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。pc 110v╱╲pc 110vpbt/420cpa66/rv008epa6ˉ6mkf3010hi tpu美国路博润58252pp/ep302kpp 1088pp h5231pbt/b2550fc/pp bc03b pc/abs 上海科思创拜耳 t90 xg pom 马来西亚宝理 wr-01pa66ˉgp2339b pa6t 日本三井化学 c240kpom 527uvgypc gsn-2020r2 pa6/bkv30ef lcp马来西亚宝理e130ipeek 美国壳牌 d26hm100-ncpp 7143kne1pom k300pps//fgf10pbt sv-1120mpom n2320u017ppˉ8001eva/7920mpc 244r-111pp/pg6n1pbt kp270expa66/ral229pa66/218v40pc 1301v-10 hdpe沙特埃克森美孚hta-001hdpp/1697ppˉ3200hˉpmmavpa6/gp2300apbt sk645fr pmma 上海赢创德固赛 8n
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.pc 110v╱╲pc 110vpps pn9008lg pbt dr48pc/urc2500ppo 220zppˉr020eva/v115eva33-45pp/tsopem1g73024poe/6251ym4pponlv025-111pp hj541cptpu 445 pbt新光d202g30 df4806tpu wht－1285pbt wf0031whpa6 b100qppp gf50-10 pp 612mk10pa6ˉv35htspa6ˉpk005ei2 pa66美国杜邦fr70m30 vo gy450 pp沙特appc 1102k tpv 美国埃克森美孚 8201-60ppˉmb006semaa/tc114lpa6ˉex-1222 pa66深圳东丽cm3001g33 b3 eva美国埃克森美孚ad 2528pa6/k224-g6tpvˉ241-80w236ˉ pps日本东丽a400m d1tpu/1154dpp ep200ktpu/c60ahpm pp马来大腾石化epc 40rpc exl1433ttpe dgx7354asatw20
