1, From the appearance, the surface of the silicone wire is foggy, with a not very bright color and a slight gray on the surface, which can still stick to the hand when touched; The surface of PTFE wire has a good luster, and it is very smooth when touched by hand.
2, In terms of outer diameter, as for the outer diameter of silicone wire of the same specification, Silicone wire is much thicker, while PTFE wire has a smaller diameter. The electrical properties of PTFE wire are better than silicone cable, and it can withstand the same voltage, so its thickness is much smaller.
3, From a soft and hard perspective, silicone wire is like rubber tape, very elastic, and will bounce back when bent by hand; Teflon wire is relatively hard, and it will deform when bent by hand.
4, If you use your hand to scratch the surface of the PTFE wire again, there will usually be a mark that is difficult to break through, so its tensile strength is better than that of silicone wire. However, silicone wire can break its skin with a gentle scratch. Although their elongation is good, the tensile strength of silicone wire is not very good.
