Under the completely competitive market structure in China, the cost is the most important factor that affects the competitiveness of enterprises. As a result of industry characteristics, raw materials and energy occupy a high proportion in product cost. The cost of oil ethylene is mainly affected by the impact of the price of petroleum; calcium carbide production cost is mainly affected by the cost effect in general, calcium carbide, calcium carbide cost accounted for about PVC 70% of the cost, and the cost of electricity has accounted for about 60% of the cost of calcium carbide, because China is rich in power resources in the west, the electricity price is relatively low, compared with the production Eastern Enterprises calcium carbide production enterprises, the calcium carbide method has certain advantages in terms of cost. With resource endowments, supporting the production of calcium carbide enterprises, will build more solid cost barriers. Industrial policy barriers To promote the upgrading of chlor alkali industry in the industrial structure, regulate the development of the industry, in accordance with the principle of sustainable development to optimize the layout and orderly development, adjust the structure, save energy, protect the environment, safety production, technological progress, the national development and Reform Commission issued the "formulation (chlor alkali caustic soda, PVC) industry access conditions", and since the beginning of December 1, 2007: in the industrial layout for new chlor alkali production enterprises should be close to the resources, the energy area, the eastern region in addition to the relocation of enterprises outside the principle of caustic soda project is no longer the new carbide PVC project and its matching; technology requirements for construction and reconstruction of the calcium carbide PVC project must be simultaneously supporting the building of carbide slag cement and carbide slag comprehensive using the device access conditions; from the index of energy consumption and environmental standards for new projects. The adjustment of industrial policy greatly improves the threshold of capital, technology, talents and resources in the chlor alkali industry EVA is a copolymer of ethylene and acetic acid. The Chinese chemical name is ethylene vinyl acetate copolymer (ethylene vinyl acetate copolymer). The English chemical name is Ethylene Vinyl Acetate Copolymer. The application field of EVA is quite extensive. The market consumption in China is increasing year by year, especially in shoemaking industry, which is applied to middle and high grade shoes, mountaineering shoes, slippers, sandals, soles and interior materials.

Ethylene vinyl acetate (VA) content in 5%-40%, and polyethylene (PE) compared to EVA due to the molecular chain of the vinyl acetate monomer, thereby reducing the high crystallinity, improved toughness, impact resistance, filler compatibility and heat sealing performance, is widely used in foam material, functional films, packaging mold, hot melt adhesive, wire and cable and toys and other fields.
