Automotive plastic features:
There are a lot of previous car macromolecular materials without the advantages of traditional materials. Mainly manifested in the appearance of the light weight, good decorative effect, have a variety of practical application function, has the good physical and chemical properties, easy processing and forming, saving energy, sustainable utilization and so on various aspects. The main characteristic of automobile polymer materials as follows. Light weight car polymer materials is one of the most prominent advantages of lightweight high strength characteristics. Due to the average proportion of all kinds of plastic is generally 15-20% of ordinary steel, is lighter than general timber. This feature is especially have prominent advantages for large luxury cars, can lose a lot of weight. Good processing performance Polymer auto material has the very good processing performance. Due to the plasticity of polymer auto materials and other materials with good compatibility between the combination of performance, can use different material components, with the aid of all kinds of modern processing machinery, through extrusion, injection molding, pressing, molding, blow molding method such as processed into a variety of different shapes, different performance, different color, different function of auto polymer materials, such as, crowded into pipes, profiles, plate, directly injected into all sorts of modelling of products, rolling processing into film, etc., can also be made into various color according to need, interlayer, hollow, put the variety of products, such as insert can also according to the requirements for secondary processing, such as mechanical products sample cutting, punching, cutting, welding, can also be hot, cold saw, composite, etc. Good comprehensive physical and chemical properties of the polymer another advantage is the automotive materials has a variety of functions, can be used for special occasions. Most of the polymer materials not only have the plasticity, there are many excellent physical and chemical properties. Plastic has good insulation properties, excellent anti-corrosion properties, aging resistance, good wear resistance and washing resistance, good waterproof performance and mechanical performance, good adhesive bond performance, be processed into a variety of processed into various demands a variety of automotive exteriors of performance and functionality. Excellent decorative effect Auto polymer materials is the most prominent advantage adornment effect is good. It can be processed into products with complex shape and a variety of colors, sometimes also need to print, film, embossed, stratified, colored, processed into very lifelike image, decorative pattern and design, can imitate the natural texture of wood, metal, animal skins, can also be hot stamping, surface film, silver plated, Mosaic, etc. A further advantage of energy saving and environmental protection, auto polymer materials is to save energy and promote environmental protection. Because the alternative to a large number of natural material, can save a lot of resources accordingly, stone resources, protection of forests and does not destroy the ecological environment, more is the social value of energy saving and environmental protection significance. At the same time, because of plastic processing and molding of convenience, energy is far less than needed to make polymer auto processing the same function of natural material, such as steel, animal skins, etc., can save a lot of artificial and energy. Most automobile material with the plastic is thermoplastic, the waste material can be easily recycled and remanufacturing directly, make cars polymer materials on a path to sustainable processing of cleaner production, has the extremely positive environmental significance. Polymer the characteristics of material and there are many, there are also some worse than traditional materials, main shortcoming in its rigidity, heat resistance and combustibility, aging resistance, surface characterization of resistance and freeze resistance, etc. # 1, poor rigidity, high polymer materials have good plasticity, but it's poor rigidity, have larger bearing capacity so it can not be used for local or as the main load-bearing structure, otherwise it will damage such as instability caused by rigidity is not enough; In addition, its ability to resist deformation is better than the traditional materials of natural materials processing.
