one Plastic characteristic advantage: the proportion of light, good insulation, easy processing, color more, does not rust. Disadvantages: low intensity, easy ageing, with static electricity. 2, 1, what is plastic, plastic basic plasticizing processing, under the condition of heat compression can be cooled to form a fixed shape of polymer. 2, the classification of the plastic ( 1) Thermoplastics, plasticizing melt when heated, cooled the process of solidification, the category of plastics can be repeatedly. ( 2) Thermosetting plastics plasticized melt when heated, cooled solidified into molten melt material, this process can not be repeated a kind of plastic. Three, the classification of the varieties of plastic manufacturing process.
