What is oxidized polyethylene wax?
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.
What is polyethylene wax made of?
Polyethylene Wax, also known as PE Wax, is an ultra low molecular weight polyethylene consisting of ethylene monomer chains. PE wax has a large variety of uses and applications. PE Wax is available from on-purpose production and as a byproduct of polyethylene production.
What is polyethylene wax used for?
Some of the many applications of polyethylene wax are paper-coating, crayons, packaging, ink and leather auxiliaries. Others are food additives and paints.
How do you make polyethylene wax emulsion?
Emulsification: add KOH concentrated solution, emulgator and water to oxidic polyethylene and stir them in high speed under high temperature to make emulsion with required concentration. Ionicity of polyethylene emulsion depend on its emulgator.
What is polypropylene wax?
DESCRIPTION : Waxes are low melting inert products usually snow white in colour. These could be of natural origin e.g. bees wax or synthetics e.g. polypropylene wax etc.
Is polyethylene a paraffin?
Paraffin wax, also known as crystalline wax, is usually a white, colorless and odorless waxy solid. Polyethylene wax, that is, low molecular weight polyethylene, also known as polymer wax. Polyethylene wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings.
What is polyethylene wax emulsion?
Polyethylene emulsion are a family of synthetic waxes used as additives or modifiers in printing inks to improve mar and abrasion resistance, slip, control of rheology, and other properties. In the fluid, the polyethylene wax can control its rheology characteristics.
What is polyethylene emulsion?
polyethylene wax emulsion is a soft finishing agent with special function in textile processing. Its main components are low molecular weight polyethylene (molecular weight of 1000 ~ 3000), which is also known as polyethylene wax. The oxidation-modified polyethylene wax is called oxidized polyethylene wax.
What is the structure of polyethylene?

Does polyethylene dissolve in oil?
Polyethylene wax had good oil solubility. When the temperature was lower than its melting point 10 or 20 degrees centigrade, the oil solubility could reach above 97%. The melting point of polyethylene wax was related to molecular weight.
How do you make emulsion wax?
The method requires the application of waxes with a low melting point and a relatively low viscosity. The wax into water method most often comprises the melting of wax with the addition of one emulsifier and adding the mixture to hot water, containing other emulsifiers and additives with vigorous mixing.
How is oxidized polyethylene wax used in PVC?
Oxidized Polyethylene Wax (OPE) is used as processing auxiliaries for PVC shapes, pipes and plates to increase the surface smoothness of the processed products with an amount of 0.3-0.5%. Oxidized Polyethylene Wax (OPE) can increase the demoulding property effectively and reduce mould-cleaning time significantly in processing plastic products.
How are polyethylene waxes made and how are they made?
Polyethylene waxes are being produced through the highpressure polymerization of ethylene. Highly derived, very stable (temperature, pressure, UV light, chemicals) molecular structures are being produced. Final products made from these are very durable and do not yellow.
What can oxidized high density polyethylene be used for?
Oxidized High Density Polyethylene (HDPE) is a specialty polymer that finds a wide range of applications as an additive in a broad range of industries. The oxidation of HDPE allows formulators to incorporate the beneficial properties of hydrophobic HDPE into aqueous systems.
Can a wax emulsion be applied to polyethylene?
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.
