New energy automotive materials new hotspots - PBT.

Currently, the world's leading PBT resin producers include basf, dupont, GE, desman, Saudi basic industries and other companies. In 2016, the world of PBT resin production capacity of 1.95 million tons/year, mainly concentrated in the United States, Western Europe and southeast Asia (China, Japan, South Korea and Malaysia), the three countries region capacity respectively accounted for 8%, 19% and 73% of total capacity. With demand change regional migration and technology, 2017, major changes have taken place in the world PBT production pattern, the main domestic from dependence on imports for the production of PBT, production capacity of nearly 1 million tons, account for around 50% of the world.

At the same time, with the rapid development of domestic new energy automotive industry as well as the urgent demand for high performance and special performance materials, domestic and international giant launch high-performance PBT materials businesses, the layout of new energy automobile market. PBT, the main applications of new energy vehicles are battery components, connectors, and charging pile, such as high temperature resistance, resistance to hydrolysis, high tracking index and halogen-free flame retardant, weather resistance is the key development direction.
Previously, basf said because of the growing global demand for engineering plastics, announced its expansion in Germany to val, Hyde composite factory work has been completed, and began formal operation, the expansion will PA and PBT, the global composite capacity up to 700000 tons.
In May 2017, dupont (DPM) for the first time new high performance materials division series Crastin ® glass fiber reinforced poly (butyl glycol terephthalate (PBT) product specifications. The relative leakage of this series of products (CTI) is up to 600V, which is a customized product for plug-in electric vehicle (xEV) commonly used high voltage connectors. It also has excellent mobility and excellent hydrolysis resistance. These features can be used to produce smaller, thinner connectors and other electrical insulation components, and can also be used in plug-in electric vehicles for custom high voltage connectors.
In May 2017, blonde hair is used to develop flame retardant PA and PBT materials for charging piles and supporting products.
In May 2017, wuxi thriving new material technology co., LTD., is planning to build 50000 ㎡ workshop, annual output of 80000 tons of PBT fiber on new production line, the expansion project is located in yixing city.
In May 2017, shun phlogistic new material of a kind of "850 ℃ hot wire not burning flame retardant reinforced PBT plastics and its preparation method" has obtained national invention patent. New PBT material adding flame retardants is multivariate of flame retardant compound and into, can significantly improve the flame retardant efficiency of PBT, increase the temperature of the PBT, the glow wire at the same time, ensure that the mechanical properties of PBT, plastic can satisfy the use requirement. PBT resin is mixed with flame retardant after special treatment, and the specific surface area of PBT resin and flame retardant is improved so that it can be fully mixed. At the same time, the flame retardant has been pretreated, and the activation energy of various flame retardants has been improved to make the flame retardant more efficient.

高灼熱絲材料制品

Launched in May 2017, guangdong harmony from primer lamp material PBT, avoid primer PBT material advantage is good heat resistance, low cost, low forming easily, sending out, free coat, good liquidity, high yield, excellent and replication of the mould. The material of the molding ring can achieve a very bright surface effect without the direct vacuum plating of aluminum.

In July 2017, bluestar's recent successful launch of nantong stars glow wire light-off temperature (GWIT) 775 ℃ + thin-wall high flow type modified PBT engineering plastics Starester ® 203 g30, the products are mainly applied to relay, capacitor, electric switch, terminal row in various fields, such as more than has been industry benchmarking customer successfully applied in its terminal products.
In July 2017, lansheng and rahuk group developed a new composite alloy material called PocanAF4130. It is a PBT/ASA alloy with 30% fiberglass and a halogen flame retardant.

In August 2017, French car supplies valeo developed a top of the steering column module, the module of the shell and pull rod by basf registered trademark of engineering plastics (Ultramid polyamide and Ultradur terephthalic acid butyl ester). The new module is about 20 percent lighter than before, and basf's material has a high finish, high uv resistance and excellent mechanical properties. The BMW group, which drives the BMW 3-7 series, is the pillar module.

 In August 2017, the jilin provincial people's government network released, and it is expected that songyuan city will build an annual output of 50,000 tons of PBT projects. The total investment of the project is RMB 30,000 yuan, of which the construction investment is 250,000 yuan.
In August 2017, xinjiang lanshan tunhe chemical co., LTD. Million tons bio-new materials science and technology industrial park project started in changji hi-tech zone. It is understood that the project including the annual output of 60000 tons of PBSA full biodegradable resin, 60000 tons 200000 tons of PBT resin, PET resin 3 project, the PBT project to meet the rapid growth of automotive engineering plastic, electronic appliances, textile and other fields.
In November 2017, the Dutch royal DSM group, developed a new type of resistance to hydrolysis PBT for Arnite ® thermoplastic polyester series add new products. The new material will provide a cost-effective solution for high temperature and humidity applications (including automotive connectors, control equipment and sensors).

The new type of resistance to hydrolysis product can meet the market demand for resistance to high temperature and high humidity material growing, for it is not need to use such as DSM Stanyl ® PA46 and ForTii ® PA4T etc. The application of high performance, high temperature resistant polyamide materials.
In addition, the three - breed, nanjing polylong and other enterprises also launched the corresponding high performance PBT connector usage plan.
From the layout of the major companies, we can see some signs of the new energy automobile industry, such as PA6 and PA66, which cannot meet the requirements of specific applications such as the new energy automobile industry and related supporting facilities. Vendors at all levels see high-performance PBT as transition materials from these materials to more expensive special materials solutions. At the same time, with the sound of the new energy industry chain around the world, PBT may become a new hot spot for vehicle materials.
