Zhi-guo qian, chief engineer of Beijing institute of chemical industry research and development center, with plastic instead of metal parts, can not only reduce vehicle weight, reduce fuel consumption and emissions, can also increase the power, comfort and safety of cars, so it is widely used in automotive power and chassis systems, both inside and outside decoration, automobile electronic components.

 

We have learned, polyamide (PA) material is mainly used in power, chassis components and parts, accounts for about 20% of the whole vehicle plastic; Polycarbonate, polyoxymethylene and modified polyphenyl ether and thermoplastic polyester material is mainly used in electrical and electronic components and parts, accounts for about 15% of the whole vehicle plastic around. Modified polyphenyl ether (PP) and abs engineering plastics and its alloy material is mainly used in internal and external decoration parts, with the increase model class, engineering plastics application increase, rising rates of abs and its alloy application. She also introduced the application of engineering plastics in the car some advantages, such as the long glass fiber reinforced composite materials instead of metal dressing, can reduce the external objects (including pedestrians) on the impact of the body; Plastic products also has the ability of absorption and attenuation of vibration and noise, and can improve the ride comfort; Made from plastic body covering parts is very suitable in the polluted areas use; Steel parts if paint damage or advanced anti-corrosion doing well is easy to rust corrosion of metal, but plastic corrosion resistance is strong. Plastic to acid, alkali, salt and other corrosion resistance than steel plate. In addition, use plastic instead of metal parts, its cost can be reduced by 30% ~ 40%.

 

Haze, energy conservation and emissions reduction, and more stringent fuel economy regulations, domestic automakers have spare no effort to develop automotive lightweighting technologies. As is known to all, auto lightweight optimization design mainly embodied in the automobile, the alloy material and non-metallic materials applications, it in turn to a car light weight loss by 10% ~ 15%, 30% ~ 40%, 40% ~ 55%. Ryan told reporters, engineering plastic and other non-metallic materials "lose weight" effect is obvious, main effect is to make the car on its use in automotive lightweighting. At present, more and more auto parts started using engineering plastics instead of metal parts.
