Baling Petrochemical: SEBS marketing has become a hot spot in the market

in the first half of this year, the sales volume of SEBS products of Baling Petrochemical synthetic rubber division, the largest styrene thermoplastic elastomer (SBC) manufacturer in China, exceeded 4800 tons, exceeding the sales volume of last year. At the same time, the monthly output of this unit with an annual capacity of 10000 tons is stable at more than 900 tons, and the current operation is stable. The production and sales of the device meet the standards again. SBC has excellent performance and continues to develop thermoplastic elastomer (TPE), which has the characteristics of both plastic and rubber, and is known as the third generation of synthetic rubber. SBC (also known as styrene block copolymer) plays an important role in TPE. It is a thermoplastic elastomer with the largest output and the fastest development in the world. SBC is also called lithium polymer because it uses organic lithium as initiator in its production process. SBC can be divided into styrene butadiene styrene block copolymer (SBS), styrene isoprene styrene block copolymer (SIS) and their corresponding hydrogenation products - hydrogenated SBS (SEBS) and hydrogenated SIS (SEPs); According to the structure of polymer, it can be divided into two types: linear and star; It can be divided into pure materials (non oil filled and oil filled) and various filled granular materials (i.e. mixtures) according to their properties. According to the proportion and molecular weight difference of various hard segments and soft segments, it can be divided into several brands

sbc has excellent tensile strength, large surface friction coefficient, good low temperature resistance, excellent electrical properties and good processability. Due to its excellent physical properties, SBC has developed rapidly, and has become the largest thermoplastic elastomer in consumption at present, accounting for% of the total consumption of all kinds of thermoplastic elastomers. SBS accounts for more than 70% of SBC, and is the largest SBC product in output; SIS accounts for about 20% of SBC consumption; SEBS based hydrogenation products account for about 7% of SBC consumption

compared with other thermoplastic elastomers, SBC has the characteristics of high strength, softness, small permanent deformation, and rubber elasticity. It is suitable for being used as adhesive and sealing material for hot-melt processing. It is widely used in shoe making, liquid sealing materials, wires, cables, auto parts, medical device parts, household appliances, adhesives and other fields. Among them, SBS is mainly used as shoe-making, plastic and asphalt modifier; SEBS is mainly used in adhesives, medical supplies, automobiles, household appliances and automated office equipment; Sis and its hydrogenated product SEPs are mainly used for the modification of hot-melt adhesives and asphalt, and their main uses vary in different countries and regions. SEBS consumption grows rapidly

in SBC, although SEBS accounts for a small proportion of consumption, the characteristics of SEBS make it a hot spot of research and development in recent years, and its consumption growth accelerates. According to insiders, SEBS' annual consumption in the United States is about 10000 tons, and is expected to grow at a rate of 3%; In Western Europe, SEBS' annual demand is about 30000 tons, and its growth rate will reach%; In Japan, the annual demand for SEBS products is also about 10000 tons. With the demand of other regions in the world, it is estimated that the annual demand for SEBS hydrogenation products in the world is about 150000 tons

it is understood that with the growth of demand, the world's major SEBS hydrogenation product manufacturers have some capacity expansion plans at the 7th China smart city exhibition held in Ningbo, Zhejiang Province in early September. For example, Kraton has increased kratong's production capacity by 10000 tons/year in 2005, set up a multi-functional customer service center in Shanghai in 2007, and plans to build a kratong production plant in the Asia Pacific; In 2007, the Japanese Cola company expanded the annual production capacity of the United States from 12000 tons to 18000 tons; Dynaso also plans to expand its plants in Spain and Mexico. Industry analysts estimate that the production capacity in the Americas is about million tons, that in Europe is about million tons, and that in Asia is million tons, a total of million tons/year. While expanding capacity, manufacturers also attach great importance to product innovation. At present, the main research direction is to develop PVC substitutes, soft vulcanized rubber substitutes and new adhesive materials. At present, only the Baling Petrochemical synthetic rubber division under Sinopec has a SEBS production line with an annual output of 10000 tons in China, and its (phase II project) annual output of 20000 tons is under expansion and transformation. According to information, the 20000 ton SEBS device of taixiang in Nantong will be put into production in the middle of this year. It is reported that there are already test products for users to try. Chinese Mainland is one of the regions with the fastest development of SEBS application, which can be seen from the growth of its import volume. According to official statistics, the import volume of hydrogenation products was about 6000 tons in 2005, and increased to about 10000 tons in 2006. At present, the applications of SEBS in China mainly focus on soft contact coating materials, low hardness elastomers, compatibilizers for SBS and other materials. With the development of economy and the market's demand for product quality to improve the mechanical properties of gb/t 3098.7 (2) 000 fasteners and self extruding screws, the amount of SEBS in the existing elastomer must be increased, which alone will increase the market capacity of more than 10000 tons. With the development of various new uses, such as replacing soft PVC, the modification of various general plastics, the promotion of the application of sealing strips and wires and cables, and the application of lubricant viscosity index improvers, experts predict that the domestic SEBS market capacity will further increase in five years. In this regard, domestic enterprises are facing not only development opportunities, but also many challenges, especially in product quality and stability. Quality improvement and production and marketing standards are synchronized

it may take a long process for a new product to be recognized by the market from R & D to industrialized production, and then to launch on the market. However, the experience of Baling SEBS of Baling Petrochemical synthetic rubber division took less than two years

the thermoplastic elastomer SEBS complete set technology development project of the Division has been included in the National 863 plan, with an annual output of 20000 tons of Mao series hydrogenation SEBS complete set technology development project, which is one of the ten key scientific and technological research projects of Sinopec. In March, 2006, the business unit completed and put into operation the first domestic 10000 ton SEBS industrial production device with independent intellectual property rights. The SEBS products of multiple brands produced by the device filled the domestic gap and can replace imports and participate in international competition, further improving the market share and influence of domestic SBC products. After the 10000 ton SEB plant rather than oil manufacturing s industrial plant is put into operation, there are some bottlenecks that need to be overcome in the operation process: quality problems such as color change and odor affect the market expansion of SEBS products; Smooth operation is subject to long-term running in of equipment and process; wait. In this regard, Baling Petrochemical synthetic rubber division gives full play to the advantages of production, marketing and research integration, and organizes a research team with nearly 100 professional technicians to track the process status, product quality, user use and other links in the whole process. In fact, it can not achieve zero pollution. Through careful organization of small-scale and pilot tests, on the one hand, it puts forward more than 10 specific and implementable opinions and suggestions for optimizing production and improving quality of the device, On the other hand, develop new SEBS products. After developing the basic formula of SEBS barrier fuel and the special SEBS new brand in the early stage and promoting its application in the cable field, two SEBS new brand products have been developed and trial production has been carried out. Substantial progress has been made in the SEBS new product development project applied to lubricant viscosity enhancement. After more than 300 experiments, the technicians of the Department found the root causes affecting the quality of SEBS and put forward countermeasures. At the same time, in view of the high consumption of the unit and the high product cost, the business division also focused on the process optimization and equipment defect elimination of the unit, and carried out a series of defect elimination rectification and optimization. Only the optimization of the catalyst addition method effectively reduced the production cost of SEBS. The localization transformation of the later processing equipment also laid a solid technical foundation for the further improvement of the unit capacity. Technological innovation not only makes the equipment operate more and more normally, but also improves the quality and output of SEBS steadily. In May this year, SEBS output reached 910.67 tons, reaching the standard of that month. At the same time, in order to get close to the market and expand sales, on the one hand, the business division actively seeks customers, understands the dynamics of downstream enterprises through information inquiry and discussion with dealers, communicates directly with them, sends samples to manufacturers for trial, provides technical guidance, and tracks the trial situation in a timely manner; On the other hand, the marketing personnel of the Department are in close contact with the scientific researchers to feed back the product quality information and the research and development information of new products in the market in a timely manner, and actively seek solutions to the difficulties and problems of customers in the process of trial and use of products together with the scientific researchers. In the past six months, the scientific research and marketing personnel of the Department have provided after-sales technical services for users for eight times. By the end of June, the Department had sold 4820.675 tons of SEBS products this year, including 4341.27 tons of linear brands 501, 502, 503, 561 and 563, and 355.085 tons of star brand 602, with a market share of more than 60% in China
