Modified and alloyed plastics, the choice of their materials is very particular. The first consideration is whether the material is crystalline or amorphous. If it is of the same type, it is more convenient; if it is not the same type, then some technical difficulties will increase, and the cost will increase. In general, what kind of technology is to be determined according to needs. Like PC, its biggest drawback is cracking, but this shortcoming can be overcome by PE modification. The specific gravity of PE is relatively light, so PE will be wrapped in the outer layer of PC after modification, so it is not easy to contact with sunlight and other external factors. This improves the performance of the PC, making it less prone to cracking. In general, each type of plastic has a certain role, such as the purpose of the combination of PC and aBS, in order to enhance the toughness, increase the activity of injection molding, and not be affected by the degree of humidity. So a lot of PC alloys are used, especially in the field of recycled plastics.
