HYMANTOPBON today with everyone, how to quickly identify the type of plastic approach, following you want to help:
First, the optical method: the main test of transparency material, commonly used transparent materials: ps, pc, pmma, as; translucent materials: pe, random copolymer pp, homo pp, soft pvc, transparent abs, etc. Other materials substantially opaque.
Second, the color identified law: In general, the raw material without additives, if itself contains a double bond, the color was slightly yellow, such as abs, due butadiene copolymer, after the polymerization of the polymer still contains a double bond, Thus will significantly slightly yellow.

Third, the density method: test all kinds of plastic density liquid as the medium, testing its plastic ups and downs in a liquid medium to coarse identify the categories of plastic, such as a piece of plastic on the water, floating in the water can be concluded that the raw material is not pvc (due pvc density> 1).
Fourth, the combustion method: the main test of the flame color and smell and smoke emitted during combustion, in general, polyolefin materials are mostly blue flame or light blue, and light relatively mild odor, smoke was white, while Most likely after with burning black smoke, smell strong. In addition, as pe, pp burning a drop phenomenon, and no drops pvc and other fuel, but there are self-extinguishing phenomenon.
Most other identification method is necessary to use a variety of instruments, such as infrared spectroscopy, mass spectrometry, nuclear magnetic resonance, differential scanning calorimetry, thermal analysis, benzene or chlorine feedstock.
