POM☆原料可在-40℃~100℃温度范围内长期使用。POM☆极易分解,分解温度为280℃,分解时有性和腐蚀性气体发生。故模具钢材宜选用耐腐蚀性的材料制作。力学性能POM☆强度、刚度高,弹性好,减磨耐磨性好。
POM material can be used for a long time in the range of -40 to 100 C. POM is easy to decompose, decomposition temperature is 280 degrees, and there are excitant and corrosive gases in decomposition. Therefore, steel should be made of corrosion-resistant material. The mechanical properties are POM, high strength, high rigidity, good elasticity, good abrasion resistance.PP 330-NA00 ╗ PP DM55 PP/CB1143G PA66三菱工程3021G-30 POM 美国赫斯特 C9021TFPP/EP546TPC ML7694PBTˉTV6240PP MFL36S LCP宝理E130iPPE/AH80PA6ˉLS240POMWR90ZPA6ˉ8232GHSPPE 340VPPˉ500.00 EVA美国杜邦20D875PC DS0026PA66/SF50-02AF3001PC/PZ725EVA/UE672006PA6ˉAN0511SNˉ PA612美国杜邦FE3734PC/LUX2614GPC/ABS/T95MF/ PC 三菱工程 GS2010MPH PA66上海罗地亚A216BLEVA/LV362PBTˉ43OM 3010PA10T/HTXE4027/PA12/1050ZB92ABS NTVA6 BL2280 PC 台化出光 IR2500PA66/105FA66132FPOM/KP004AXP/PA66/C1G30 EVA宇部V215EVAMP34
PBT聚对苯二甲酸***酯,又名聚对苯二甲酸四次酯。英文名;Polybutyleneterephthalate。简称PBT PBTP或PTMT,它是对苯甲酸与1,4-***的缩聚物。可由酯交换法或直接脂化法经缩聚而制得,今后的发展趋势为直接酯化法生产。PBT和PET一起被称为热塑性聚酯。
PBT poly (butylene terephthalate), also known as terephthalic acid, four methyl ester. English name; Polybutyleneterephthalate. Referred to as PBT PBTP or PTMT, it is a polycondensation of benzoic acid and 1,4- butanediol. It can be prepared by transesterification or direct esterification by condensation. The development trend in the future is direct esterification. PBT and PET are called thermoplastic polyester together.
