, most of the glass fiber reinforced or inorganic filling modification, its tensile strength, bending strength can be increased by more than one time, thermal deformation temperature is also greatly increased. It can work under 140 ° C for a long time, and the longitudinal and transverse shrinkage rates of glass fiber reinforced products are not consistent, so the products are easy to warp. Non-flammable, no liquid flow when burning, leaving the flame extinguished within 5 seconds, (similar to PC) . PBT is a Thermoplastic, suitable for use by different manufacturers, usually with some additives, or with other plastics, with different proportions of additives, can be made of different specifications of products. Because PBT has good heat resistance, weather resistance, electrical properties, water absorption, good luster, widely used in electronic appliances, automotive parts, machinery, household goods, etc. , and PBT products and PPS, PC, Pom, PA and so on are collectively known as the five engineering plastics. 3 the shutdown time of PBT treatment is less than 30 minutes, and the shutdown time can be reduced to 200 ° C. When reproducing after long-term shutdown, the material in the cylinder should be emptied and new material should be added in order to carry out normal production. 4 the post-treatment of the products does not need to be carried out under normal circumstances, and if necessary, it needs to be treated at 120 ° C for 1 ~ 2 hours. Polybutylene terephthalate is a crystalline thermoplastic engineering
