Why LFT plastic alternative metal favored by car manufacturers do?

1.Excellent performance In addition to common engineering materials such as PP and ABS, nylon plastics represented by PA6, PA66 and long carbon chain nylon have been increasingly used in automobiles due to their excellent mechanical properties, electrical properties and dimensional stability The more recognized. Especially the higher ambient temperature around the engine, a more corrosive environment, the use of plastic put forward more stringent conditions. The nylon material with excellent temperature resistance, chemical resistance and good mechanical properties, in the car has a very large potential. The application of nylon modified materials in the automotive field is mainly based on structural parts, and is very important to the safety of automobiles. Therefore, the requirements of automotive nylon materials are also stricter. It is an important indicator to measure the technical level of material production enterprises. At present, the automotive industry has become the largest consumer of modified nylon materials market, accounting for about 30% of the total market demand. To BMW328I, for example, the amount of automotive plastic used 162Kg, PA material usage was 21.8Kg, accounting for 13%. Common automotive nylon materials are fiberglass / mineral reinforced mainly PA6 and PA66 for intake manifolds, engine cylinder heads, radiator housings, throttle pedals, heat exchangers, oil pan and rear view Mirror bracket and other components.

2. Spray-free materials - make the car more environmentally friendly In order to achieve a more beautiful appearance of interior and exterior trim, many decorative parts have been spray-painted to obtain different effects of the metal texture. However, the spraying process has the disadvantages of complicated processes, pollution of the environment, high production cost and easy stripping of the parts. If the appearance of the parts is directly given in the injection molding process, energy saving and emission reduction can be achieved and the production cost can be reduced . Spray-free material is based on the above-mentioned needs, to solve the shortcomings of traditional plastics, to meet product use features, both decorative and aesthetic role. Compared with the traditional modified plastics, the spray-free material has many advantages such as rich color, good surface gloss, diversified aesthetic needs, more environmental protection, 100% recycling, and low comprehensive cost. In the automotive field, spray-free materials are mainly applied in high gloss and metallic luster. High gloss spray-free materials are mainly PMMA / ASA, PC and ASA, they are mainly used in automotive control panels, grilles, fenders and other components. Metal-luster effect of the spray-free materials mainly PP, ABS, PC / ABS, PMMA, PA-based, can replace the electroplating plastic for car bumpers, pedals, luggage and other parts.

3.LFT Plastics - Lower Automotive Manufacturing Costs LFT plastics are thermoplastic composites based on thermoplastic resins and reinforced with long glass fibers (mainly glass fibers and carbon fibers). They are light weight, high strength and impact resistant Toughness, corrosion resistance, forming process performance, design and repeat recovery, environmental protection and other superior performance. At present, LFT plastic is mainly made of glass fiber. The plastic matrix mainly consists of polypropylene (accounting for more than 80% of the plastic matrix). It is mainly used in the manufacture of automobile semi-structure and structural parts, and can replace light metal and expensive engineering plastic. At present, the long fiberglass PP material has been used by some automobile manufacturers for parts such as car pedals, battery trays, door modules, front-end modules and tailgate, not only replacing the original costly aluminum metal or PA materials , But also to achieve a modular design of parts, to further reduce the car manufacturers manufacturing costs.
