Glass fiber is the largest amount of engineering plastic materials, the development of engineering plastics can not be separated from the glass fiber industry support and assistance. In the early period of reform and opening up, engineering plastics had just started to develop. The two chemical research institutes in Beijing have cooperated with the 251 factory at the same time. Thirty years later, both glass fiber and engineering plastics have had tremendous development. They have become an indispensable and important industry in the development of the national economy, and have also created a batch of glass fiber enterprises.
In recent years, there has been an increase in the use of glass fibres for engineering plastics, and usage has also increased year by year. In 2005, the domestic consumption was 70,000 tons. In 2006, it reached 90,000 tons. In 2007, the amount used exceeded 140,000 tons. The amount of glass fiber reinforced by engineering plastics increased by almost 300% in three years. It is estimated that the demand for domestic engineering plastic resin in 2010 will be 500,000 tons of nylon resin, 1.5 million tons of polycarbonate, 300,000 tons of polyformaldehyde, 200,000 tons of PBT resin, 50,000 tons of polyphenylene ether resin and 33,000 tons of special resin. . The total demand for engineering plastic resin will reach 2.6 million tons.
At present, the domestic plastics modification market has a capacity of about 3 million tons, of which about 900,000 tons of engineering plastics; by 2010, demand is expected to reach 4.6 million tons, and engineering plastics are estimated to be around 1.5 million tons. According to this development trend, the demand for glass fiber for engineering plastics by 2010 should be around 210,000 tons. According to the type, the number of nylon fibers should be approximately 60,000 tons; the amount of PBT yarn used should be 45,000 tons; Yarn quantity is 40,000 tons; ABS yarn quantity is increased by 10,000 tons; Polycarbonate yarn is increased by 10,000 tons; Modified polyphenylene ether yarn quantity is 10,000 tons; other 35,000 tons.
With the changes in the market, the proportion of different types of glass fiber will also change, such as short cut yarn, long glass fiber reinforced special yarn, environmental protection yarn, etc. will increase the proportion; the advantages of the pool kiln yarn comparison Falafel will gradually show come out.
Due to the large number of foreign companies entering the competition is very serious. They rely on their advantages in technology, capital, and services to compete with domestic companies for the market. Domestic companies are faced with international competition. The development and changes in the future will not simply fill the gaps in the industry, master several technologies, and possess advanced equipment. Instead, it will require the company’s overall technological, quality, economic, and other indicators to directly participate in the competition among international giants, and whether they can win. It depends on the overall strength of the contest. The rapid development of engineering plastics has benefited from the advantages of cost-effectiveness and has rapidly developed in place of other materials. With the continuous development of technology, it has brought about market opportunities for general-purpose plastic engineering and low-cost engineering plastics.
