热塑性弹性体生产现状与发展趋势 总被引:3,自引:0,他引:3
梁诚 《石油化工技术经济》2005,21(1):35-40
热塑性弹性体(TPE)是一类应用广泛兼具有橡胶和塑料特性的高分子材料。目前很多橡胶领域都可以采用热塑性弹性体替代,特别是我国汽车工业的高速发展,为各种热塑性弹性体的发展提供了巨大空间。文章重点介绍了热塑性弹性体特性及应用、生产现状、市场消费和发展趋势,对我国今后TPE的开发与产业化提出了以下几点建议:开发茂金属催化剂合成的新型TPE;加快动态硫化技术和纳米复合材料技术的产业化和推广应用;推进汽车工业需要的TPE国产化进程;加大TPE改性和与其他树脂的技术开发,提升TPE材料性能;研究新型TPE配方、加工助剂的使用、加工设备和加工工艺。 相似文献

热塑性弹性体(TPE)由于具有硫化橡胶的物理机械性能和热塑性树脂的工艺加工性能,又不需要经过硫化,因而作为第三代橡胶,近年的发展异乎寻常.在橡胶工业中的应用范围日趋扩大,除大量用于制鞋之外,现已涉及胶带、胶管、胶板、胶条、胶布、胶粘剂、密封剂等诸多方面,尤其在胶管及各种胶板方面已占相当比重,大量取代了橡胶.热塑性弹性体(TPE)的应用现已几乎涉及到合成橡胶的所有领域. 相似文献

聚烯烃类热塑性弹性体发展潜力大 总被引:3,自引:0,他引:3
聚烯烃类热塑性弹性体(TPO)由橡胶和聚烯烃构成.通常橡胶组份为三元乙丙橡胶(EPDM)、丁睛橡胶(NBR)和丁基橡胶;聚烯烃组份主要为聚丙烯(PP)和聚乙烯(PE),TPO目前成为汽车和家电领域的主要橡塑材料,其中汽车上用量占总产量的75%,以上,成为热塑性弹性体(TPE)中增长最快的品种,目前TPO产品中用量最大的是EPDM/PP。 相似文献

I review studies of the determinants of market performance in the aircraft, passenger airline, supermarket, liner shipping,
and hospital industries, and of mergers and market performance in markets for fast food, soft drinks, and retail gasoline.
Common factors are that more competitive market structures accompany better market performance, and that firm conduct and
industry-specific factors play independent roles. 相似文献

Performance of domestic market
The domestic consumer market has basically remained steady since the be- ginning of the year. Monthly, the growth of consumption has been steady and slowing down recently. The retail sales of consumer goods in October reached 2.4 trillion yuan, up 11.5% year on year, and 10.8% with price factors excluded. Totally, the consumption growth has re- mained steady. The total retail sales of consumer goods in January-October went up 12% year on year, the same as that of the first half year. While the growth of investment continued to fall, constlmp- tion has played the role of a stabilizer in economic growth. Following are the main characteristics of the consumer market in October. 相似文献

Allegations of price-fixing by US egg producers maintain that the industry’s strategic use of export programs softens competition
in the domestic market. This study provides an empirical investigation into these allegations using retail market data from
a specific California retail market. Our findings suggest that the antitrust complaints have economic merit, but the deviations
from competitive behavior are small. 相似文献
