我国SBS的供需现状及发展前景分析

随着多套新建或者扩建装置的建成投产，我国苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）的生产能力稳步增长。2023年，我国SBS的生产能力达到161.5万t，表观消费量为91.5万t，预计2028年生产能力和消费量将分别达到200万和100万t。我国SBS产能过剩，市场竞争将更加激烈。今后应该慎重新建或者扩建产能，而是应该着力于完善现有生产技术，加快新产品和新技术的研究，不断提高产品质量，降低生产成本，在满足国内需求的同时积极开拓国外市场。

Supply and Demand Status and Development Prospect Analysis of SBS in China

With the completion and operation of several new or expanded units，the production capacity of styrene-butadiene-styrene block copolymers（SBS）in China increased steadily.In 2023，domestic SBS production capacity achieved 1 615 kt，and the apparent consumption achieved 915 kt.In 2028 the production capacity and consumption will reach about 2 000 kt and 1 000 kt respectively.China’s SBS is overcapacity，market competitiveness will be more intense.In the future，domestic SBS enterprises should be careful to build or expand new production units，but focus on constantly improving existing production technologies，accelerating research on new products and new technologies，constantly improving product quality，reduceing production costs，and actively exploring foreign markets while meeting domestic demand.
