     The new chemical material is an important branch of the new material industry, and it is the most active and potential development field of the basic chemical industries. The development of new chemical materials industry in the breakthrough of domestic resources "bottleneck", environmental protection, adjust industrial structure, keep oil and chemical industry stable, faster and sustainable development "promising". 2011 China's foreign dependence on crude oil has exceeded 55%, and three consecutive years exceeding 50% cordon, is expected to 2020 foreign dependence will reach 67%.Chemical Sheet
     The energy utilization ratio of domestic petrochemical industry is 15% lower than that in developed countries. Some Products unit energy consumption is 20%-30%; the structural contradictions of domestic petrochemical products are outstanding, and more than 65% of the gross output value is composed of primary processing products such as oil and gas extraction, refined petroleum, basic chemical raw materials and fertilizers, and can not meet the needs of related industries. At present, the domestic chemical new materials market has a huge market gap, the import volume occupies most of the domestic market share, the domestic chemical new materials overall self-sufficiency rate is around 56%, of which the fresh field of chemical materials self-sufficiency rate of only 52%, engineering plastics and special rubber self-sufficiency rate of only 35% and 30%. Generally speaking, chemical new material products will experience the product gross margin fluctuation and import substitution rate rising process. In the process of import substitution of new chemical materials, most of the products are not outstanding, some products are in short supply, the enterprise capacity expansion of mastering core technology can obtain the profit proportional to investment, most enterprises can achieve sustained and rapid growth. High barriers bring high returns, cutting-edge chemical new material products gross margin of more than 70%, far more than 15% of the bulk of chemical industry average profit.Chemical Sheet
     Chemical materials are divided into metallic materials and non-metallic materials two categories. Chemical metal materials can be divided into ferrous metals and non-ferrous materials. Ferrous metal material mainly refers to iron and steel, most chemical machinery and equipment is made of cast iron and carbon steel. High alloy iron, high alloy steel (such as high ferrosilicon, high nickel iron and all kinds of stainless steel) and nickel, copper, aluminum, titanium, zirconium and its alloys, are also widely used in chemical production. Non-metallic materials are widely used in chemical industry, including plastics, rubber, glass, ceramics, enamel, non permeable graphite, etc. Plastic develops rapidly, corrosion resistance is excellent, the application of the most extensive, not permeable graphite not only heat, acid, but also high thermal conductivity, dosage is also more; ceramics, glass and other acid-resistant good, but brittle, and can not be made into large-volume equipment, so its own use is limited, but can be used chemical materials plastic, to be lined with metal surface, made of corrosion-resistant enamel equipment, lining (or lining) glass groove, cans and so on.Chemical Sheet
