The demand for unsaturated polyester resin in Chin

The demand for unsaturated polyester resin in China is gradually rising

with the continuous strengthening of infrastructure construction and the vigorous expansion of other consumption fields, the demand for unsaturated polyester resin in China is gradually rising. According to experts' estimates, the demand for unsaturated polyester resin in China will reach 1million tons by 2005. Statistics show that the production of unsaturated polyester resin in China has reached 583000 tons in 2002, an increase of 11% over 2001. The import volume reached 149000 tons, the export volume 4556 tons, and the actual domestic consumption reached 722000 tons. In the same year, Japan produced 194000 tons, and the United States exported 31500 tons. The usage 71 included the load abetting disk and the vernier caliper of the elongation value of the sample, with an automatic deformation curve recording device 960000 tons, which is lower than that of China. In 2002, the unsaturated polyester resin production areas in China were still concentrated in Jiangsu, Guangdong, Zhejiang and Fujian in the four southern provinces. Among them, 190000 tons are from Jiangsu, 130000 tons from Guangdong, 70000 tons from Zhejiang and 60000 tons from Fujian. The total output of the four provinces is 450000 tons, accounting for 80% of the national total. In 2002, researchers spent three years developing such new composite materials. The long figure shows that the demand for unsaturated polyester resin in China is continuing to expand; From the perspective of regional distribution, unsaturated polyester resin enterprises in the north are shrinking, while enterprises in the south are ahead in market-oriented, variety adjustment, new product development, low-cost operation, etc. In addition, under the influence of global economic integration, China's domestic polyester deep-processing FRP industry has a growing demand for unsaturated polyester resin with stable quality and excellent performance, and provides two markets at home and abroad with excellent products

it is predicted that the market of unsaturated polyester resin will change greatly in 2003. The fluctuation of the price of chemical raw materials will directly affect the price of unsaturated polyester resin in 2003. The price of styrene continues to rise due to insufficient domestic production. In 2002, the domestic demand for styrene was 2.9 million tons, while the domestic output has reached 900000 tons, requiring a large number of imports. According to expert statistics, the output of unsaturated polyester resin in China has exceeded 350000 tons from January to August 2003. Relevant experts believe that the scale of use of unsaturated polyester resin in China has been firmly in the leading position in the world. An important feature of the demand development of unsaturated polyester resin in China is that the product structure of products has changed greatly. Reinforced and non reinforced aluminum alloys for aviation have low density and good corrosion resistance. The proportion of strong resin has changed from 70:30 to 55:45 in the second half of 2002. In particular, the amount of non reinforced resin increased rapidly, reaching 340000 tons, of which the amount of non reinforced resin required for polyester crafts and polyester artificial stone is very promising

unsaturated polyester resin. Now electronic universal testing machine is one of the main varieties of thermosetting resin that every manufacturer needs very much. It is widely used in industry, agriculture, transportation and other fields. Unsaturated polyester resin is mainly divided into two series: reinforced and non reinforced. Reinforced products mainly include cooling towers, boats, chemical anti-corrosion equipment, vehicle parts, doors and windows, activity rooms, sanitary equipment, food equipment, entertainment equipment and sports equipment; Non reinforced products mainly include furniture coatings, Polaroid boards, buttons, imitation ivory, imitation jade crafts, artificial marble, artificial agate and artificial granite
