Basically, each electronic wire harness is processed with plastic. The types of plastics used in design are different in different application environments. If you want to identify which type of plastic is used in these electronic wire harnesses, it is very obvious to the naked eye. Mainly for everyone to explain the identification of different processing plastics for electronic wire harnesses.
First, PU plastic
The identification method of PU plastic is that the PU belt is magnetic, the elasticity is very good, and it expands with burning and dripping. Second, TPE / PO (thermoplastic elastomer) plastic
TPE/PO (thermoplastic elastomer) plastics are identified by a small smoke, no toxic gas, no pungent odor, and a low-smoke, halogen-free material.
Third, XLPE / XL-PVC plastic
The identification method of XLPE/XL-PVC plastic is to cut a piece of wire to remove the conductor, start the fire with the fire from the middle, and then pull the wire hard, the section is very round.
Fourth, PE (polyethylene) plastic
The identification method of PE (polyethylene) plastic is that the surface of PE is relatively smooth, and the flame is yellow and blue when burning, and there is dripping, which will produce a slight candle smell when burned.
5. PVC (polyvinyl chloride) plastic
The identification method of PVC (polyvinyl chloride) plastic is that the PVC has a yellow flame when burning, black smoke, the flame at the bottom is green, and there is an unpleasant smell.
Sixth, PP (polypropylene) plastic
The identification method of PP (polypropylene) plastic is that the appearance of PP is white candle-like solid, transparent, the surface is relatively smooth, and it is harder than PE; when burning, the flame is yellow and blue, there is dripping, and there is a smell when burning. After that, there was a slight candle smell.
The identification of different processing plastics for electronic harnesses is introduced here.
