The development of PVC profile in our country

History of PVC profile in China

PVC profile products experienced the lead-in period and high-speed development period, from the time, can be defined as the 20th century 80's -90's mid and 1995 -2002 or so. After 2003, PVC profile industry entered a transition period. In the introduction period of products: manufacturers generally pursue low cost, simplify the section of doors and Windows profiles, a large number of calcium carbonate filled in the formula, resulting in low product performance, a lot of quality problems affect the promotion of products.

Since 1995, A GROUP OF powerful enterprises began to digest and absorb the technical essence of foreign European profiles, developed their own series of doors AND Windows, become the leading domestic plastic doors and Windows, promote the technological update and development of doors and Windows, but also make the whole industry has been unprecedented development and high-speed growth. After entering the product maturity period, that is, since 2003, many drawbacks began to reflect, excessive profit rate led to excessive blind investment, so that the industry's comprehensive capacity of nearly 3 million tons, far higher than the market demand; Many new investors do not start with product innovation and technological innovation, but simply imitate, or even cut corners, fake and shoddy goods, and the industry market competition is in an unhealthy state. Raw material market prices continue to rise, exacerbating this unhealthy competition, so that some enterprises in a predicament, production or semi-production state. [1]

Current situation of PVC profile industry

This industry also exists a large number of production enterprises (nearly 400), small output capacity (2.8 million tons), small demand (in 2003 the national profile sales of 1.2 million tons), production capacity can not fully play the contradiction, annual output of more than 20,000 tons of enterprises less than 10, product quality level is uneven, inferior products still have a market, Industry quality and technical standards are too low, not conducive to technological progress, leading to the comeback of alternative aluminum. The high-end market (30%) is occupied by foreign brands, while the middle and low market is unprofitable and competitive, and the final pattern has not yet been formed.

From the factory distribution, among the 392 profile manufacturers, 37% are in the southeast, 12% in Shandong, 17% in the central, 19% in the northeast and 15% in the west. From THE division OF production capacity in 2003, the national production capacity of 2.8 million tons, Shandong region 9%, the central region 1%, the Northeast region 32%, the west region 7%, the Southeast region 39%.

Development prospect of PVC profiles

During the Ninth Five-Year Plan period, China achieved an average annual economic growth rate of 8%. In the Tenth Five-Year Plan, it is clearly pointed out that further strengthening the infrastructure construction and implementing the urbanization strategy provides a broad space for the development of the national building materials industry.

Current situation of PVC pipe industry

As one of the products of the development of science and technology, PVC pipe can be seen in daily life. In Europe, the growth rate of plastic pipe was 8% from 1980 to 1990, and production reached 3.5 million tons in 2001, of which PVC pipe accounted for 60%. The United States produced 1.6 million tons of plastic pipe in 1985 and about 3.6 million tons in 1999, of which PVC pipe accounted for 78 percent. The first UPVV flaring pipe in China was born in 1983 in Shenyang Plastic Factory (the predecessor of Shenyang Jiuli), since then, the Chinese mainland has the production capacity of PVC supply and drain pipes. The late 1990s is a period of rapid development of PVC pipeline in mainland China. During the period, some factories with an annual capacity of more than 50,000 tons have been built and put into operation, and more than 30 PVC pipe factories with a production scale of more than 10,000 tons have been established. By 2013, the annual production capacity of plastic pipes was 2 million tons.
