Many additives are used in the production of color masterbatch, but the most important one is polyethylene wax. Today, we will introduce the application of pe wax in the production of color masterbatch.

Lubricants and dispersants are widely used in daily industrial production. In this article, follow the footsteps of Sainuo to look at the application of oxidized polyethylene wax and EVA wax in various fields.

Polyethylene wax has good chemical stability, excellent mechanical properties, electrical properties, dispersibility, fluidity and demoulding. It has high softening point, low melting viscosity, high hardness and good wear resistance. As a dispersant of various masterbatches, a demoulding agent for polyolefin processing, a lubricant for polychloroethylene plastic processing, it is widely used in general plastic processing. Due to the introduction of polar groups, the physical properties of chemically modified polyethylene wax have been improved, so that the application field of pe wax has been extended to engineering plastics with higher performance requirements and rapid development momentum.

Calcium stearate is a white powder that is insoluble in water, cold ethanol, soluble in organic solvents such as hot benzene, benzene and turpentine, and slightly soluble in hot ethanol. It decomposes slowly when heated to 400 ℃ and is flammable. It decomposes into stearic acid and corresponding calcium salt when encountering strong acid and is hygroscopic. It is mainly used as stabilizer, lubricant​ , paint polish, lubricant for pencil lead, etc.

Oxidized polyethylene wax has low viscosity, high softening point, good hardness and other properties, and itself non-toxic, good thermal stability, high-temperature volatility, It has excellent dispersibility for fillers and pigments. It not only has excellent external lubricity, but also has strong internal lubricity and coupling effect. In PVC system, low density ope wax 629 can be plasticized ahead of time, and the later torque is reduced. It has excellent internal and external lubrication. It can improve the dispersity of colorant, give products a good luster and improve production efficiency.

EVA wax (hot melt adhesive) is widely applicable, such as PA (polypropylene), PA (polyethylene) and other non-polar materials, which can also achieve good bonding effect. The adhesive layer has good low temperature resistance, water resistance and moisture resistance.

Wax for coating is mainly added in the form of additives, initially used to improve the surface anti expansion performance of the coating film. Mainly including improving the smoothness, scratch resistance and waterproof of the coating film. In addition, it can also affect the rheological property of the coating, and its addition can make the orientation of solid particles such as aluminum powder in metal flash paint uniform. It can be used as a matting agent in matte paint. According to its particle size and particle size distribution, the matting effect of wax additives is different. Therefore, wax additives are suitable for both glossy and matte paints. Microcrystalline modified polyethylene wax can be used to improve the surface properties of waterborne industrial coatings.

Coupling agent is an important and widely used treatment agent, which is mainly used as auxiliary agent for polymer composites. The biggest characteristic of the molecular structure of the coupling agent is that the molecule contains two groups with different chemical properties.

Polyethylene wax and oxidized polyethylene wax​ are often used in the production of plastic industry. From the same point of view, both can be used as lubricants, but there are also differences between them. Today, through this article, let's take a look at the differences between polyethylene wax and oxidized polyethylene wax.

We know that oxidized polyethylene wax is an extremely efficient PVC lubricant. Upgrade on the basis of polyethylene wax to meet the requirements of PVC products with higher processing difficulty for plasticization and later demoulding. Which products must be added with oxidized polyethylene wax?

Color masterbatch is a new type of special colorant for polymer materials. It is mainly used in plastics. Today, follow the footsteps of Sainuo to learn some knowledge about additives in color masterbatch.

Sainuo high-density ope wax, it can promote plasticization, and it has a good post-thermal stability, it can give products a good plasticization and luster, long continuous production cycle, in masterbatch will increase dispersion and brightness, but it has an effect on the oxidative induction period.

Oxidized polyethylene wax is a new kind of excellent polar wax, which is made from polyethylene wax by special oxidation process. Its molecular chain contains a certain amount of carbonyl and hydroxyl groups, so it has good compatibility with rubber, plastics, paraffin, pigments, fillers and polar resins. It is white with yellowish powder particles and has good chemical stability.

Calcium stearate, white powder, insoluble in water, cold ethanol and ethyl alcohol, soluble in organic solvents such as hot benzene, benzene and turpentine, slightly soluble in hot ethanol and ethyl alcohol. When heated to 400C, it decomposes slowly and is flammable. In case of strong acid, it decomposes into stearic acid and corresponding calcium salt, which has hygroscopicity. It is mainly used as stabilizer, lubricant, paint smoothing agent, lubricant for pencil lead, etc. Sainuo​ calcium stearate has no sulfur pollution, with good long-term thermal stability, good lubrication and demoulding performance.

Polyethylene wax is widely used in color masterbatch dispersion, road paint, water-based paint, plastic dyeing, printing ink, paraffin, plastic processing lubrication, etc. today, Sainuo will take you to understand the role of polyethylene wax in these industries.
