Which PVC products require the addition of oxidized polyethylene wax?
①PVC profiles, PVC pipes, extruded profiles, PVC buckle plates, and PVC injection fittings: improve the demolding properties of rigid PVC and the plasticization and precipitation resistance of PVC products.
When producing ultra thick PVC pipes, there are higher requirements for plasticization, and oxidized polyethylene wax can effectively improve the plasticization speed of production. When producing PVC injection molded pipe fittings, adding oxidized polyethylene wax can significantly improve the surface glossiness of the fittings. Complex cross-section PVC profiles. Adding oxidized wax can better control plasticization and flowability, and avoid precipitation.
②PVC foam products
Unlike conventional rigid PVC extrusion, the dynamic foaming process has higher requirements for PVC plasticization and melt strength. For example, oxidized polyethylene wax is used as a lubricant in PVC foam shoe soles to improve the fluidity and processing performance of PVC foam shoe soles, effectively reducing the friction coefficient of PVC foam shoe soles, and improving the glossiness and texture of the surface of PVC foam shoe soles.
③PVC transparent products
Like PVC heat shrink film. Due to the incompatibility between non-polar polyethylene wax and PVC, it is impossible to produce highly transparent PVC products. Polarized oxidized polyethylene wax can effectively avoid affecting transparency and improve demolding performance. However, please note to add an appropriate amount.
④PVC decorative film
Higher demolding performance is required during the production process. Oxidized polyethylene wax can effectively improve the demolding effect in the later stage.
⑤PVC edge banding, SPC flooring
PVC high-speed extrusion edge banding requires better metal stripping and precipitation resistance for lubrication formulas. Oxidized polyethylene wax is a very suitable lubricant for later use. For example, PVC flooring with high filling content, such as SPC flooring. Oxidized wax can better improve the plasticization speed under high calcium formula, protect the screw, and extend the screw life.
⑥PVC products with electrical performance requirements
Used as a lubricant for cable insulation materials, it can enhance the diffusion of fillers, increase the extrusion molding rate, increase the mold flow rate, and facilitate demolding. Such as PVC wire and cable materials. Adding oxidized wax can not only improve the surface glossiness, but also effectively enhance the electrical performance. Different applications have different requirements and focuses on oxidized polyethylene wax.
Oxidized polyethylene wax can be regarded as a divine assist in maintaining the lubrication and balance of PVC products, and is indispensable in the PVC product industry.
