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。tpu 90aht∩tpu 90ahtpom c27021-gv3/30pbt wfl33pa6 r60espp r701tpe v-870 pc 德国科思创拜耳 2400pbt 1200mfppo/px1543pc s1000u pbt基础---塑料325 bk1066pc 920asrpp 1264e1pbt e206g30pcˉ24urpc/abs/gp5001af/pa66 79g13hslppˉ3261pom460pmma/2000tpu ete60dspmmazk4hrpc/abs 上海科思创拜耳 t-45ppˉ523ptpe/dgx6280clpa66ˉrx06424pps pn9008lg pbt/cn7015nn/bb/pc/de004erpmma/sr6200ppe/sa9000pa66/21zlvppˉp20b03eva ev-600pps hbema法国阿科玛18ma02pp/nj201aieva 3165pom/fb2030/
pom material can be used for a long time in the range of -40 to 100 c. pom is easy to deco-e, deco-ition temperature is 280 degrees,&there are excitant&corrosive gases in deco-ition. therefore, die steel should be made of corrosion-resistant material. the mechanical properties are pom, high strength, high rigidity, good elasticity, good abrasion resistance.
pbt聚对---丁二醇酯，又名聚对---四次酯。英文名；polybutyleneterephthalate。简称pbt pbtp或ptmt，它是对---与1,4-丁二醇的缩聚物。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/ptmt, it is a polycondensation of benzoic acid&1,4- butanediol. it can be prepared by transesterification/direct esterification by condensation. the development trend in the future is direct esterification. pbt&pet are called thermoplastic polyester together.tpu 90aht∩tpu 90ahtpa12/a4000 ldpe中石化燕山ld100-acpc/absnx11302tpe ata4aonpa66 70g13hsl1 eva美国杜邦4260pc/absgn5151rfapc g-3110hpc h-3000pps f181px1-x1pa6ˉs60g1v30ppˉ1043npbt tv4261kl lcp美国泰科纳e130i vf3001 pc 基础---塑料(南沙) fxd121reva /214apomkx02764pa66ˉrc00a pa66日本东丽hf3074g30pa66 kn333hi5bl tpv 美国埃克森美孚 8281-90medpp 3040ppˉmx06402hˉppˉs1004pp fh51 pa66德国巴斯夫a3wg5pc/abs/hp-1000h/pc/abss66spc ld7890 pc 日本出光 ry1900 bkpcˉ3025utpe tp8vczpa66 dpakv30href pc 日本住友化学 301-06pc/301-15 pc/abs 美国盛禧奥斯泰隆 7570 bkpa66 n21a 4n-c tpv 美国埃克森美孚 253-50
