中国台湾台塑PP 1080

PP的市场前景:
PP有着广阔的应用前景。随着高分子材料加工设备的不断进步和增容技术手段的提高，越来越多的共混体系可以采用动态硫化技术进行加工，这必将会导致一系列性能优良、成型加工方便、设计灵活的热塑性硫化胶出现，传统的硫化橡胶应用领域将越来越多地被热塑性硫化胶所取代，PP在工业领域和生活消费领域的应用必将得到更为迅猛的发展.PP在我国的销量已一个月大约70万吨左右，目前中国是世界上用量的消费国，随着生活的多姿多彩PP产品越来越多，让消费者感受到科学的优越性。
At present, the business scope of Formosa Plastics Group is very wide, including oil refining, petrochemical raw materials, plastic processing, fiber, textile, electronic materials, semiconductor, automobile, power generation, machinery, transportation, biotechnology, education and medical undertakings.

台塑集团产品介绍：在塑胶原料制品方面，包括PVC粉、VCM、液碱、盐酸、塑胶改质剂、高密度聚乙烯、聚乙烯醋酸乙烯酯/低密度聚乙烯、线性低密度聚乙烯等产品，其中PVC粉年产能一佰三十万一仟公吨，不仅系中国台湾生产厂，若含美国及大陆投资公司年产能达二佰九十二万公吨，是世界上PVC粉生产厂。配合环保政策，碱厂生产方式由法改采离子交换膜法，液碱年产能一佰六十万公吨。塑胶改质剂是本公司自行研发成功之产品，其中MBS耐冲击改质剂年产能一万九仟七佰公吨、PA加工助剂年产能二万五仟公吨、合计年产能四万四仟七佰公吨，对国内发展高附加产品颇有助益。高密度聚乙烯年产能五十三万公吨，系国内生产厂，聚乙烯醋酸乙烯酯/低密度聚乙烯年产能二十四万公吨，线性低密度聚乙烯年产能二十六万四仟公吨，聚丙烯年产能四十万公吨。

PP process introduction:PP melting temperature: 225-285c, do not exceed 280C. PP mold temperature: 42-82c, 52C is recommended. The degree of crystallization is mainly determined by the mold temperature.
Injection pressure: up to 1850 bar.
PP injection speed: the use of high-speed injection molding can reduce the internal pressure to the minimum. If there are defects on the surface of the product, low-speed injection molding at higher temperature should be used.
PP runner and gate: for cold runner, the typical runner diameter range is 5-8mm. It is recommended to use the injection port and runner with round body. All types of gates are available. Typical gate diameters range from 1-1.5mm, but Gates as small as 0.8mm can also be used. For edge gates, the minimum gate depth should be half the wall thickness; the minimum gate width should be at least twice the wall thickness.

由于中国台湾下游加工业大量外移大陆，加上大陆经过十多年的经济后，其石化工业已快速发展，而且所需原料仍须大量仰赖进口，在大陆加入WTO后更将创造庞大商机，惟受大陆高关税保护措施影响，中国台湾原料要打入大陆内销市场相当困难。为争取大陆内销市场，台塑集团已积极进行大陆布局，并于大陆宁波经济技术开发区规划一石化专区，目前获准投资项目包括年产能30万公吨PVC厂已于94年1月完工生产、年产能23万公吨丙烯酸酯厂已于95年3月完工生产、年产能45万公吨聚丙烯厂已于97年4月完工生产，及年产3万公吨高吸水性树脂厂已于97年3月完工生产。
