Ethylene bis (stearamide) cas 110-30-5 is a new type of plastic lubricant developed in recent years, widely used in PVC products ABS、 In the molding process of 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 effect, but also has good internal lubrication effect, which improves the flowability and demolding of the melted plastic in the plastic molding process, thereby increasing the yield of plastic processing, reducing energy consumption, and achieving extremely high surface smoothness and smoothness of the products.
Due to the presence of two amide groups "- C-NH -" in its molecular structure, EBS, when added to plastics, gives plastic products good anti-static properties and makes them less prone to "vacuuming" and getting dirty. This valuable and excellent characteristic is particularly important for use in home appliances, instrument casings, and numerous engineering plastic products. As a lubricant, EBS has a significant synergistic effect when used in combination with other lubricants such as zinc stearate. Improve the dispersibility of other components such as colorants and fillers in plastics.
This product can be used for the following types of plastic products:
Plastic processing: Due to the presence of polar amide groups in EBS molecules, EBS has processing lubrication and low-temperature anti sticking effects on polymer resins. EBS can be inserted into polymer resins to reduce intermolecular interactions and provide internal lubrication. On the other hand, EBS can also serve as an external lubricant to prevent resin melt from adhering to metal surfaces. Therefore, EBS is mainly used as a lubricating release agent in plastic processing to improve the quality and appearance of plastic products. It also plays a role in anti sticking, smoothness, anti-static, improving pigment dispersion, and assisting stability.
1. Hard polyvinyl chloride products: increase the flowability of hard polyvinyl chloride during melting. This additive is mainly used as an internal and external lubricant, as well as an anti adhesive agent. Even if 2 parts are added, it will not affect the transparency. The application of EBS in the production of PVC hard sheets can improve the flowability of materials and prevent material agglomeration.
2. Soft polyvinyl chloride products: This product is a very effective anti adhesion agent in the production of soft polyethylene film
The amount of lubricant added is 1-2% depending on the thickness of the processed film. The application of EBS in the production of soft PVC conveyor belts can reduce the processing current by 8-10A, save power consumption, and improve the film-forming opening effect.
3. Polyolefin: can be used as an opening agent or lubricant for the production of polyethylene and polypropylene films or sheets, and can be used as an external lubricant and release agent for ethylene vinyl acetate products.
4. ABS engineering plastics and polystyrene: can enhance the flowability of ABS and polystyrene. The addition amount for ABS can reach 4%, while for polystyrene, printing or coloring must be considered, and the addition amount is determined according to experimental conditions.
5. Polyamide: Used for PA6, a small amount of addition can achieve the effect of an internal release agent. Sometimes, extremely fine powder of this additive is sprinkled into PA particles.
6. In the thermoplastic PUR injection molding process, this additive also serves as an internal release agent, with an added amount of 0.1-1%.
7. Polyoxymethylene (POM): EBS is used as a polyoxymethylene lubricant, which has a good application effect. Adding 0.5% EBS to polyoxymethylene increased the melt flow rate, improved demolding properties, and the whiteness, thermal stability, and various physical indicators of polyoxymethylene reached the standards of high-quality products.
8. Phenolic resin: In casting processing, adding EBS to the mixture of resin and sand can not only lubricate demolding, but also increase its strength. Adding 3-5% EBS can increase its tensile strength by 10-20%.
9. Pigments and filler dispersants: In plastic masterbatch and modified plastic additives, the dispersibility and dosage of pigments and fillers can be improved, processing efficiency can be enhanced, and the brightness and brightness of masterbatch can be improved. The dosage is 0.5-5%.
Other uses:
In the rubber industry, this additive can be used as an anti sticking agent, lubricant, and release agent for rubber materials, as well as a surface treatment agent for hard rubber. This product can also be used as a melting point rising agent for petroleum products, a lubricant and corrosion inhibitor for metal wire drawing. In the paper industry, it can be used as a waterproofing agent, defoamer, component of paper coatings, and sealing material for electrical components. Can be used as a matting agent in furniture polishing agents and printing inks. In the production of asphalt, paraffin, and resin, EBS can reduce viscosity, increase softening point, improve waterproofing, and enhance resistance to salt water, acid, and alkali; Adding a small amount of EBS to the wax mixture can improve its anti caking, anti sticking, and demolding properties
