582.高分子材料的阻燃抗静电改性研究进展
[化学原料和化学制品制造业,橡胶和塑料制品业] [2014-09-17]
近年来,抗静电高分子材料在现代科学研究中显得异常活跃,2000年的第一个诺贝尔化学奖即授予了在此领域曾做出卓越贡献的3位科学家,以表彰他们在研究导电高分子材料领域的杰出成就,再次显示了社会对该研究领域的关注与重视。 一般的高分子材料都是通过稳定的共价键结合,它们自身不能电离,而且主链结构上很少或没有极性基团[例如聚乙烯(PE),聚丙烯(PP)],因此分子链间存在很大的禁带能。级而使载流子无法自由运动,它们具有非常高的表面电阻和体积电阻[例如PE表面电阻率达1016Ω以上,PP达到1018Ω以上,(丙烯腈.丁二烯,苯乙烯)塑料(ABS)达到。1016Ω以上],是良好的绝缘体。摩擦时塑料会产生静电荷积累,导致吸尘、电子器件击穿,引起集成电路破坏、放电和燃烧等事故,给工业生产和日常生活带来很多麻烦以及经济损失。同时高分子材料具有易燃性,遇火后会发生剧烈燃烧,且燃烧速度较快,同时伴随有大量有毒气体,对社会危害极大。因此,只有不断开发和使用高性能的阻燃抗静电高分子材料,才能够克服静电积累和易燃性对人类社会生活所带来的危害。

585.行业月度报告-化工201407
[橡胶和塑料制品业,化学原料和化学制品制造业] [2014-09-15]
7月,在微刺激政策下,宏观经济出现回升迹象,化工行业工业增加值增速改善。 1~7月,化工行业增加值同比增长11.0%,增速同比提高0.1个百分点。从主要产品产量看,化肥、合成树脂、化纤产量增速有所回落,橡胶产量增速出现反弹。化工各子行业出厂价格指数继续以升为主,但仍低于100点,化工产品价格继续低于上年同期水平。7月份,随着工业需求回暖,国内化工市场逐步上行,相比去年同期市场活跃性及产品成交价格均大有起色。但是同时,多数化工产品仍面临产能过剩、库存高企等问题,化工产品价格依然处于历史低位。

590.全球BOPP薄膜市场报告(2014-2018年)
[化学纤维制造业,橡胶和塑料制品业] [2014-08-28]
BOPP is a polypropylene film widely used in packaging. Biaxial orientation is a process that involves heating the cast film continuously to bring it to a stretchable temperature, after which the film is stretched in a machine and subsequently drawn in the transverse direction. This process is carried out by tenter and bubble methods. BOPP films are UV resistant and have a smooth surface, good clarity, and excellent chemical and abrasion resistance properties.
