Identification of different processed plastics for electronic wire harnesses

Basically every electronic harness will be processed plastic, different applications designed to use different types of plastic, if you want to identify these electronic harnesses in the end is the use of which type of plastic, with the naked eye alone is very to identify out, the following is mainly for you to elaborate on the electronic harnesses of the different processing of plastics to identify the way.-First, PU plastic PU plastic identification method is PU with magnetic, very good elasticity, expansion and accompanied by drops when burning. Second, TPE / PO (thermoplastic elastomer) plastic TPE / PO (thermoplastic elastomer) plastic identification method is burning smoke is small, non-toxic, will not produce pungent odor, belong to the low-smoke halogen-free materials. Third, XLPE / XL-PVC plastic XLPE / XL-PVC plastic identification method is to cut a section of the wire to remove the conductor, with the fire from the center of the beginning of the burn, and then pull the line with force to break the section is very rounded. Fourth, PE (polyethylene) plastic PE (polyethylene) plastic identification method is PE surface is relatively smooth, burning flame on the yellow and blue, there are drops, burning will produce a slight candle flavor. Fifth, PVC (polyvinyl chloride) plastic PVC (polyvinyl chloride) plastic identification method is PVC burning yellow flame, black smoke, the bottom edge of the flame is green, and there is an unpleasant odor. Six, PP (polypropylene) plastic PP (polypropylene) plastic identification method is the appearance of PP is a white candle-like solid, more transparent, the surface is smoother, harder with PE; combustion flame on the yellow under the blue, there is a drop, there is a stench when burning, before a slight candle flavor.
