浅析我国SBS产业链

Analysis on China's SBS Industry Chain

介绍了我国苯乙烯-丁二烯嵌段共聚物(SBS)产品的性能特点和主要应用领域,对当前国内SBS的供应和消费情况进行了分析,数据表明,近几年国内SBS装置开工率整体偏低,产能已经严重过剩。研究了近年来国内SBS下游领域的发展变化,随着下游行业的发展,国内SBS用于制鞋行业的份额将逐步萎缩,而在沥青改性、黏合剂、防水卷材、聚合物改性等领域的用量将稳中有升。结合国内SBS产品的现状,希望加大科研攻关力度,多生产环保类和特殊性能的SBS产品,提升国内SBS产品档次。

This paper introduces performance characteristics and main application fields of styrene-butadienestyrene block copolymer (SBS) products, and analyzes the current supply and consumption situation of domestic SBS. The data show that, domestic SBS average operating rate is at a rather low level in recent years due to massive overcapacity. Meanwhile, it reviews the evolution in domestic SBS downstream fields, and holds that, with the changes in downstream sectors, domestic SBS used in the footwear sector will gradually shrink, but will rise steadily in asphalt modification, adhesive, waterproof roll and polymer modification. Based on the status of domestic SBS, it hopes to strengthen research efforts, and produce more environmentally-friendly SBS products and specialty SBS products to upgrade domestic SBS industry.
