OPE (Oxidized Polythethylene Wax)

• Act as the lubricant, cost-saving agent and release agent in the course of extruding, calendering, injecting, blowing molding of PE, PP and other plastic.
• Act as the dispersant for masterbatches, pigment, carbon black, additive for parent material, filling parent material and other pigments.
• Applied in the field of hot melt road marking material.
• Act as the additive for shoeshine, floor wax, car wax, polishing wax, chinaware, pill wax, paint, coating, cable, carbon paper, wax paper, textile softening agent etc.
• The additive for rubber process and car anti-rust agent etc.

A method of preparation of oxidized polyethylene waxes, which have many applications such as in plastics, rubber, leather, paper, inks and textile, etc. was developed. The experiments of polyethylene waxes oxidization were carried out in a pilot plant. The reactor was a 0.27 m diameter and 3 m high column reactor with a conical distribution plate. The experimental results showed that the optimal conditions for preparation of the Oxidized Polyethylene Waxes were: catalyst KMnO4, reaction temperature 141—148°C, reaction time 3-7 h, air velocity 4—8 m/s. The oxidized polyethylene waxes with acid number of above 30 mgKOH/g could be obtained with this method.

Oxidized polyethylene waxes are used as lubricants in the processing of plastics such as polyvinylchloride to prevent the plastic from sticking to the hot surfaces in the machinery, which saves energy and enhances the material properties of products such as PVC pipes and profiles.

Oxidized polyethylene waxes can also be emulsified in water. Wax emulsions are applied as finishes to textiles in order to obtain a smoother surface in order to make them easier to sew and to make them more resistant to linting and pilling. Polyethylene waxes are used in polishes applied to shoes, furniture, floors and car bodywork and wax emulsions to protect the surface, to provide gloss or to enhance safety by increasing the slip resistance. Addition of wax emulsions to the coating of glossy magazines protects the surface against ink rub-off. A thin layer of wax can also be applied to the skin of citrus fruit to prevent it from drying out and becoming bruised.
