How to judge whether it is the material of the Automotive Wiring Harness Protection Sleeve

Because it has excellent high temperature resistance and low temperature resistance, good physiological stability, and can withstand repeated harsh and disinfection conditions, has excellent resilience and small permanent deformation, the breakdown voltage is high, ozone resistance, UV resistance, radiation resistance and other characteristics. Therefore, it has been widely used in our life. But until now, there are still many people who have no idea about the protective sleeve of the car wire harness. They don't know what the Cable Sleeve is. Some people think it refers to the common Cable Sleeve baby pacifier, and some people completely use the Cable Sleeve and latex When it is the same thing, what is worrying is that when we need this thing, we don't know how to choose these Automotive Wiring Harness Protection Sleeve.

Automotive Wiring Harness Protection Sleeve have been widely used in our lives, but due to the drive of profit, there are also fake Cable Sleeve on the market. Many unscrupulous manufacturers have produced a lot of fake and shoddy products in order to save costs and maximize profits. Low quality Automotive Wiring Harness Protection Sleeve, shoddy. These car wire harness protectors generally contain certain harmful substances. Compared with the real non-toxic, colorless and odorless Automotive Wiring Harness Protection Sleeve, they will endanger our health. Then these fake and low-quality car wire harness protectors should be How to identify it, let's discuss how to distinguish between true and false Automotive Wiring Harness Protection Sleeve:
1. In terms of characteristics, the Automotive Wiring Harness Protection Sleeve is non-toxic, odorless, colorless, good in texture, and has no harm to the human body. However, it is difficult for counterfeit Automotive Wiring Harness Protection Sleeve to achieve these effects. They are all poisonous and have a pungent smell, and they are also relatively rough.
2. In terms of hand feeling, the toughness and elasticity of the Automotive Wiring Harness Protection Sleeve are very good, it is not easy to be permanently deformed by external force, and the hand feel will be smoother, while the fake Automotive Wiring Harness Protection Sleeve is easy to deform, and because of the fake There is no layer of grease-like substance on the surface of the Automotive Wiring Harness Protection Sleeve. So it will be rough to the touch.
3. Due to the natural adsorption characteristics of the Cable Sleeve, the instant noodles of the Cable Sleeve are easier to stick to fine impurities such as dust and hair.
4. Through the combustion comparison, it can be concluded that the fake silicone rubber products are burning with an open flame, the smoke is black, and there is a stench. White smoke, tasteless. Regardless of the color of the Cable Sleeve, the edge is white after burning, and the burning residue is a powdery object.
5. Test by chemical method: burn the silicone rubber and touch the smoke with a watch glass, collect the white powder, dissolve the powder in a hot solution of 40% strong alkali (60 degrees), take a drop of the solution into a test tube, add two drops of molybdic acid Ammonia, heated slightly, after cooling, add a drop of aniline solution and 3-8 drops of saturated sodium acetate solution, observe the color reaction of the solution, if blue appears, it means there is silicon element, which proves to be silicone rubber.
