During the final stage of leather manufacturing—the finishing process— micro-wax is added to topcoat finishing agents (such as glazes and fixatives). Its primary purpose is to impart a premium feel and practical physical properties to the leather surface. Primary Functions: Hand Feel Improvement (Most Critical Function) Silky Smoothness: Micro-wax particles form an ultra-thin, smooth wax film on the leather surface, significantly reducing friction coefficients to create an exceptionally smooth and refined tactile sensation. Waxy Feel: Delivers a premium, waxed-like fullness and nourished hand feel. Flaw Concealment: Micro-wax particles can slightly fill minor scratches or imperfections on the leather surface, making the grain appear more uniform and flawless. Enhanced Physical Properties Scratch Resistance & Abrasion Resistance: Wax particles form a protective layer on the surface that effectively disperses and cushions external scratching forces, preventing permanent marks on the leather surface and improving durability. Anti-Sticking: Prevents treated leather pieces from sticking together due to temperature and pressure when stacked or rolled. Dulling Effect: Wax particles cause diffuse light reflection, reducing the coating's gloss level. By selecting different types and quantities of micro- wax, the leather's sheen can be precisely controlled from semi-matte to fully matte.

During PVC processing (such as extrusion, calendering, and injection molding), the molten PVC material becomes highly viscous due to heat and mechanical shear forces, readily adhering to the metal surfaces of processing equipment (such as screws, barrels, and molds). This leads to increased energy consumption, reduced production efficiency, rough product surfaces, and even decomposition. As an external lubricant, Fischer-Tropsch wax functions through the following mechanisms: Migration and spreading: During PVC plasticization, Fischer-Tropsch wax migrates from the PVC mixture interior to the melt surface. Formation of a barrier layer: A thin, uniform lubricating film forms between the melt surface and the metal surfaces of processing equipment. Reduced Adhesion and Friction: This lubricating film effectively lowers friction and adhesion between the PVC melt and metal equipment, achieving lubrication. Fischer-Tropsch wax is widely used in various rigid and flexible PVC products: Rigid PVC: This is the primary application area for Fischer-Tropsch wax. Window and Door Profiles: Provides excellent surface finish, facilitates extrusion, and reduces energy consumption. Pipes and fittings: Ensures stable extrusion and smooth inner/outer walls. Sheets and films: Such as transparent PVC sheets and advertising boards, maintaining lubrication without compromising transparency. Injection-molded products: Excellent demolding performance. Flexible PVC: Used as a lubricant and surface modifier in wire and cable compounds, artificial leather, flooring, etc.
