At the same time, it is also an effective system of cadmium lead stabilizer, which has been partially banned in China due to its environmental hazards. According to the global ban on lead, lead and cadmium products will eventually be phased out in 2015. How to reduce the pollution and harm to environment and related personnel in the process of production and recycling of leaded metal PVC is an urgent problem to be solved. PVC plastic products in China and the international community is the trend of The Times, under the situation of the economic downturn, lead to lead-free, low product can also achieve plastic products of various economic and technical indicators, and easy to use, efficient, environmental protection and economy, it is also the many scientific research institutions and enterprises invest, strive to match a global environmental protection requirements, grab opportunities at home and abroad.

             The development of thermal stabilizer began in the 1980s. With the import of plastic processing machinery, various new technologies and products of plastic additives have also entered China. As used in the production of soft leather of LC - 90 (American hand meihua company production of cadmium zinc/push foam stabilizer), used for foam wall paper production high k/ca foam stabilizer (Netherlands akzo products), etc. These products bring us new processing concept and vision, and also the origin of the current thermal stabilizer variety and system miscellaneous in China. Objectively analyze the current domestic pattern of heat stabilizer if exclude lead, cadmium products are environmentally friendly products has formed by organic tin (including the distribution of products), calcium/zinc (is the distribution of products), rare earth compound with three big system, such as, of course, there were reports the research and development, the application of organic stabilizer. In terms of yield and identity, calcium/zinc products are the first. However, the compound multi-function organic tin stabilizer is a development trend of organic tin products, which is in line with the actual situation of China. Of course, rare earth products, especially the current rare earth/calcium zinc products are also a bright spot.

          Calcium zinc compound heat stabilizer is one of the world's recognized non-toxic, environmental protection heat stabilizer, and has the advantages of low cost, good lubricity, has a very broad space for development, composite calcium zinc stabilizers is to use the two have a synergistic effect, makes it the most active area in recent years in composite stabilizer. The world famous thermal stabilizer manufacturers all have this product launch. And domestic companies are catching up with different ways, such as wenzhou tiansheng, hebei grey, nanjing jinling, shenzhen sea, zhaoqing dinghu, companies such as in powder, paste, liquid, etc on the development and application of environmental protection products has achieved good results.

             Assisted the development and application of stabilizer is one of the highlights in agro-scientific research in the thermal stabilizer, this kind of organic compound phosphite, polyol, epoxy compound, beta diketone, stability of organic matter and inorganic kind the water talc, etc. In the research and application of organic stabilizer, the company has introduced the OBS, an organic product used in the processing of PVC hard products. Organic stabilizer can from organic alkali compounds, such as amino uracil, section two hydrogen pyridine and five ring 1 and 4 oxadiazoles derivatives such as extract, this kind of material with competitive price, at the same time in good performance with low mobility, low odor, prophase hue, excellent transparency. Organic stabilizers stabilizer due to inhibition of crosslinking, and the molecular chain in the processing of PVC products, processing time under high temperature and high shearing action, lead the class and is obviously better than the calcium/zinc soap stabilizer system and domestic institutions, enterprises as early as a few years ago have been put into a lot of people, goods, and has obtained certain achievements.

                Finally, we should also see, since the end of 2007 to now, due to the impact of the global financial crisis, the domestic economy is also a downward trend, plastic products have been hit by more late step, 2007 guangdong export toys for paint to paint the mattel recall events triggered by the global "crowd out" the wave of Chinese toys, about 2008 plastic bags "white pollution" caused by the "plastic limit order" two events caused the domestic toy production decline double-digit and seventy percent plastic bag factory. The thermal stabilizer industry is relatively unaffected, but it has a profound impact on the industry. Heat stabilizer industry with various metals such as lead, tin, stearic acid as main raw materials, such as price large fluctuation, raw material price trend barely stopped, enormous cost pressure for downstream processing industry, it basically in the condition of small profit for our fertilizer production enterprises, the gloom.

             However, we should also see that the central government has launched 4 trillion yuan of investment and 10 measures to expand domestic demand, which are good news for thermal stabilizers. Further analysis: in the ten measures to boost domestic demand, the construction of major water conservancy projects will be made of PVC pipes and membrane materials. In the government-subsidized housing project, the construction of low-cost housing, renovation of shanty towns, and plastic doors and Windows in the settlement of nomads are indispensable. In city network reconstruction, rail roads and airports and other major infrastructure construction of basic materials such as PVC wire and cable, the revitalization of the automobile industry, electronic information industry, will be more directly increase the demand for PVC plastic products and spare parts. These projects are huge investments, and many of the project funds are already in place and implemented. To sum up, the prospect of the hot stabilizer industry in this big cake is very attractive. Compared with the primary data of tiansheng's boss in the beginning of the year, he has made a clear prediction that the investment of the central bank will increase the consumption of PVC tube, and the increase is expected to be 5% to 10%. 

        At present, however, the growth rate of PVC rigid products will exceed 10%., of course, our country facing the heat stabilizer enterprises in recent years the inflationary pressure and operation of a variety of difficulties, from the deep analysis, is actually the small scale of enterprise management, talent, technology, funding shortages, comprehensive complications, prices rose is just a fuse. So in the face of the future may be continuing the price fluctuation of challenge and crisis, resources shortage, production enterprises in addition to relying on limited on its own resources to production management, market adjustment, the enterprise itself must be attention to technology research and development, increasing investment from the innovation, or through the enterprise mergers and cooperation, from to do bigger and stronger, doing fine, with a brand new concept to meet the challenge.
