The development direction and the factors of the plastic1

The development direction of plastic can be summarized as two aspects. One is to improve the performance, that is, in a variety of methods to existing varieties were modified, make its comprehensive performance was improved; Second, development capabilities, the development which has the function of the physics such as light, electricity, magnetic polymer materials, make the plastic to the photoelectric effect, thermoelectric effect and piezoelectric effect, some plastic itself is pure resin, plastic identification can use infrared spectrometer, paramagnetic resonance spectroscopy and X-ray, etc. The scientific method, but also can use the relatively simple and easy method for identification.
