Ministry of Commerce recently announced that since July 22, 2011 onwards, made in Japan and Taiwan imported PBT resin (polyethylene terephthalate) anti-dumping measures applicable to the suspension. So far, China's PBT leave a five-year industry, trade protection, will face international competition.

   PBT from 1.4-butanediol (BDO) and terephthalic acid (PTA) or terephthalate (DMT) poly-condensation of the thermoplastic polyester resin. As one of five general-purpose engineering plastics, PBT resin, mainly used for modification of PBT, PBT spinning, film, PBT fiber jacket and other fields, can be modified in the widely used enhanced automotive, electrical and electronics, instrumentation, lighting appliances, household appliances, textiles, machinery and communications.

   In China, PBT is the most important areas of consumer electronics, in particular, with its production of connectors, switches, or car parts. In addition, PBT fiber atmospheric boiling dye, dyeing temperature is low, the pressure is low, with good stain resistance, especially to meet the high-elastic and soft market demand for textiles. China's PBT fiber production has begun industrialization, formed from polymerization, spinning, dyeing and finishing of textile processing to a complete industrial chain of clothing.

   Global PBT production mainly in the United States, Western Europe, Japan and South Korea. Among them, the Sa Bike Innovative Plastics is the world's largest manufacturer of PBT, production capacity reached 120,000 tons / year. Other major manufacturers include DuPont, BASF and Mitsubishi. Japan and Taiwan PBT producers significantly increase production capacity since 2002, on China's exports increased year by year, China's total imports now account for about 90%.

   Affected by the dumping of imported products, a few years ago domestic PBT device operating at only 15% to 25%, there is a general loss industry. In this case, the Ministry of Commerce decided July 22, 2006 onwards, made in Japan, Taiwan, China imposed the import of products ranging from 6.24% - 17.31% anti-dumping duties.

   Reflexive-dumping tax levy has been a substantial increase in domestic production capacity of PBT. Up to now, China's PBT total production capacity has reached 302,000 tons / year. Sinopec Yizheng Chemical Fiber Co., Ltd. is China's largest manufacturer of PBT, total production capacity of 80,000 tons / year, other major producers include China National Bluestar Group Nantong Star Material Co., Ltd. (6.8 tons / year), Xinjiang Blue Shan Tuen River Chemical Co., Ltd. (60,000 tons / year) and the economy of New Materials Co., Ltd. Jiangyin (3.5 tons / year).

   From the manufacturer point of view, the upstream and downstream integration has become a trend. In Yizheng Chemical Fiber, for example, is China's second largest polyester producer, with 100 tons / year of PTA production capacity. In the first half, the company 100,000 tons BDO project officially started construction. The project put into operation, the company can achieve self-sufficiency in raw materials PBT. In addition, Jiangyin, Nantong economic and so stars and their respective holding companies rely on the resources side, the industry has a strong competitive edge.

   On the other hand, according to chemical-line information, BDO project under construction across the country has five production capacity 275,000 tons / year, the basic operation in 2012, when domestic production capacity will reach 700,000 tons / year. This means that, PBT BDO production business outsourcing is a good choice.

   From the demand side perspective, the next few years, domestic demand for PBT growth around 9%, total consumption by 2015 will reach 40 million tons. Automotive, textile industry, this high-end products of PBT will continue to grow. It is worth mentioning that, on the future of PBT in the application of energy-saving lamps are increasingly being used. Thunis company has successfully developed the production of PBT fiber optic cable casing materials, as China's communications and network technology development, the amount will show a rising trend. Overall, China's revocation of anti-dumping measures on imported PBT PBT indicates that China is gradually moving towards a mature industry, the situation of excessive dependence on imports has gone.
