聚丙烯PPH 12020是一种澄清的高流动性均聚物,其熔体流动指数为60 g/10 min。聚丙烯PPH 12020的设计具有很高的刚度和出色的透明度。适用于透明包装的注塑成型。 Unreinforced grades have abundant strength and flexibility, and have strong characteristics against brittleness. UL-certified slow-burning(94HB) and self-extinguishing grades(94V-0,V-2) exist, and electrical properties exhibited are the highest of any thermoplastic. Low water absorption is exhibited, and excellent electrical properties(CTI and GWIT) are retained over extended periods of usages, even with widely varied temperature and humidity conditions. The surface of molded products is smooth, and a low coefficient of friction is exhibited.As the amount of froction is low, PBT is suitable for use in application requiring friction and wear properties. The material is exceptionally reliable, with small in-use dimensional variation, and superior molding stability and dimensional precision. Long-term chemical resistance is exceptional, and at room temperature, there is almost no degradation in properties after. Both unreinforced and reinforced grades exhibit exceptional flowability, and excellent processability. Application:VCD drive frames Connectors Trimmers Switch buttons for gas-fired instantaneous water heaters Relay blocks Driers Rectifiers Outer handles Height sensor cases Door mirror stays Drive component housings Energy saving lamp. |

石油化工行业:成品油价钱暂缓下调 关注石化行业变革推…
2015-12-18 发改委暂缓调整国内成品油价格。12月15日,国家发改委发布新闻《国内成品油价格形成机制将进一步完善》,根据现行成品油价格形成机制的有关规定,暂缓调整国内成品油价格。 国际油价处于低位,国内成品油价格暂缓调整。受国际原油价格下跌的影响,自11月份以来国内汽、柴油价格已经连续三次下调,经12月1日下调后,汽、柴油标准品最高供应价格每吨分别为6105元和5155元。目前国际油价低于40美元/桶,本次成品油下调暂缓执行。 炼油公司受益。根据卓创资讯报道,按照国际油价 |
