pvc was found two times in nineteenth century, one was henri victor regnault in 1835,&the other was found in 1872 by eugen baumann. in the two opportunity, the polymer appeared in a beaker of vinyl chloride placed under the light of the sun&became a white solid. in the early twentieth century, russian chemist ivan ostromislensky&chemist fritz klatte of griesheim-elektron company tried to use pvc for commerl purposes, but the difficulty was how to process this hard, sometimes brittle polymer.、flow: 23 c 1.2 to 1.5% astm d955、the molecular structure of conventional lldpe is characterized by its linear main chain, with only a small amount/no long branched chain, but contains some short branched chains. without long branching chains, the crystallinity of the polymer is higher.、pc/abs典型应用范围:汽车内外饰:仪表板,饰柱,仪表前盖,格栅,内外饰件2.商务设备机壳和内置部件:/台式电脑,复印机,打印机,绘图仪,显示器3.电信,电话外壳,附件以及智能卡sim卡:4.电器产品,电子产品外壳,电表罩和壳体,家用开关,插头和插座,电缆电线管道5.家用电器,如洗衣机,吹风机,微波炉内外部件等。、pvc改性pvc树脂是一个极性非结晶性高聚物,密度:1.38g/cm3,玻璃转变温度:87℃,因此热性差,不易加工。不能直接使用,必须经过改性混配,添加相关助剂和填充物才可以使用。而因添加的相关助剂和填充物的种类和分数的不同,这就决定了所制备的pvc材料性能和要求是不一样的。我们通常称之为pvc配方,严格说来是pvc改性配方,而pvc只有经过改性才能使用。、(9) if the finished product has been produced many times, in order not to be scrapped due to too high internal stress, annealing treatment can be carried out, which can relieve the tension of the outer surface&relieve the internal stress.、petg的主要用途:(1)板、片材使用常规的成型,可以制备1~25.4mm厚的材料,具有的韧性和高抗冲击强度,其抗冲击强度是改酯类的3~10倍,成型异,冷弯曲不泛白,无裂纹,易于印刷和修饰,广泛应用于室内外标牌、储物架、自动售货机面板、家具、建筑及机械挡板等。pctg卡主要应用于欧洲,但在北美、亚洲也了越来越多的应用。原因是具有很宽的加工范围,高的机械强度和优异的柔性,比起pvc度高,光泽,容易印刷并且具有优势。petg材料应用于。visa的公司之一,1998年其全球卡片发行量为5.8亿张。该公司已二醇类改性聚酯(petg)为其材料。对于要求卡片材料对更友的guojia,petg可替代聚材料。visa还-:来自3个不同试验厂的结果显示,pe(150/iec7810)的所有要求,因此petg卡片在这里可能广泛使用。petg pn100、petg pn200、petg s2008、petg s2008l3、petg t110、petg t95、petg wp-65、petg wp-70、ema in recent years, the household electrical appliance industry in china has developed rapidly, with many varieties&large output. in 2003, there were 18 million 500 thousand refrigerators in our country, 42 million air conditioners, 17 million washing machines&35 million microwe ovens. according to the research consultation report of chinas urban family theater market in 2004~2006, it is estimated that the market scale of chinas home theater system will reach 6 million 900 thousand in the next 3 years. in addition, a variety of small household appliances also he a huge potential market, which is an excellent business opportunity for the modified pp. some manufacturers of plastic raw materials in china he developed spel materials for washing machines, such as pp 1947 series, k7726 series&so on,&he been welcomed by the manufacturers of washing machines. therefore, in the next few years, we should strengthen the development of pp spel materials for household appliances in order to meet the demand of market change. plastic pipe、(1) the first generation ppo alloy was prepared by blending ppo with ps in a wide range of co-ition&blending with polymers with styrene units to prepare ppo/ps type alloys. 、industrial policy barriers、abs电学性能:abs的电绝缘性,并且几乎不受温度、湿度和的影响,可在大多数下使用。性能:abs不受水、无机盐、碱醇类和烃类溶剂及多种酸的影响,但可溶于类、醛类及,受冰、植物油等侵蚀会产生应力开裂。性能是通过自动化的工具模拟多种正常、峰值以及异常负载条件来对的各项性能指标进行。性能特点是可加工性,良,流动性高、[use] a thermoplastic resin. it is used to make oil pipe, film, cable sheath&so on.、pvc (聚塑胶原料为微半状,有光泽。度胜于聚、聚,差于聚,随助剂用量不同,分为软、硬聚,软制品柔而韧,手感粘,硬制品的硬度高于低密度聚,而低于聚,在屈折处会出现白化现象。;不易被酸、碱腐蚀;对热比较耐受。聚具有阻燃阻燃值为40以上、耐化性高耐浓、浓度为90%的酸、浓度为60%的和浓度20%的、机械强度及电绝缘性良的优点。聚对光、热的性较差。软化点为80℃,于130℃开始分解。在不加热剂的情况下,聚100℃时即开始分解,130℃以解更快。受热分体是有体使其变色,由白色***浅***红色***褐色***黑色。阳光中的紫外线和氧会使聚发生光氧化分解,因而使聚的柔性下降发脆。这就是一些pvc塑料时间久了就会变黄、变脆的原因。、introduce
、pc/abs较之pc了流动性,了加工性能,了制品对应力的性,因而广泛应用于汽车内饰,外饰,车灯等度,高耐热零件。随着人们意识的,汽车行业elv等可回收法规的相继,原材料厂商也不断提供新的解决方案。作为工程塑料行业的者适时的推出了新一代pc/abs合金系列材料,它主要包括了耐水解性的pc/abs,用于免喷涂内饰的光泽pc/abs,耐化学品优异不易被油漆等侵蚀的耐化学溶剂pc/abs等系列产品。、mdpe molecular structure、thousands of thai plastic professional sales. makrolon 2403 pc bayer materialscience llc (gen kos)、70g33l、makrolon2467pcbayermaterialscienceag、modified pom
