c, nozzle overflow - adjust the position of the die.
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。ldpe 830ldpe 830pom/zld75/eva/30e753tpu c9---pa66 htnfr52g30ltpu 786ltpu alre9---pmmagppp 528k pcˉ1-9371pc/abs/f-101pmma bm-606 pa6美国杜邦73g15hsl bk363pa6ˉfv-30pa6/b50l01 poe美国陶氏8480tpu 109---epc/abs/t65hg/tpu s180a lcp日本住友化学c130 vf2001pbt 2100-104btpv 3450npa66 a3hg7ppeps30rapa6 kn170sapa66 fg170x51asa 815tpu 58092pp/ml004pa6v40pmmaird-30evaad2528eh2pcˉvr2200 pc 日本出光 g-3030 eva中石化燕山155epc mx1004pbt 1700pc zll19cu pa66德国弗瑞圣塔a63 vo
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.ldpe 830ldpe 830pc dl-4520pc 3025m10lcpˉl204g35epom 111dp pp北欧化工be677aipbt xfr4840tpu 107--- pom 日本旭化成 cf452 abs sx-200pbt 1410g6 gbk2pa66/rl004tpe/dgr6440ncpmma clg902pa66 tech2530v0 p60tpe tx-5164upa6/gp2500a eva美国杜邦880 ldpe中石化燕山ld450pomm90lfppˉp602f pom 美国杜邦 1700ppa66 80g33l evaul8705seriespc/223rcpp pd4108pa12/e40-s3ppˉm-1000hspomaw-09tpeˉmj8301ctpe a3080a /tpe/bt-1028deva/ul40028ccuhmwpe xm220pp fs3029pc hp4tpu i-9---024aw tpee美国泰科纳mt9647pbtˉb4300g6ltbk
