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.╮ PA6 F130-C2 →POM 德国巴斯夫 W2320-00A6ˉK224-G4UTPU/2355-95AEPC/ABS GN-5001TFPA66 A3WG8EVA2106 EPDM SK S537-2PP M800ETPU美国泰科纳CF40-01 NAPPˉMFX-1008HSPP/FRF3014/PC HP1HFPP 7533 TPE CA3-7001PA66 A3W2G6PP/MC004PC/RZ300G2PMMA VS POM 基础创新塑料 KL-4030PP 840N PFA 美国杜邦 TE9724PC/ABSGN5008LFPPˉ350LLG-202PA66 AKV30GHRDUS023TPU A85P4380EVA/1641PPˉHK060AEBORFLOWPPˉ70BS PC 乐天化学 PC -1070PBTˉGP-5000PA6ˉC536XT LDPE卡塔尔石化FD0270PP/R12232PA66/A2LG6301PP B-M30-VTPUˉC95A10 PC 德国科思创（拜耳） 2458PA66ˉSF6-02
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.
