Glass fiber is the most consumable materials engineering plastics, engineering plastic fiberglass industry¡¯s development is inseparable from the support and assistance. Reform and opening up, engineering plastic has just started early development, Beijing institute of two chemical plants and 251 almost simultaneously carried out of fiberglass. After 30 years, fiberglass and engineering plastic two industries have tremendous development, has become a national economic development the indispensable important industry, also made a fiberglass enterprise.
In recent years, used for engineering plastic fiberglass reinforced increase dosage, varieties also is increasing year by year. In 2005, the domestic usage for 7 million tons in 2006, up to 9 million tons in 2007, more than 14 million tons, the dosage of 3 years for engineering plastic fiberglass reinforced almost quadrupled volume growth. By 2010, China is expected to engineering plastic resin demand is respectively: nylon resin 50 million tons, The polycarbonate 1.5 million tons, Gather formaldehyde 300 thousand tons, PBT resin 20 million tons, Styrene resin 50,000 tons of ether, Special resin 3.3 million tons. Engineering plastic resin total demand will reach 260 million tons.
At present domestic plastics modification is about 300 tons of market capacity (not including cable modification and PVC materials, including modification is about 90 tons of engineering plastics, By 2010, demand of 460 million tons, is estimated at 150 tons of engineering plastics. According to the development trend of that by 2010, demand of engineering plastics in 21 e should tons, presses breed points to: nylon yarn is 6 million tons, PBT yarn quantity 45,000 tons, Reinforced polypropylene yarn volume 4 million tons, Enhance ABS yarn volume 1 million tons, Enhance the polycarbonate yarn 10,000 tons, Modified polystyrene ether yarn is 10,000 tons, Other 3.5 million tons.
Along with the changes in the market, the proportion of different varieties fiberglass changes, such as the short cut yarn, long yarn, environmental protection, enhance special glass fiber yarn proportion will increase, Yarn furnace drawing method of comparative advantage of crucible will gradually reveal.
Due to the foreign companies into serious competition. They relying on technology, capital and service for domestic enterprises, with the advantage of domestic enterprises, the market is facing the international competition. The development and change of the future, not simply fill the domestic blank, master several technology, advanced equipment, but the whole enterprise need technology, quality and economic indices, direct participation in international competition, the titans could win depends on the comprehensive strength. The fast development of engineering plastics, thanks to the advantages, and replace ratio of other materials and rapidly. With technology development, and project engineering, general plastic plastic low-cost brings market opportunities.
