Modified plastics have three main advantages
First, it is relatively light, which is relative to metals and plexiglass. The reason for lightness is not because it is a polymer compound, but because they are organic compounds, that is, lighter than carbon, hydrogen, oxygen, nitrogen, etc. The composition of the elements.
Second, plastics are easy to process. The plastic has plasticity, that is, it deforms after heating or pressurization, and maintains the original shape after cooling or pressure disappears. It can be processed into products of respective shapes by extrusion, injection or the like.
Third, the plastic will not rot or rust. However, this property also poses a serious problem for human beings: due to the fact that plastics are not easily rotted, a large amount of plastic waste cannot be absorbed and decomposed by nature, resulting in a certain degree of environmental pollution.
