合成树脂

合成树脂为人工合成的高分子聚合物,是由低分子原料(如乙烯、丙烯、氯乙烯等)通过聚合反应生产的。工业上常用的聚合方法有本体聚合、悬浮聚合、乳液聚合和溶液聚合四种。通常为加热可软化的固体,受热时通常有熔融或软化的温度范围,在外力作用下可呈塑性流动状态。

中国石化拥有世界先进的生产工艺,近年来自主知识产权和技术应用比例有较大提高,部分技术达到国际先进水平,可生产聚乙烯、聚丙烯、聚氯乙烯、聚苯乙烯、ABS等五大合成树脂和聚醚、环氧树脂等产品,并成功开发生产了多种高附加值的专用树脂,目前国内市场使用的聚烯烃产品中90%以上都能够生产。

2008年,中国石化五大合成树脂产量占全国总产量的38%,位居中国和亚洲第一。五大合成树脂中的聚烯烃国内市场占有率约为41%,产能居世界第四位,其中,聚丙烯产能居世界第二位,聚乙烯产能居世界第四位。

Synthetic resin is a high-molecular polymer produced artificially through the polymerization of low-molecular monomers such as ethylene, propylene and chloroethylene etc. The most common industrial polymerization techniques are bulk polymerization, suspension polymerization, emulsion polymerization and solution polymerization. Synthetic resin is typically a solid which would soften when heated. There is typically a temperature range within which synthetic resin would melt or soften when heated. In the presence of an external force, synthetic c resin may exhibit a plastic flowed.

Sinopec has advanced synthetic resin production technologies. In recent years, the company’s proprietary technologies have been playing an increasingly big role in the company’s petrochemical production. Some of these technologies are among the most advanced worldwide. The products mainly include polyethylene, polypropylene, polyvinylchloride, polystyrene, ABS (known as the five major synthetic resin products), polyether, epoxy resin ,etc. The company has developed a series of high-value-added specialty resin products. Sinopec is capable of producing over 90% of the polyolefin products available in China's domestic market.

In 2008, 38% of China’s output of the five major synthetic resin products are produced by Sinopec, making the Company the largest producer of these products in China and Asia. Sinopec controls around 41% share of China’s domestic polyolefin market and its polyolefin capacity is the fourth largest worldwide. The company’s polypropylene capacity is the second-largest worldwide and polyethylene capacity is the fourth-largest worldwide.

SCS’ synthetic resin products include low-density polyethylene (LDPE), high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) and acrylonitrile-butadiene-styrene (ABS),etc.

Major Sinopec manufaturers that produce synthetic resin include Sinopec Beijing Yanshan Company, Sinopec Qilu Company, Sinopec Shanghai Petrochemical Co., Ltd., Sinopec Yangzi Petrochemical Co., Ltd., Sinopec Maoming Company, Sinopec Guangzhou Company, Sinopec Tianjin Company, Sinopec Zhongyuan Petrochemical Company, Sinopec Qingdao Refining and Chemical Company, Sinopec Zhenhai Refining and Chemical Company, Sinopec Baling Company, Sinopec Wuhan Company, Sinopec Gaoqing Company, Sinopec Jinan Company, Sinopec Jinmen Company, Sinopec Luoyang Company, Sinopec Jiujiang Company, Sinopec Changling Company, Sinopec Hainan Refining and Chemical Company, Sinopec Cangzhou Refining and Chemical Company, Sinopec Secco Petrochemical Company, Sinopec Yangzi-BASF Company, Fujian Refining and Petrochemical Company Limited and Shanghai Golden Phillips Petrochemical Co.,Ltd..
