Since the Ministry of Commerce announced on June 6th that Nantong Xingchen Synthetic Material Co., Ltd. v. dumped the PBT from Japanese and Chinese Taiwanese manufacturers, the future direction of the PBT industry and the market has attracted widespread attention in the industry. Recently, the reporter interviewed the relevant experts of the China National Association of Engineering Plastics Industry, Zheng Zheng, on issues concerning the development of PBT industry, market demand and market environment.
Product: Leader in independent innovation of engineering plastics
PBT (polybutylene terephthalate) is one of the five general engineering plastics, with high temperature resistance, moisture resistance, abrasion resistance, oil resistance, chemical corrosion resistance, good electrical insulation properties, excellent thermal properties, mechanical properties and processing performance It can be used for spinning and preparing fiber jackets and masterbatches. Since there are crystalline regions and non-crystalline regions in the aggregate structure of PBT, it is easy to modify it by adding other substances, thereby giving it various functions. After PBT has been enhanced and modified, it can be widely used in automotive, electronic and electrical, textile, mechanical equipment and precision instrument components, communications, lighting and other high-tech fields.
It is understood that research on the synthesis of PBT in China began in the 1970s. The Beijing Chemical Research Institute and the Shanghai Resin Research Institute have all conducted development research. In 1992, Nantong Synthetic Materials Factory (now Nantong Xingchen Synthetic Material Co., Ltd.) integrated the continuous process technology developed by Chenguang Chemical Research Institute with advanced foreign equipment, and built a 5,000 tons/year transesterification method. The production equipment of methyl ester as raw material became the first continuous transesterification PBT production device in Asia; in 2003, the company also acquired a set of 10,000 tons/year continuous direct esterification device using Zhangjiagang's imported process equipment. The supporting level and consumption index are basically the same as those of foreign companies. In 1997, Yizheng Chemical Fiber Group Engineering Plastics Factory introduced the German Jema company's process technology and equipment, and built the world's first industrialized continuous direct esterification method (using refined terephthalic acid as raw material) production equipment, with an annual production capacity of 20,000 Ton. Therefore, PBT is the only one of the five major engineering plastics in China that has successfully relied on domestic independent technologies to achieve industrialization.
Status: Rapid growth in demand
With the rapid development of China's national economy, especially the rapid development of the downstream electronics industry and the automotive industry, the rapid growth of PBT market demand has been promoted. In 2002, the consumption of PBT resin in China was 26,100 tons, which was 27% higher than in 2001; in 2003, it was 34,700 tons, which was an increase of 47% compared with 2002; in 2004, it was 4.52 million tons, compared with 2003. Increased by 30%. It is estimated that the consumption of PBT in China will be about 55,000 tons in 2005.
However, at the same time as the rapid growth of demand, domestic PBT production capacity is largely idle, and imports have increased rapidly. In 2002, the import volume was 14,500 tons. In 2003, it increased to 21,000 tons, and in 2004 it increased to 25,000 tons. In 2005, the import volume is expected to reach 33,000 tons.
In 2004, the domestic PBT production capacity reached 60,000 tons while the output was only 20,000 tons. In addition to the normal production of Yihua and the intermittent production of Nantong Star, other manufacturers such as Beijing Fanwei, Jiangyin Sanfangxiang Group, and Shijiazhuang Chemical Fiber Plant have ceased production. In recent years, the growth rate of domestic production is lower than the growth rate of demand, and it is in a very abnormal state.
Expectations: Call for Fair Market Environment and Policy Support
The industry generally believes that the reason for the abnormal development of PBT production and demand is the impact of foreign low-priced imported products. Due to PBT's production of raw materials -- dimethyl terephthalate or terephthalic acid and 1,4-butanediol, the price of crude oil has been subject to higher prices, especially 1,4-butanediol. Spandex is the main raw material, the price is still high, so the production cost of PBT is quite high. However, due to the impact of imported low-priced PBT products, domestic PBT prices have remained low. Due to the pressure of cost, the domestic PBT producers are in a state of loss. Even the big manufacturer of PBT, Nantong Xingchen, once had to stop production and purchase the imported PBT products for post-processing. Therefore, low-priced imports of PBT products have seriously damaged the normal development of China's PBT industry, posing a serious threat to the long-term interests of the downstream industries. To this end, China's relevant enterprises have filed anti-dumping claims, and they hope that the relevant state departments will, based on the facts, make a correct decision in accordance with relevant laws and regulations.
Industry insiders also pointed out that the technical content of engineering plastics is high and related to the improvement of national security and the quality of life of the people. The development of the domestic engineering plastics industry is very difficult. It first encountered foreign technology blockades, and later suffered low-cost competition and dumping damage from abroad. Therefore, the state should strengthen its policy support for the engineering plastics industry, including PBT, to help the domestic engineering plastics industry enhance its independent innovation capabilities and protect the healthy development of national industries.
