the recession caused by financial crisis and the situation is completely different hot automobile market anomaly, the Government encourages the consumption of good policy car and car to the countryside and other activities is has fueled results. As the automotive industry in recent years, the rapid demand for plastic, plastic industry and the automotive industry in China has become “a prospering harmed” trend. Plastics industry turning to plastic modification, use of lighter, stronger, better auto parts to ease high oil prices, auto industry slump.
Car HC plastic mesh News: Modified plastic is in polymer (resin) addition of inorganic or organic small molecules, through physical or chemical action, in order to give a performance (mechanical processing performance) or to a performance improvement. Such as toughness, enhanced by plastic, flame retardant, etc., made through modification of plastics has become a rare feature, and this one should be in the car and Home Appliances Field application and development of modified plastic potential of the most significant.
Modified plastics is the most important automotive lightweight materials, parts and components not only reduces the quality of about 40%, but also can reduce procurement costs about 40%, so in recent years, a rapid increase in the amount of cars. Automotive interiors are now basically plastic-based, “Plastic in” development is driving a car with modified plastics in automotive applications continue toward a broader field of innovation.
Then present the main applications in the automotive plastics modified what, and in automotive parts application where is it? Are interested Jiugen Xiaobian together collecting about it!
I. Nylon Nylon used car engines and engine parts around the main variety is GFPA6, GF PA66 Enhance the flame-retardant PA6 and other products. (1) automobile engine peripheral parts of the application: As the main components around the engine heat and vibration components, the components used in the majority of glass fiber reinforced nylon material. This is because the nylon has good overall performance, with the modified glass fiber nylon, the main performance is greatly improved, such as strength, precision products, such as dimensional stability are greatly improved. In addition, the nylon variety, easier to recycle and reuse, and low costs, these factors contribute to the peripheral parts of nylon into the engine ideal material. Intake manifold is modified nylon in a typical vehicle application, BMW of Germany in 1990, the first glass fiber reinforced nylon as raw materials will be manufactured in the intake manifold used in six-cylinder engine; after Ford and DuPont company Cooperation Together with glass fiber reinforced PA66-made intake manifold used in V6 engine, after the world’s major car companies have followed suit, modified nylon intake manifold is widely used.
(2) In the application of automotive engine parts. Engine cover engine decorative cover, cylinder head covers and other components are generally the preferred material of modified nylon, and metal materials, compared to the cylinder head covered 50% of case quality and reduce cost by 30%. In addition to engine parts, the car’s other components can also be used by forces reinforced nylon, such as oil filters, wiper, radiator grille and so on. October 2009, DuPont nylon resins for the first time applied to Denso’s new automotive radiator end tanks. The project is DuPont can Recycled plastic Key parts in the engine the first time around, innovative applications, material properties sufficient heat under the hood and the stringent requirements of chemical corrosion.
