- ▸ Used as an internal and external lubricant in PVC, polyolefin and engineering-plastic compounding to reduce melt viscosity, improve flow and prevent metal sticking during extrusion and injection molding.
- ▸ Functions as a slip and anti-block agent in plastic films and masterbatches, lowering the surface coefficient of friction so films separate and feed cleanly.
- ▸ Serves as a mold-release and dispersing aid for pigments and fillers in color masterbatch, helping wet-out and uniform distribution of carbon black and inorganic pigments.
- ▸ Applied as an anti-foaming and defoaming agent in asphalt, paper coatings and adhesives where its high-melting wax structure collapses foam.
- ▸ Used as a flow modifier and lubricant in powder-metallurgy, rubber processing and hot-melt formulations to ease release and reduce die drag.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.

Ethylene bis-stearamide (EBS) is a bis-amide wax used as a lubricant, slip and anti-block agent, mould-release and dispersant across plastics, rubber and industrial products. Identity: CAS 110-30-5.
What it is
Ethylene bis-stearamide (CAS 110-30-5, C38H76N2O2) is a high-melting bis-amide wax made from stearic acid and ethylenediamine. It combines lubrication with good thermal stability.
Industrial uses
It is used as an internal/external lubricant and processing aid in plastics (PVC, ABS, polyolefins, engineering plastics), a slip and anti-block agent, a mould-release agent, a pigment-wetting and dispersing aid (masterbatch), a defoamer and anti-caking additive, and a lubricant/release additive in rubber, asphalt and metal processing.
Forms, grades and handling
EBS is supplied as powder, beads or micronized grades in bags and bulk; specify particle form. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Always consult the current Safety Data Sheet (SDS) before handling, and confirm regulatory status and suitability for your application and jurisdiction. Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources Ethylene Bis-Stearamide direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us the grade, particle size or specification and quantity you need, and we will quote it. Products are sold for industrial and professional use.

Frequently Asked Questions
What is ethylene bis-stearamide (EBS) used for?
EBS (CAS 110-30-5) is a bis-amide wax used as a lubricant and processing aid in plastics, a slip/anti-block and mould-release agent, a pigment dispersant in masterbatch, and a defoamer/anti-caking additive. RawSource supplies it for industrial use.
How is bulk ethylene bis-stearamide supplied and quoted?
RawSource supplies ethylene bis-stearamide in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade, particle size/specification and volume; submit an RFQ with your application and quantity.
What is the REACH and TSCA regulatory status of Ethylene Bis-Stearamide (EBS)?
Ethylene Bis-Stearamide (EBS) (CAS 110-30-5) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 203-755-6).
