more+Plastics, Modified Materials and Products
Plastics are a type of materials made from synthetic or natural polymers. They can be freely molded into various shapes and finally retain those shapes, or they refer to plastic - formable material products.
l Characteristics
Light in weight, stable in chemical properties, water - resistant, non - corrosive, good toughness (excellent impact resistance), good insulation, low thermal conductivity, relatively good wear resistance, good formability and colorability (beautiful in color), and low processing cost; it can have good transparency and significant physical property variations.
However, most plastics have poor heat resistance, a large coefficient of thermal expansion, are flammable, have poor dimensional stability, are prone to deformation, have poor low - temperature resistance, are prone to aging, and some plastics are soluble in solvents.
Plastics can be classified into two categories: thermosetting (three - dimensional network structure) and thermoplastic (linear structure).
