我国是世界第二大溶聚丁苯橡胶生产国,2011年产能为26万吨/年,有4套生产装置,但仅有2套装置的产品投放市场,且由于产品质量不高、牌号较少,市场占有率很低。德国朗盛公司预测,未来几年世界SSBR的年均需求量将以超过10%的速度增长,预计到2015年,全世界SSBR的总需求量将超过180万吨。若所有新扩建装置能够按计划完成,2015年装置开工率则要达到90%才能够满足市场需求,市场供应紧张,SSBR开发利用前景广阔。由于我国高性能轮胎需求较少对SSBR需求量不大,SSBR的综合性能不及ESBR且成本较高,笔者建议我国SSBR产能扩张应慎重,现阶段更应着重于培育和开发市场。
China is the second largest producer of soluble poly (styrene butadiene rubber) in the world with a production capacity of 260,000 tons / year in 2011 and 4 production facilities, but only 2 sets of products are put on the market. Due to the low quality of the products, Less, the market share is very low. The German company LANXESS predicts that the average annual global SSBR demand will grow by more than 10% in the next few years. It is estimated that by 2015, the total global SSBR demand will exceed 1.8 million tons. If all new expansion units can be completed as planned, the operating rate of units will reach 90% in 2015 to meet the market demand. As the market is in short supply, the development and utilization of SSBRs are promising. Due to the low demand for high performance tires in China, the demand for SSBRs is small, the comprehensive performance of SSBRs is not as good as that of ESBRs and the cost is relatively high. The author suggests that the expansion of SSBR capacity in China should be cautious. At this stage, more emphasis should be placed on nurturing and developing markets.
