Anhui Quanchai Group Co., Ltd. is a well-known large-scale state-owned enterprise group with assets of more than 1.6 billion yuan. It is a leader in the production of single-cylinder diesel engines in China. As a listed company, Quanchai Group has a complete marketing network covering 30 provinces, municipalities and autonomous regions, with production and sales ranking among the best in the country. Why is the new product performance seminar and promotion meeting of Quanchai Group not selected in the enterprise resident or other big cities, but chose a county-level city in other provinces - Laizhou? The introduction of the promotion organizer unraveled the mystery. It turned out that the reason why Anhui Quanchai Group first landed its new products in Laizhou was mainly optimistic about the broad market potential of engineering machinery engines in Laizhou.
In recent years, the construction machinery manufacturing industry, mainly dump trucks, mini excavators and loaders, has developed rapidly in Laizhou City. The city's large and small dump trucks, mini excavators and loader manufacturers have sprung up and developed rapidly. It has become a key production area of ​​construction machinery in the country. In particular, Shahe Town, which has a relatively strong manufacturing base, has concentrated nearly 60 construction machinery manufacturers. In order to meet the new market challenges, Laizhou's construction machinery enterprises have adjusted their development strategies in a timely manner, taking the road of joint industry and common development. At the end of 2004, the Shahe Construction Machinery Chamber of Commerce was established to carry out information guidance, technological innovation, business exchange and training in construction machinery enterprises. The establishment of the Chamber of Commerce has laid a good foundation for further improving the overall development level and comprehensive competitiveness of the whole industry, and has formed a group of small construction machinery manufacturing enterprises that are very influential in the country, mainly Laigong and Lugong. . The products cover dozens of varieties such as dump trucks, loaders, excavators and mixing stations.
The rapid development of engineering manufacturing has also led to the rapid rise of related industries in Laizhou, forming an industrial chain integrating equipment manufacturing, parts processing, vehicle assembly and sales services, and promoting the manufacturing of the city's manufacturing industry from traditional primary products. The transformation of the finished product manufacturing in the depth. At present, the production and sales of dump trucks in Laizhou have accounted for more than 70% of the national market. Small loaders account for more than 50% of the national market, and the annual output value of construction machinery industry can reach 500 million yuan.
Styrene-isoprene block copolymers (SIS) are large volume, low priced commercial Thermoplastic Elastomer which are produced by living ionic copolymerization by sequentially introducing styrene, 2-methyl-1,3-butadiene (isoprene), and styrene into the reactor. Tpe Thermoplastic Elastomer content typically varies between 15 and 40 percent. When cooled below the melting point, SIS`s with a low styrene content phase-separate into nano-sized polystyrene spheres imbedded in an isoprene matrix whereas an increase of the styrene content leads to cylindrical and then to lamellar structures. Thermoplastic Polyamide Elastomers styrene domains function as physical crosslinks which provide mechanical strength and improve the abrasion resistance, while the isoprene rubber matrix provides flexibility and toughness. The mechanical properties of SIS elastomers with a low styrene content are similar to those of vulcanized rubbers.
As a kind of Rubber And Plastic,unlike Pvc Resin,Eva Resin or Pvc Paste Resin,Sis Rubber are often blended with tackifier resins, oils and fillers, Thermoplastic Silicone Elastomer allows for a versatile modification of product properties or they are added to other thermoplastic polymers to enhance their performance.
Thermoplastic Elastomer Sisare widely used in hotmelt adhesives, sealants, gasket materials, rubber bands, toy products, shoe soles and in bitumen products for road paving and roofing applications.
