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。tpu te70aa╅tpu te70aaevald720seriespcˉ7100-15 pa66美国杜邦70g35hsl bk267pbt hn7330pa9t/g2450pa66/re002ppa/uc008htpu 110-50pom vw-32abs ht-550 tpv 土耳其英菲力 vu420-55apps ofb32i pc/abspx10-x07pps ofl36xxc pa66 kdt1020eba/3427ac abs日本旭化成at900pcˉ175dfep 106 pbt广州lggp2306fwpmma sx-304b asainp894ppo gfn1-520vppˉcx04-81pp 65f5-4 pp韩国韩华道达尔fb51apbtˉ5010trxapa66/1213hstpu/5-40/08 pp印度信诚h200mapa66ˉ70g20hslevald713.93moldingpmma 902-70pp 5069pp/trc453nepmma/v046tpeˉ2102-85appe x333z
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 te70aa╅tpu te70aappˉtl1308 pa46日本dsm ts200f10 bkpmma4494pc exl9335/asa/pc/kr2864cpbt hsg-w-0270bpc/fl905pc/abs/cy1200ncpcˉ1302uv-08 pa6荷兰dsm k222-dabs hfa450pbt/bm6450xd/pa66 gyyilpp/rp374rpmma ird30pc/abscwr700mtpe fa7-1101eva1360pc 3025n2pmmadf22-zk6brpom f20-03pps ox10324 tpv 韩国乐天化学 hx-075anpp k4826tpu/2103-80aepc/abs tn-3713bpc/abs/tn-7500f/pc/amhi240ftpu 3685aupc/abs gn5001 k0163epa12/t5000pcˉ500poe/8480 pa12 美国杜邦 pa2072pa66/pa841pp st860k pc 基础-塑料 lux9616pom 500cl
