What are the advantages of plastic materials for automobiles compared with traditional steel plates?
Since special emphasis is given to "thermoplastic", the surrounding thermoplastic is concerned.
Thermoplastic polymers are linear polymers and thermosetting polymers are mainly polymers of body structure.
Thermoplastic and "thermosetting" difference is that thermoplastic plastic will soften or melt after heating, hardened after cooling, can be repeated. And thermosetting will not, after molding, the temperature is high enough to only decomposition or combustion.
Easy to recycle, heat, soften, or melt, as of metal. For example, recycling of thermosetting plastics usually involves mechanical crushing to destroy the structure;Flexibility is large, brittleness is low, but rigidity, heat resistance and dimensional stability are not good (as determined by structure);Thermosetting is higher rigidity, heat resistance, difficult to deformation, mechanical strength, and can often replace metal as structural materials, such as bumpers and other structures that require force.
