Automotive exterior parts is an important part of the car body, engineering plastics because of excellent workability, excellent performance and, reduce costs, to achieve a number of advantages such as lightweight, is more and more replaced by metal used in automotive parts Manufacturing, a large part of which is used in automotive exterior.
In automotive exterior applications, engineering plastics must not only be able to withstand significant loads, but also have outstanding UV and chemical resistance (eg, detergent) performance while meeting the high demands of appearance.
Automotive exterior parts Commercial products using modified plastics are mainly bumpers, radiator grille, fender, lamp housing, rearview mirror housing, skylight system, wiper, pillar trim, door handle, Body trim, engine cover, trunk lid, back door and hard top and so on.
The plastic materials used include polypropylene, polyethylene, polyurethane, nylon, ABS, polycarbonate and fiber reinforced composites, etc. The proportion of the plastic parts used in passenger cars to the total body weight has reached an average of 8% to 12% , But the proportion applied to exterior parts accounts for only 1% ~ 2% of the total body weight.
The major development directions for plastic automotive exterior technology are component integration and modularity, high surface quality spray-free material technology, and overall composite body panels and all-composite bodywork. The development of new materials and new process technologies is driving the growth of plastics in the bodywork Exterior applications, plastic in the future development of automotive technology will play an increasingly important role.
Polycelon is an early company in the field of automotive plastic.Sercel Long Automotive Division was established in 2004 and officially entered the automotive material market through the confirmation of Nissan China Automotive in 2008. The automotive plastics include: Modified PP, PA6, PA66 , ABS, PA / ABS, PC / ABS, ASA, PC / PBT, PET / PBT, MPPO, widely used in automobile bumpers, dashboards, interior and exterior parts, engine peripherals, air conditioning systems, lights and other components .
In the field of car exterior, Polyester dragon used in the fender material PPO / PA and PPE / PA, used in car handle with PET / PBT, PET / PC, etc., used in the bumper with PP T15, etc. .
