尼龙12短缺影响全球汽车生产

2012年3月31日,嬴创工业集团在德国马尔（Marl）的环十二碳三烯（CDT）装置发生致命的爆炸和火灾,致使由其衍生生产的尼龙12树脂发生短缺,尼龙12树脂是涂料以及汽车行业制动系统和燃料处理连接器应用领域制造必不可少的材料。     

旨在消除尼龙12全球性短缺的一系列举措

材料供应商和汽车制造商经过商讨,共同面对尼龙12的全球性短缺问题。尼龙12主要用于燃料管和制动管的连接器和其他如油管和软管等汽车零配件。预计在2012年下半年里尼龙12短缺问题将持续存在。法国Arkema集团、瑞士EmsGrivory公司、Evonik工业集团和宇部兴产是尼龙12的主要供应商。Evonik工业集团是唯一一家在尼龙12树脂中纳入关键原料环十二烷三烯(CDT)的供应商。3月31日     

赢创扩大德国工厂尼龙12树脂产能

正赢创工业集团位于德国马尔的工厂增加了1100万磅(5000吨)的聚酰胺(尼龙)12树脂年产能。该厂在2012年初遭遇重大爆炸和火灾事故而停产。尽管早已恢复生产,但产能供不应求。总部位于德国埃森的赢创集团生产Vestamid品牌的聚酰胺12树脂。赢创公司官员在6月27日发布新闻稿说,此次扩能延续了该公司多年来不断响应市场需求的策略。高性能聚合物负责人Michael Pack在新闻稿中说,Vesatmid材料非常抢手。"在该厂临时停产时大热的那些替代材     

Influence of temperature on Newtonian viscosity of Nylon-12

Summary The intrinsic and zero snear viscosity of Nylon-12 is investigated in a mixture of carbon tetrachloride and phenol (1:1 by weight) and in metacresol at 298–348K temperature range. The variation in viscosity with temperature is explained in terms of entanglement among the polymer molecules and the thermodynamic quality of the solvents. The results so obtained are scaled using a reducing parameter proposed by Baloch. It is found that this parameter works very well over the entire range of concentration and temperature investigated, even in mixed solvents.     

Polymer Blends of Nylon-12 and Abs: Synthesis and Characterization

Six different ratios of blends from nylon-12 and acrylonitrile-butadi-ene-styrene (ABS) were prepared by the melt mixing technique. Thermal analysis of these blends were carried out by differential scanning calorimetry and thermogravimetric analysis. It has been observed that the blend ratios such as 70/30 and 60/40 of nylon-12/ABS were more compatible in comparison with other blend ratios. It is evident from the values of glass transition temperature and activation energy. Thermogravimetric analysis shows a decreasing trend of pyrolysis temperature of these blends with the increase in ABS concentration. The melt-flow index and density data are found to indicate better physical and flow characteristics in the blend compared to pure nylon-12.
