How is the surface lubrication of the Automotive Wiring Harness Protection Sleeve achieved?

For Automotive Wiring Harness Protection Sleeve products to be sold well, not only must they be of good quality, but they must also feel good. Generally, there are two situations when the surface of Automotive Wiring Harness Protection Sleeve products will feel lubricated. One is that a layer of hand oil is applied on it; the other is that lubricant is added to the formula. The following Automotive Wiring Harness Protection Sleeve manufacturers will analyze the differences between these two types.

The surface of the Automotive Wiring Harness Protection Sleeve product is spray-coated, and it feels very good. The main material is EPDM rubber. Is it added with dioctyl ester or the like so that it can be sprayed out to provide internal lubrication? If it is a filling system such as talc powder, it will never produce this effect.
After I came into contact with the spraying of Braided Sleeve, I learned that the effect of adding any kind of material is not as good as spraying, and it also increases the aging performance, but it is difficult to spray small or heterosexual items. Soak it in water-soluble silicone oil and dry it to get the effect you want. Molded products can be added with silicone lubricant and sprayed on the surface to have such an effect; extruded products can be sprayed on the surface. The effect is better.
I have encountered this problem before, that is, the customer's Braided Sleeve product looks very smooth and shiny, and feels like a layer of oil to the touch. The performance of the products produced by myself is up to par, but the surface looks dry and feels raw to the touch.
Adding an internal lubricating flow aid to the formula will spray a thin layer of frost on the surface of the product, making it look bright and feel smooth. It is also conducive to subsequent assembly of the product. I have tried spraying on the surface. The sprayed layer wears away easily after friction or contact. What is added to the formula and migrates to the surface of the product will be replenished and sprayed out after grinding to maintain the oily and shiny effect on the surface of the product.
