Market Characteristics And Trend Analysis Of Unsaturated Polyester Resin For 2013 Industry

< p > < strong > foreign product application is concentrated in the high-end market < /strong > < /p >.

< p > 2013, domestic industrial unsaturated polyester resin output was concentrated in Jiangsu, Guangdong, Fujian, Shandong, Zhejiang, Hebei and so on.

Jiangsu continued to lead the country, with output reaching 1 million 20 thousand tons, followed by Guangdong, whose output exceeded 300 thousand tons; Fujian's output exceeded 250 thousand tons; the scale of enterprises in Zhejiang was small, and the EIA was shut down for many years, and production declined in recent years.

< p > 2013, the output of foreign enterprises in China's unsaturated polyester resin reached 190 thousand tons, and the application was concentrated in the high-end market.

The largest domestic production enterprise is still the Asia bond paint company, achieving 240 thousand tons throughout the year, followed by Tian He, Futian, Hua Xun, Ze yuan, Fang Xin and so on, with a total output exceeding 650 thousand tons.

From the analysis of the overall technical level of industrial unsaturated polyester resin, Jiangsu and Shanghai are still the largest R & D and manufacturing OEM bases in the country.

SMC/BMC resin, wind power resin, desulfurized resin, shipbuilding resin and structural resin of foreign enterprises in Jiangsu still lead the country, and have led to the technological upgrading of Jiangsu's entire industry.

As the national OEM base, Jiangsu's main output varieties are low cost benzene resin and air dried DCPD resin, and two kinds of OEM resin can reach about 100000 tons.

In recent years, the state attaches great importance to environmental protection, the growth of vinyl ester resin has accelerated, the size enterprises in Jiangsu and Shanghai have reached more than 20, and the initial output of the country has been 43 thousand tons.

It is worth noting that in order to reduce the cost, a modified vinyl ester resin appeared in the market. Its corrosion resistance is poor, its use period is short and the cracking phenomenon has damaged the customers and the market.

< p > in recent years, with the innovation of glass fiber manufacturing technology, the continuous development of new glass fiber varieties with high strength and high modulus has led to the research and development of new varieties of unsaturated polyester resin.

Fiberglass composite materials are not only facing the structural "thin" design and lightweight sandwich structure design, but also facing functional additives and powder compounding, thus promoting the glass fiber products from the past traditional two element composite into the multiplex composite, reducing the amount of resin, increasing the fiber consumption, and greatly improving the performance of the products.

For example, megawatt wind turbine blades, Danish LM China Co., Ltd. used high performance glass fiber and unsaturated polyester resin on the 73 meters of blades. 25M above luxury class yachts designed with unsaturated polyester resin sandwich design, also showed the advantages of light weight, high speed, low energy consumption and high impact.

< p > domestic high performance unsaturated polyester resin is in the state of high-speed development to adapt to the high-end market demand of high performance FRP composites.

Lightweight requirements such as light rail pit, high-speed railway, boat vehicle and wind turbine blades have promoted the development of unsaturated polyester resin to low viscosity, low heat release peak, high strength, high fatigue resistance, high flame retardancy and so on. Lightweight structure and low-density, injection grade SMC/BMC resin development are also developed.

< p > in addition, trenchless tank repair, double wall underground oil storage tank, surface gas storage station, offshore engineering drilling platform derrick, container plate, high-speed law enforcement boat, patrol boat, fishing boat, offshore wind power and seawater desalination will select high performance unsaturated polyester resin.

Because of the environmental protection effect, the application of water-soluble unsaturated polyester resin is also gradually heating up.

In the aspect of curing technology, the thin layer unsaturated polyester resin coating curing technology is also pferring to the light curing technology of the thin wall < a href= "http://www.91se91.com/news/index_c.asp" > glass fiber < /a > composite material.

Problems such as < p > strong > serious pollution environment need to be solved < /strong > < /p >.

< p > China's unsaturated a href= "http://www.91se91.com/news/index_c.asp" > polyester resin < /a > industry will face new opportunities in the next ten years. This opportunity comes from two aspects: first, China is the largest developing country in the world and has to catch up with developed countries such as Europe, Japan and other developed countries. China's glass fiber composite industry needs to pfer from a low level to an advanced one.

From energy and low carbon two aspects, the market needs a large amount of glass fiber materials and products; two, the continuous innovation of glass fiber and high performance synthetic fiber in the world and China, affecting the urgency of upgrading the technology of unsaturated polyester resin in our country. The development of high performance glass fiber has made the developed countries abandon the production of carbon fiber T300, and therefore promote the performance of high performance unsaturated polyester resin to attack the emerging market.

< /p >

< p > however, at present, only more than 160 industries in China use unsaturated polyester resin < a href= "http://www.91se91.com/news/index_c.asp" > manufacturing enterprises < /a >, with less than 20% of scale level, less than 15% of enterprises with independent innovation capability, and three of them are civilian run enterprises and private enterprises.

Many small and medium sized resin enterprises waste waste water and waste gas at random and pollute the environment; the enterprises are seriously lacking R & D personnel and testing equipment, the formula "plagiarism" and "stealing peach for plum", in order to reduce the resin performance to "meet the" market "low cost"; the production technology is lack of fine and safe management, the size accidents are constantly appearing, the testing of raw materials and products is not necessary and the quality of the resin is unstable.

< /p >

< p > unsaturated polyester resin industry and glass fiber industry are just like two melon on ivy, which is an indivisible whole.

Nowadays, China's industry composite materials industry is facing a new period of pformation and upgrading. China's unsaturated polyester resin industry must speed up follow-up. Conditional enterprises should take foreign capital enterprises and domestic advanced enterprises as examples, establish and perfect the technology development system and technology test system, face the market economy, help downstream enterprises to make good use of materials, make products, set standards and participate in competition.
