我国MPPO市场前景广阔

我国MPPO市场前景广阔 MPPO是PPO（聚苯醚）与苯乙烯聚合物形成的塑料合金。近两年来，MPPO的市场需求与发展速度有了较大幅度的增长，具有综合优良性能的MPPO材料在汽车、建筑材料、抗静电包装材料等方面广泛使用。 在世界MPPO的消费结构中，电子电气及家用电器、办公设备与运输机械约占80以上。美国在运输机械方面消费量最大，约占其消费量的30左右；欧洲在汽车等运输机械及电气工程中所占比例分别为30及50；日本是办公自动化设备及电子电气与家用电器最发达的国家，2000年所占比例分别达到44及35，而在汽车方面只占12。 目前，我国MPPO的消费主要集中在电子电气与家用电器领域，约为65，在办公自动化设备领域为15左右，在汽车工业领域不到6。今后，随着MPPO应用技术的发展、社会环保意识的增强，其市场发展前景将更加广阔。 电子电气及家电领域 传统电器、电子部件用的骨架材料等将继续使用各种型号的MPPO材料。MPPO具有较大增长及竞争优势的应用领域主要表现为以下几个方面： 电脑磁盘与光盘驱动装置及其小型壳体材料将继续使用MPPO，其需求量处于旺盛的上升势头；笔记本型商用微型机、手机等电子信息终端产品对MPPO的需求十分旺盛；电源适配器、充电器及二次锂离子电池外装盒等使用大量的MPPO新材料；TV、CRT及数码相机等消费的增长为MPPO材料带来了持续消费的活力。MPPO在电子电气及家用电器应用领域的另一具有巨大发展潜力的市场是高频印制电路板基板材料，由于热固性PPO合金材料具有优异的介电特性、较低的成本、良好的成型性与耐溶剂性能，预计在该领域将占有很大的市场份额。 办公自动化设备领域 MPPO优异的物理性能、机械性能、阻燃性、低比重、尺寸稳定性与高精度的特点，将在打印机、复印机、传真机、商用电脑等大型壳体材料中大量使用。但由于价格低廉、耐光性更加优良的阻燃PCABS合金的使用，MPPO材料遇到PCABS合金的挑战。然而，在耐光性要求相对较低的背面壳体材料上，MPPO低比重的特点仍将保持其应用的竞争优势。此外，新一代具有隔音阻尼特性的MPPO新材料的开发，对于开发高档静育型办公自动化设备将具有较大的吸引力。 汽车工业应用领域 随着“十五”期间我国汽车工业的发展，MPPO的需求量将显著增长。目前，以PPO/PS合金作为汽车仪表板材料已得到欧美及日本等国汽车制造商的定型使用，尽管受到低成本及汽车环保概念、PP改性材料的影响，但具有良好隔音性能的新一代MPPO材料的出现，以及MPPO优良的耐热循环使用的特性，将逐步坚定MPPO在该产品上的使用份额。 PPOPA等合金除在汽车散热器、车轮罩盖、保险杠、车门及立柱护舷板、中央门锁等部件上仍保持竞争优势外，在汽车外板材料及前灯反射体等方面将有强劲的增长势头。在电动汽车用充电电池等方面将具有较大的应用潜力。 以北京市化工研究院近二年开发的高耐热前灯反射体材料为例：与传统的铸铝、SMC材料相比，其成型周期缩短了7590，质量减轻了1/31/2，而且真空镀铝光洁度高，反光性大大改善，总成本降低了30以上。 其它市场需求方面 MPPO在工程塑料中独树一帜的耐热、耐水性能，将在给排水系统、水表水泵、化工用管道、阀门以及市政工程等领域继续保持增长的势头；MPPO具有良好的阻燃性，又适合于环保发展方向，在阻燃类工程塑料产品（如无卤合金电子材料与电缆材料等）中具有极强的竞争优势；MPPO的比重小、成型性好，成型收缩率低而且恒定，可使制品尺寸精密，很少发生脱模问题，因此常用于精密产品的制造，如摄像机、照相机、手机、软磁盘驱动装置、钟表、测量仪器、轴承等滑动部件及航空仪表、医用外科手术器械、军工产品等。 我国是MPPO最有发展潜力的市场之一。据估计，随着电子电气与家用电器领域的进一步发展及“十五”期间汽车工业产量与档次的提高，MPPO的使用量将以每年20以上的速度增长，产品的消费结构将发生较大的变化，其中在汽车工业中所占比重将有较大幅度的提高。 中国化工报2003.1.19
