Application analysis of different grades of ABS plastics in the automotive field

ABS plastics can be divided into ultra-high impact type, high impact type, medium impact type, etc. according to their impact strength. According to their molding processing methods, they can be divided into injection, extrusion, calendering, vacuum, blow molding and other grades, depending on their use and The performance characteristics can be further subdivided into 10 varieties including general-purpose, heat-resistant, electroplating, flame-retardant, transparent, extruded, and pipe. The general-purpose injection-grade ABS plastic has the largest market capacity. The car dashboard is an important function and decoration part of the car. If it is made of steel plate, it is not only costly, but also needs more than 10 processes such as cutting, stamping, drilling and painting, and is made of ABS plastic. It can be molded in one injection or blow molding.
1. Low odor ABS plastic
Automotive interiors pursue low VOC performance and improve air quality inside the car. Small molecular organic volatiles in plastics easily migrate to the surface of plastic products and volatilize into the air of the car, causing bodily harm to the occupants.
By selecting a suitable substrate, suitable modification methods and processing techniques, ABS materials that meet the requirements of automobile manufacturers can be obtained.
Low-odor ABS materials are mainly used for the production of door panels, instrument panel trims, glove boxes, central control panels, air conditioning vents and other interior components, especially air conditioning vents that require higher temperatures and conduct air.
2, heat-resistant ABS
For some parts that need to withstand higher temperatures, the heat resistance of ABS needs to be improved. One common method for improving the heat resistance of ABS is to blend ABS with PC to form an ABS/PC alloy. Heat-resistant ABS is commonly used to manufacture heat-resistant parts such as air conditioning vents and heat-radiating grilles. For the heat-dissipating grille, heat resistance can be prevented, and the deformation of the component can be prevented, thereby preventing the plating layer from falling off due to deformation. It is also manufactured by ABS or ASA. The door panel is also made of PC/ABS alloy due to its large area and the need for impact resistance. The fenders of high-end cars are also made of ABS/PC alloy.
3. Extinction ABS
Strong light reflections in the car's cab can cause discomfort and fatigue to the driver and affect the driver's vision during the night. Therefore, extinction ABS has a wide range of applications in automotive cab components. Since ABS is a high-gloss Engineering Plastic, the resin grade with low relative gloss and wide molecular weight distribution is selected during the modification process. And use a sheet or needle-like, large particle size filler. This can improve the surface roughness of the product, so that the light is scattered to achieve the matting effect.
4, electroplating grade ABS
Although ABS has a good aesthetic effect, in order to pursue a better aesthetic effect, it is often necessary to perform surface decoration treatment such as electroplating and painting on ABS.
The electroplated grade ABS is modified by adding a certain amount of rubber to increase the polarity of the material. Electroplating grade ABS is mainly used on heat sinks, decorative parts and other components. Because of its double bond, weathering ABS is prone to degradation under the action of sunlight and hot oxygen, which causes powdering, discoloration and loss of some mechanical properties. Therefore, weatherproof ABS is generally used for ABS for exterior parts.
One of the difficulties in plasticizing automobiles is the plasticization of the outer panels of the body. The outer panels of the body include front and rear fenders, partitions and panels, etc., which have the largest amount of material and require materials with impact resistance, heat resistance and rigidity. Alloys of ABS resin and engineering plastics have these properties and can be used as exterior body materials. Automotive interior parts play an important role in the comfort and safety of the car. Most of the modern automotive interior panels are integrally formed and have a luxurious appearance. ABS resin is generally used.

UPE plastic,full name UHMWPE (ultra high molecular weight polyethylene) is a kind of thermoplastic engineering plastic with excellent properties of linear structure, with a molecular weight of more than 1.5 million.mainly have  ESD UPE SHEET,CONDUCTIVE UPE.

Small density, good wear resistance, self - lubricity, impact resistance, corrosion resistance and so on.

 

Advantages:

1. Average molecular weight about 5,000,000 to 9,000,000;

2.The best abrasive assistance of all plastics , which 4 times higher than that of nylon 66 or teflon and 6 times higher than that of carbon steel;

3.Extremely high impact stength ,which is twice as high as PC ,5 times as high as ABS,it also retaines high toughness at liquid nitrogen temperature (-196'C);

4.Low friction coefficient ,lubricity is equal to that of Teflon ;

5.The best impact energy absorption value of all plastics ,with very good sound reduction effect ;

6.High chemical stability ,capable of resisting various types of corrosion and organic media within certain temperature and concentration range;

7.Strong adhensive resistance which is only second to Teflon;

8.UHMW-PE Plastic is safe , healthful and non-toxic and be can used in contact with food and drugs ;

9.Low density than any other thermoplastic ;

10.Excellent electrical insulation and static resistance ,good resistance to high energy radiation;

11.Moderate mechanical strength,stiffness and creep-resistant property'

12.Outstanding machining property ,very low water absorption .


 

 

Deficiencies:

Compared with other engineering plastics, UHMW-PE Plastic is resistant to heat resistance, stiffness and hardness, but can be improved by means of "filling" and "crosslinking".

From the point ofheat resistance, the melting point of UHMW-PE Plastic is approximately the same (136 ℃) and ordinary polyethylene, but because of its big molecular weight, melt viscosity high, so the processing difficulty is big.
