Polyethylene wax in a narrow sense is a kind of homopoly polyethylene with low relative molecular weight; Broadly speaking, polyethylene wax also includes modified polyethylene wax and copolymerized polyethylene wax. Generally, if a polyethylene polymer can not provide a certain strength and toughness like resin, and can not be processed as a single material into products with certain functions, we can classify it as polyethylene wax.

Oxidized polyethylene wax is an excellent new type of polar wax. Since the molecular chain of the oxidized polyethylene wax has a certain amount of carbonyl group and hydroxyl group, the compatibility with the filler, the pigment, and the polar resin is remarkably improved. The wettability and dispersibility in the polar system is better than that of the polyethylene wax, and it also has the coupling property, and its performance is comparable to that of the Honeywell A-C wax.

The color masterbatch is a plastic colorant composed of a high proportion of pigments or additives and thermoplastic resin. The selected resin has good wetting and dispersion effect on the colorant and good compatibility with the colored material. Today, Qingdao Sainuo polyethylene wax manufacturer takes you to know about color masterbatch.

Calcium stearate is a white powder, insoluble in water, cold ethanol and ether, soluble in organic solvents such as hot benzene, benzene and turpentine, and slightly soluble in hot ethanol and ether. When heated to 400, it decomposes slowly and is combustible. In case of strong acid, it decomposes into stearic acid and corresponding calcium salt, which has hygroscopicity. Qingdao Sainuocalcium stearate​ has no sulfur pollution, with good long-term thermal stability, good Lubrication and demoulding performance.

Ethylene bis stearamide​ is a new plastic lubricant developed in recent years. It is widely used in the molding and processing of PVC products, ABS, high impact polystyrene, polyolefin, rubber and plastic products. Compared with traditional lubricants such as paraffin wax, polyethylene wax and stearate, it not only has good external lubrication, but also has good internal lubrication, It can improve the fluidity and demoulding of melt separated plastic in plastic molding processing, so as to improve the output of plastic processing, reduce energy consumption, and make the products obtain high surface smoothness and smoothness.

Polyethylene wax​, also known as low molecular weight polyethylene and polymer wax, is abbreviated as PE wax. In recent years, the production scale and application field of polyethylene wax in China have developed rapidly. It has become a lubricant, brightener and dispersant in plastics, rubber, leather, paint, pigment, hot melt adhesive, candles, low-voltage electrical appliances, cosmetics and so on. This paper briefly introduces the application of polyethylene wax in PVC, modified masterbatch, color masterbatch and engineering plastics for reference.

Qingdao Sainuo pe wax SN9079W has stable index, high melting point, high hardness than oligomers, low weight loss, it can improve the processing performance of products; With good dispersion ability can replace the medium and high low polymer dispersion force, and solve the dispersion and lubrication capacity. Widely used in filler masterbatch, color masterbatch, transparent barium sulfate masterbatch, etc.

Aluminate coupling agent is used for the modification of inorganic filler surface activity. Its structure is similar to that of titanate coupling agent, There are two kinds of active groups in the molecule. One can interact with the surface of inorganic filler; The other can be entangled with resin molecules, resulting in coupling between inorganic filler and matrix resin. It has the characteristics of light color, non-toxic and easy to use. Its thermal stability is better than that of titanate coupling agent, and the price is only half of that of titanate coupling agent.

To make plastic film products, we can't do without stabilizer. What role do stabilizers play in plastic processing? What are the functions of stabilizers? What are the properties and application conditions of common heat stabilizers? This article Qingdao Sainuo Zinc Stearate manufacturer will share these problems.

There are two production processes of PVC transparent sheet, one is conventional calendering method, the other is extrusion calendering method, that is, it is produced by twin-screw extruder. It is the main hard PVC with the advantages of high light transmittance, smooth and bright surface, high physical and mechanical strength, corrosion resistance and high fineness. It is widely used in the fields of food, medicine, daily necessities and so on. There will be many problems in the production process of PVC, and the quality problems and solutions of calendering method and extrusion calendering method are also different due to different processes and equipment. This article pe wax manufacturer​ will discuss the common problems in the production process of PVC and put forward the corresponding solutions.

Plastic PVC colored products will fade under the influence of many factors. The fading of plastic colored products is related to the light resistance, oxygen resistance, heat resistance, acid and alkali resistance of toner and the characteristics of resin used. The following is a detailed analysis of the fading factors of plastic coloring by Qingdao Sainuo pe wax manufacturer:

Many PVC manufacturers will encounter precipitation problems in the production process. Today, Qingdao sainuo polyethylene wax manufacturer will take you to understand the relevant problems and solutions related to precipitation.

PVC pipe (UPVC pipe), is extruded by hot pressing method after the cooperation of polyvinyl chloride resin, stabilizer and lubricant. It is the earliest plastic material developed and applied. UPVC pipe has strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the leakage of UPVC monomer and additives, it is only suitable for water supply system with transmission temperature not exceeding 45 ℃.

Plastic modification is a method to change the properties and improve the quality of plastics by adding additives and fillers. At the same time, plastic modification is also the most effective way to reduce the cost of plastics. The elements of formula design in plastic modification mainly include: material selection, compounding, dosage and mixing mode. The interaction of various elements can be complementary or offset each other. Therefore, it is not easy to design a formula with high performance, easy processing and low cost.

In today's article, Qingdao sainuo polyethylene wax manufacturer will take you to learn about the blending modification of plastics.
