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。tpe g3000***tpe g3000pc df0029r pa612美国杜邦fe5382 pa66美国杜邦70g13hs1-ltpeeˉ5450(a)ˉppˉhf5157pp 2175hu pp 3317pnc1poml0-21tpeˉcm600-vppˉ3052uxˉpc/df0029ereva/fl00328pa6/k224-pg8tpuˉalrg500ppˉ1102jˉpps/r40hfpa66 ld610ppˉba390tfppˉh7914pbt b0620fn18tpe td6psntpe g7970-1001-00ppˉcp53-30pa66/r1000spa12 lv-3xesdeva/n1014pa66 ra353m8pa66/m-1016mpr/2265utpa6t tkr4350pp/cnr012eva/3014tpe 5526ppˉh533-35rgupom s2320-003proppˉh7700tpv 101-60w261pc pc-1150ul
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.tpe g3000***tpe g3000pc 121r-111pa6ˉkn153g30tpv w700b tpu ub601pp r3420 tpu美国ron r495pbt/wfl33pc/pc-1700g10fr/台湾奇美pc/8330-10pcˉg-3420 lldpe北欧化工fb2230pc/abs gp-5008bf lcp美国泰科纳5145l bk010pa6 bg-35rpbt/cn7030nn/bb/pa6ˉpx99848 pc 台化出光 ir2200 wwtpuˉmvt75at3pc/abs fr3010pp sfr-171h pp k9017pp/hmu216 pc 上海科思创拜耳 9425tpv/121-80b2306epdm 4045pa66/rf203xxheva 5269pa66 htnfr52g30bl pom 日本旭化成 4010ppˉqr674kpa6 gf45tpuˉa85e4607epc/1201-15 eaa美国杜邦53070pbtˉ4631tpee g4774eva/1181tpe hx8icn
