Polyethylene wax may not be new to many people. It is also called PE wax or macromolecular wax. As an additive, it can be directly added to PVC processing to increase all aspects of product performance. What is oxidized polyethylene wax? What are its properties and uses? Now let's talk about it in detail.

Oxidized polyethylene wax, also known as OPE wax, is a kind of plastic additive with smooth inside and outside and bright outside. As there are mountains, oxidized polyethylene wax is a mountain higher than polyethylene wax. The difference between oxidized polyethylene wax and polyethylene wax is that oxidized polyethylene wax contains a modified wax product with a polarity gene, which makes the performance of oxidized polyethylene wax, such as durability and polishing, much better than polyethylene wax. In addition, compared with polyethylene wax, the chemical properties of oxidized polyethylene wax are more stable, non-toxic and non corrosive, which makes the application of oxidized polyethylene wax more widespread.

Use of oxidized polyethylene wax

1. Good emulsification performance. Because a large number of oxygen-containing groups are introduced in the oxidation process of oxidized polyethylene wax, which reduces the interfacial tension during emulsification, a stable emulsion of oxidized polyethylene wax can be prepared, and the amount of emulsifier can also be reduced, which is very important for the polish.

2. Good color dispersion. The deeply oxidized wax products contain a large amount of carboxyl groups. The oxidized polyethylene wax has good affinity with alkaline pigments, so it can disperse the pigments well and make the colors more bright.

3. Good smoothness. The oxidized polyethylene wax has good smoothness in plastic processing due to the introduction of polar groups in the oxidation process, which reduces the processing temperature, makes demoulding easy, and makes the product surface bright.

4. With the increase of oil solubility, the oxidation product is a complex mixture, which can adjust the oxidation depth, match the solubility parameters of the oxidized wax and flux oil, and improve the solubility.

Oxidized polyethylene wax (OPE) has a certain amount of hydroxyl groups on the molecular chain of oxidized polyethylene, and their compatibility with polar resin is significantly improved, which is superior to polyethylene wax. It has good compatibility with rubber, plastic, paraffin and other materials. It has a balanced effect on the inner and outer smoothness of PVC; The smoothness of rigid transparent PVC formula with oxidized polyethylene wax is better than that of other smooth agents. Acid value greater than 13 can be regarded as emulsified type.

Scope of application

1. It is used as internal dispersant in color masterbatch processing.

2. It can improve the softening point of wax products, increase the strength of wax products, and make the appearance glossy. When the candle is lit, it will extinguish safely, and there will be no black smoke in the light.

3. PVC profiles, pipes and plastics are used as internal smoothing agents during the molding process, which can improve the toughness of plastic products, make the surface of products smooth and have a high qualification rate.

4. In the production process of PVC film, it can improve the gloss and transparency of the film, and improve the vertical and horizontal toughness of the film.

5. It can be used as dispersant for printing ink and paint to improve scratch resistance, friction resistance and coloring degree; It has a good anti sinking effect, so that the printed matter has a good luster and three-dimensional sense.
