Ethylene bis-stearamide (EBS): white or milky white powder or granule. Relative density 0.98, molecular weight 593, melting point 142 ℃, insoluble in water, soluble in hot chlorinated hydrocarbons and aromatic solvents. It is widely used as a lubricating agent, anti-sticking agent, lubricant and antistatic agent. Non-toxic, suitable for internal and external lubricants of PE, PP, PS, ABS resins and thermosetting plastics. The general dosage is 0.2%~2.0%.

Calcium stearate is an organic compound with the molecular formula of C36H70CaO4. It is a white powder, insoluble in water, and can be used as a waterproof agent, lubricant and plastic additive. Today, Qingdao Sainuo will take you to understand the use of calcium stearate in various industries.

The aluminate coupling agent has the characteristics of large reaction activity with inorganic powder surface, light color, non-toxic, small taste, high thermal decomposition temperature and convenient use. In the PVC filling system, aluminate coupling agent has good thermal stability synergy effect and certain wetting and plasticizing effect. Therefore, aluminate coupling agents are widely used in various inorganic fillers, pigments and flame retardants.

EBS is the abbreviation of Ethylene Bis Stearamide, which is a synthetic wax with high melting point. Ethylene bisstearamide, a new plastic lubricant developed in recent years, 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, stearate, etc., it not only has good external lubrication effect, but also has good internal lubrication effect, which improves the fluidity and demoulding property of melted plastic in plastic molding process, thus improving the yield of plastic processing, reducing energy consumption, and making the product obtain high surface smoothness and smoothness.

Although polyethylene wax has a "small body", it has already shown itself in many fields by virtue of its functions of lubrication, demoulding, brightening, aging prevention and water loss prevention. Today, Sainuo will take you to know the matching of polyethylene wax related applications.

In the previous article, we briefly introduced the characteristics oferucic acid amide and its application in plastic processing. In this article, Sainuo will take you to understand the application of erucic acid amide in masterbatch and other industries.

Erucic acid amide, as an important derivative of erucic acid, is an excellent fine chemical product with a wide range of applications. Because of its high melting point and good thermal stability (stable at 273 ℃), it is mainly used as an anti adhesion agent and a smoothing agent for various plastics and resins, as well as an excellent lubricant and antistatic agent for extruded films.

Oxidized polyethylene wax is an extremely efficient PVC lubricant. Upgrade on the basis of polyethylene wax to meet PVC products with higher processing difficulty. It has excellent external lubrication, strong internal lubrication and coupling effect, which can improve the production efficiency of plastic processing and reduce production costs.

The setting of PVC formula system and the selection of various additives are important factors to ensure the quality of PVC profiles. In addition to the stable system and the modified system, the polyethylene wax of the lubricating system has a great influence on the processing properties of profiles, the appearance of products and various physical properties. Due to its small amount, its important role is often ignored. Many defects in PVC profile processing and products are closely related to the selection and proportion of lubricant polyethylene wax. Therefore, the lubricant polyethylene wax plays a very important role in PVC profile formulation.

Ethylene bis stearamide / EBS wax is white fine granules or powder with high melting point, non-toxic, insoluble in water, stable to acid, alkali and water medium, but the powder is wettable above 80 ℃. EBS is a multifunctional plastic additive, which is widely used in the production and processing of ABS resin, PVC, polypropylene, phenolic resin and amino resin as internal and external lubricant, as well as anti adhesion agent, release agent, antistatic agent, viscosity regulator and surface brightener. Today, Qingdao Sainuo will show you the application fields of EBS.

Polyethylene wax and paraffin wax are widely used in industrial production due to their excellent performance, but they are different. In this article, Qingdao Sainuo​ will briefly introduce the differences between polyethylene wax and paraffin wax.

Polyethylene wax has good chemical stability, excellent mechanical properties, electrical properties, dispersibility, fluidity, and demoulding properties. It has high softening point, low melt viscosity, high hardness, and good wear resistance. As a dispersant for various masterbatches, a release agent for polyolefin processing, and 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 expanded to engineering plastics with higher performance requirements and rapid development momentum.

Polyethylene wax is widely used as homopolymer or copolymer of low content polyethylene in coatings. The main functions of polyethylene wax in solvent based coatings are: matting, scratch resistance, abrasion resistance, polishing resistance, engraving resistance, adhesion resistance, precipitation resistance, thixotropy; Good lubricity and processability; Positioning of metallic pigments.

PE wax​ / polyethylene wax is a mixture of hydrocarbons, low molecular weight polyethylene (molecular weight is about 2000~5000) and paraffin wax containing about 18~30 carbon atoms. The main components are straight chain alkanes (about 80%~95%), and a small amount of alkanes with single branch chains and single ring alkanes with long side chains (the total content of both is less than 20%).

Before selecting the coupling agent, the moisture content of the filler used shall be determined first, and the specific type shall be determined according to the moisture content state and the characteristics of the aforementioned aluminate coupling agents. The dry filler should be monoalkoxy type, and the wet filler can be chelating type or monoalkoxy pyrophosphate type. When selecting aluminate coupling agent, the melting point, crystallinity, molecular weight, polarity, aromaticity, fatty foot, copolymer structure, etc. of the polymer should also be considered. For thermosetting polymers, the curing temperature and curing mechanism should also be considered.
