EPS(1) cost barrier
PVC is a basic chemical raw material, and its product diversity is relatively small. 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.
Scale barrier
The investment in the production of PVC is large, the fixed cost is high, and the scale benefit is obvious. Large scale enterprises are in a more favorable position in negotiating with suppliers and are conducive to reducing the cost of raw materials. Enterprises with large production and sales have higher market share, with greater market influence and relatively easy access to customers. once the production and marketing of PVC enterprises have reached a large scale, the marginal cost will be gradually reduced and the ability to resist risk will be enhanced.
Capital Barrier
At the same time, along with the national safety and environmental protection increasingly stringent regulation, the construction unit must complete large-scale chlor alkali production environmental protection device (such as the corresponding line must be supporting equipment for producing cement carbide carbide slag etc.), more investment, most SMEs are unable to bear.
Therefore, the firms that invest in this industry must have strong capital strength and have certain financial barriers.
The demand for PVC in India's domestic market increased year by year, from 170 million tons in 2009 to 220 million tons in 2012. However, there were only 5 PVC production enterprises in India before, and the domestic production capacity was 1 million 250 thousand tons / year. India Finolex industry is the largest producer of PVC pipeline in India. Due to the imbalance between supply and demand, there is a big gap, so the average annual PVC import of India is 950 thousand tons. At the same time, the gap in India's vinyl is also increasing year by year, 722 thousand tons in 2011, 976 thousand tons in 2012, and 1 million 120 thousand tons in 2013. According to statistics, in 2012 4~9 months, India PVC imports mainly came from Korea, China, Taiwan, Germany, the United States, Mexico and other countries and regions, and the PVC imports from Korea and China and Taiwan were over 200 thousand tons.Rajesh Deshpande Speaking, India PVC downstream products with PVC pipes and accessories, accounting for 43% of the country's total products in the lower reaches of PVC. In the first six months of the 2012~2013 year, the downstream demand increased by 20% and the import volume increased by 50%. In accordance with this speed, by March 2013, the domestic market demand in India will reach 2 million 200 thousand tons, and the development speed of PVC pipes will reach two figures.

Polyvinyl chloride (PVC) melt belongs to a non Newtonian pseudofluid. The larger the shear velocity, the smaller the apparent viscosity, and the more sensitive the change. If the temperature rises, the viscosity will not decrease much. Even if the plastic is below the decomposition temperature, it will cause heat and oxidative degradation because of its high temperature for a long time, which will affect its performance. Therefore, to improve the fluidity of PVC melt, the main consideration is to increase the shear rate (increasing pressure). In fact, increasing the external force contributes to the movement of the macromolecules, reducing the Tf, and the large molecules can flow at a lower temperature.
Main uses
1. polyvinyl chloride special-shaped material
Profiles and profiles are the largest areas of PVC consumption in China, accounting for about 25% of the total consumption of PVC. They are mainly used for doors and windows and energy saving materials, and their applications in the whole country still have a substantial increase. In developed countries, the market share of plastic doors and windows is also the top priority, such as Germany is 50%, France is 56%, and the United States is 45%.
2. PVC pipe
In many polyvinyl chloride products, PVC pipeline is its second largest consumption field, accounting for about 20% of its consumption. In our country, the PVC pipe is PE pipe and PP pipe development early, many varieties, excellent performance, wide application range, occupies an important position in the market.
3. PVC film
The consumption of PVC in the field of PVC film is third, accounting for about 10%. After mixing and plasticizing PVC with additives, a transparent or coloured film with specified thickness is made by using three roll or four roll calender. The thin film is processed into a calendering film by this way. It can also be tailored, hot working packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. Wide transparent thin film can be used for greenhouse, plastic shed and film. Biaxially stretched thin films, which are characterized by heat shrinkage, can be used for shrinkage packing.
4.PVC hard wood and plate
PVC stabilizers, lubricants and fillers are mixed. After mixing, extruders can squeeze various caliber hard pipes, special-shaped pipes and bellows, which are used for down pipes, drinking water pipes, wire sleeves or staircase rails. The hot pressed sheet overlaps the hot press and can be made into hard plates of all kinds of thickness. The plate can be cut into the desired shape, and then the PVC electrode is used to weld a variety of chemical corrosion resistant tanks, air channels and containers with hot air.
