Guide to the Application of EBS in Industrial Production

📝Product Overview

N,N’-Ethylene Bisstearamide (EBS) is a highly efficient, multifunctional synthetic wax-like amide compound with the chemical name ethylene bisstearamide and CAS number 110-30-5.

It appears as a white to light yellow powder or granules, odorless, and chemically stable. Its core characteristics lie in its dual internal and external lubricating properties, enabling it to migrate to the material surface during processing to form a lubricating layer, significantly reducing the coefficient of friction, enhancing melt flowability, demolding efficiency, and surface finish of the finished product.
