The main characteristics of plastic

Time:2021-01-09 Click Quantity:
Most plastics are light, chemically stable, and will not rust.
Good impact resistance;
It has good transparency and wear resistance.
Good insulation, low thermal conductivity;
It is generally molded and coloured, and the processing cost is low.
Most plastics have poor heat resistance, large thermal expansion rate and easy combustion.
The dimensional stability is poor and easy to deform.
Most plastics are low temperature resistant, brittle and easy to age at low temperature.
Some plastics are easy to dissolve in the solvent.
Plastics can be classified into two types: thermosetting and thermoplasticity. The former cannot be rebuilt and the latter can be reproduced. The physical extension rate of thermal plasticity is larger than that of 50%~500%. Under different elongation rates, force does not change linearly. For plastics R & D institutions or enterprises, there are plastic tensile testing machines for European standard instruments.
The different properties of plastics decide its application in industry. With the progress of technology, the modification of plastics has never stopped. It is hoped that in the near future, plastics will be more widely applied after modification, and even replace materials such as iron and steel, and will no longer pollute the environment.
