EBS, also known as “ethylene bisstearamide”, is white or light yellow in color and resembles a solid wax. It is a hard and tough synthetic wax. (Hereinafter, ethylene bis stearamide is abbreviated as EBS)
Sainuo EBS uses imported stearic acid raw materials, which has a very high carbon content and can completely replace Kao and Malay products in terms of dispersing properties.
What is the main role of EBS?
EBS can be used as: internal and external lubricants, antistatic agents, nucleating transparent agents, dispersants, mold release agents, anti-caking agents, matting agents, deaerator opening agents (anti-bonding), non-silicone defoamers, And increase the fat (MI) and so on.
What are the advantages of EBS?
High whiteness, low acid value, low amine value, high temperature resistance and excellent thermal stability.
The principle of action of EBS
Internal lubricant: Due to the presence of polar amide groups in the EBS molecule, it has a processing lubrication effect on the polymer resin and a low-temperature anti-sticking effect. EBS can be inserted into the polymer resin to reduce the interaction between the resin molecules.
External lubricant: EBS has limited compatibility with the resin and can be pulled from the inside of the resin to the surface, which reduces the mutual friction between the resin particles, the resin melt and the processing equipment, and prevents it from adhering to the metal surface.
EBS is used as a lubricant release agent in plastic processing to improve the quality of plastic products and improve the appearance of products.
