Engineering plastics can be divided into five categories (polycarbonate, polyoxymethylene, polyamide, thermoplastic polyester, modified polyphenyl ether), and polycarbonate in engineering plastic type, a "stand out", because it not only has good pervious to light quality, impact resistance, resistance to ultraviolet radiation, and stability and good processing performance, but serious supply capacity in our country, to a large number of imported each year, less than 20% self-sufficiency.
At 1 a.m. on September 11th, apple's new conference officially released in the autumn Iphone5S and 5 c, including Iphone5C first use polycarbonate material, and provides a variety of colors to choose from. Apple's first use polycarbonate material, marked the high-end further expansion of engineering plastics in the fields of electronic purposes.
We believe that the high-end engineering plastics vast development space, in addition to the electronic, in the car and expand health also have larger space, and will and automobile lightweight, the new concept of the medical equipment. Therefore, to introduce the theme of the technology foresight in current development situation of the engineering plastics, winner of the recent high-level engineering plastics in the latest development of the automotive, medical and other fields.
Building materials industry
Polycarbonate sheets with good pervious to light quality, impact resistance, resistance to ultraviolet radiation and its products of dimensional stability and good processing performance, making them than traditional construction use inorganic glass has obvious technical performance advantage. China has a polycarbonate hollow board production line more than 20, building materials in need around 70000 t polycarbonate, by the year 2005 to 140000 t.
Automobile industry
High performance polyamide resin will further alternative metals such as: energy conservation and emissions reduction is one of the development direction of automobile industry, compared with the traditional metal materials, a new modified plastics can reduce 30-40% weight of the car, the fuel economy at the same time also can reduce carbon dioxide emissions. Chery company in the near future to choose dupont performance polymers unit for the automotive plastic providers, high performance polyamide resin, vinyl acrylic elastomer composite material in the air inlet, such as cylinder lid, ventilation pipe applied in auto parts, such as plastic strength increase will gradually substitute of metal.
The medical field
Stronger polyurethane elastomer excellent biocompatibility, mechanical properties, the body's tissues and blood of medical devices implanted elastic material has a considerable challenge, these materials must be able to long-term exposure to bad under the body temperature of water environment, and maximum reduce the complications of patients, reduce blood clotting, rejection, tissue inflammation and toxic chemicals into the body. Polyurethane elastomer related performance, some models such as Pellethane aromatic polyether type 80 a - 75 - d is applied to the iv, iv drip bucket, needle extension tube, cases of incision, Tecoflex aliphatic polyether type 72 a - 83 - d is applied to central venous catheter, catheters, nasogastric tube, gastric endoscopy catheter, cardiac assist device, long-term huge space for development.
