Nylon bias tire production dropped into the low-profit industry will be times

Nylon (or nylon) industry will enter a low-profit era. For some time to come, caprolactam and nylon cord fabric of the price of raw materials will remain at a relatively low level. This is from the May 31 end of the rubber industry's technological framework of the Forum on Chinese and foreign material learned.

It was the largest manufacturer of nylon fibers - Shenma Industrial Co., Ltd. General Manager Zheng Guang, because of market competition, high raw materials price shocks caprolactam, caprolactam and nylon 6, the price has been getting smaller and smaller, and even once appeared in nylon 6 Loss of collective enterprises. Nylon 66 due to the high cost of raw materials adiponitrile gradually rising prices, production efficiency of enterprises have begun to decline continuously.

Zheng said that the Canton, nylon tire cord fabric is the bias of the main frame materials, bias tire of the pace of development to a large extent determine the nylon cord to the market demand. In recent years, the tire industry adjust the product mix, many big companies out of bias tire production in the area. In the Meriones tire of the rapid rate of increase at the same time, the bias tire production began to decline. In the future, the demand for nylon cord fabric will be gradually reduced, nylon market will shrink.

Second, polyester, and other large-scale development of alternative raw materials, industrial nylon resulted in a greater impact. Polyester cord, in particular high modulus low shrinkage (HMLS) polyester cord, with a high modulus, low-heat shrinkable, good dimensional stability, behind the rate of loss of the advantages of small, can improve the performance tires, radial tire is the ideal child Body frame materials. In recent years, therefore, the polyester in the radial tire in the volume of applications quickly. In 2007, the National HMLS output year-on-year increase of 65.4 percent, nylon cord fabric output grew only 1.73 percent, from a nylon production reflects the impact of product substitution by large.

Third, the supply of raw materials increased risk of caprolactam. In 2007, domestic output of 304,000 tons of caprolactam, the demand for 776,000 tons, less than self-sufficiency rate of 40%. Caprolactam global operating rate has been maintained for many years in a row in more than 90%. As the new capacity of the international limited by the domestic technology and the associated infrastructure capacity limitations difficulty in a short period of time a significant increase in the risk of temporary parking caprolactam plant has increased year by year, will become increasingly tight domestic supply of caprolactam. Crude Benzol together with oil and product prices higher, prices may hexanolactam will continue to rise.

Zheng Guang said that the nylon business to develop ultra-high strength, lightweight, composite of a new type of nylon products, nylon cord as soon as possible upgrading of products.
