pcABs alloy plastic has outstanding impact toughness and creep resistance, good heat resistance, and good cold resistance. Shrinkage is 0.5-0.7%, and suitable wall thickness is 2-3.5mm. Adding PC plastic to glass fiber can improve its shrinkage, mechanical strength and temperature resistance. The steel will increase in long-term use at about 100 ° C. Annealing can be used to improve internal stress. The main composite pcABs are alloy plastics. What are the applications of pcABs alloy plastics in the automotive field?
pcABs alloy plastics are blended materials of PC and ABS. They are usually supplied in the shape of pellets after blending. If the two materials are simply mixed and then directly injected, the effect is very poor, and delamination will occur.
The advantages of PC plastics are rigid and tough, but the disadvantages are stress cracking and high viscosity. ABS plastic has the advantage of good fluidity but low surface hardness. pcABs alloy plastics have higher surface hardness, higher rigidity and toughness, and higher resistance to stress cracking. Its mechanical properties are somewhere in between.
In the automotive field, it is mainly used in the manufacture of lampshades, left and right wheel cover shields, left and right wind frame covers, rear bumper cushions, etc. The application of pcABs alloy plastics in the automotive field is the instrument bezel body and the middle wind frame cover.
