Micronized wax serves as a crucial processing aid and performance modifier in PVC processing, primarily functioning as an external lubricant and surface modifier.
Exceptional external lubrication properties:
Reduces friction: Forms a lubricating film between the PVC melt and the metal surfaces of processing equipment, effectively lowering frictional resistance.
Prevents adhesion: Inhibits melt adhesion to screws and moulds, ensuring continuous and stable production.
Reduces energy consumption: Minimises mechanical shear and friction-induced heat generation, lowering main drive current and conserving energy.
Enhanced surface properties of finished products:
Improved surface finish: Produces smoother, glossier surfaces with superior tactile quality.
Scratch resistance and anti-adhesion: Forms a wax film on product surfaces, enhancing scratch resistance and preventing adhesion during stacking or winding.
Enhanced slip properties: Significantly reduces surface friction coefficients for soft products like films and sheets, improving slip characteristics.
