EBS Wax Supplier
Product Overview
A versatile additive trusted across the global plastics industry
Ethylene Bis Stearamide (EBS) is a synthetic amide wax produced from the reaction of ethylenediamine and stearic acid. Marketed worldwide as a high-melting wax in white or pale-yellow bead, powder, or flake form, EBS combines exceptional lubricity, mold-release, and dispersion performance in a single additive.
Its broad polymer compatibility makes it suitable for nearly all thermoplastics and thermosets — from PVC, ABS, and polyolefins to engineering resins like PA and PC. EBS is insoluble in water and stable to acids, alkalis, and moisture, ensuring consistent performance under demanding processing conditions.
As an EBS wax supplier, Sychem supplies industrial-grade and high-purity EBS wax from established Chinese producers, with stable supply, consistent quality, and competitive pricing for global B2B buyers.

Performance Benefits
Six functions in a single additive
EBS uniquely combines lubricating, dispersing, and surface-modifying actions, making it one of the most cost-effective processing aids on the market.
01 / LUBRICATION
Internal & External Lubricant
Reduces melt viscosity and friction between polymer and metal surfaces, lowering torque and improving throughput in extrusion and injection molding.
02 / RELEASE
Mold-Release Agent
Forms a smooth interfacial film that allows easy demolding of thermosetting resins, urea-melamine moldings, and rubber parts without surface defects.
03 / DISPERSION
Pigment & Filler Dispersant
Enhances wetting and homogeneity of pigments, carbon black, calcium carbonate, and glass fibers — improving color uniformity and mechanical consistency.
04 / ANTI-BLOCK
Anti-Blocking & Slip
Prevents film and sheet from sticking together; eliminates fish-eye defects in blown film and improves bag-opening for packaging applications.
05 / ANTISTATIC
Antistatic Performance
Reduces surface resistivity of finished plastics, minimizing dust pickup and static-related defects in electronics housings and powder coatings.
06 / SURFACE GLOSS
Surface Brightness & Gloss
Compensates for mold imperfections and contributes a smooth, glossy finish — particularly valued in rigid PVC profiles and ABS appliance parts.
Industries Served
Applications across plastics, rubber & beyond
EBS is used by compounders, masterbatch producers, and end-product manufacturers in five major application segments.
Plastics Processing
Internal & external lubricant for ABS, PS, PVC, PA, PC, polyolefins. Improves melt flow, reduces die buildup, prevents screw sticking. Recommended dosage 0.1 – 0.5%.
Masterbatch & Pigments
Premier dispersant for color masterbatch, white masterbatch, and filler masterbatch. Ensures uniform pigment distribution and prevents agglomeration during compounding.
Rubber Processing
Release agent for tire, fluororubber, and EPDM compounding. Improves Banbury kneading, vulcanization performance, and finished surface gloss.
Coatings & Inks
Micronized EBS provides anti-blocking, slip, scratch resistance, and water-repellency in solvent-based and water-based coatings, with minimal impact on transparency.
Nucleating & Engineering Plastics
Acts as a transparent nucleating agent in polyolefins, POM, and polyamide — shortens nucleation time, refines crystalline structure, improves mechanical properties.
Other Industrial Uses
Powder metallurgy lubricant; asphalt softening modifier; antifoaming agent in paper/textile production; anti-slip additive in adhesives and hot-melts.

EBS wax FAQ
What is EBS wax?
EBS wax is ethylene bis stearamide (CAS 110-30-5), a synthetic amide wax made from ethylenediamine and stearic acid. It is supplied as white to pale yellow beads, powder or micronized powder, melts at about 140–145 °C and is used as a lubricant, mold-release agent and dispersant in plastics, rubber and coatings.
Is EBS wax the same as stearamide wax?
In trade, “stearamide wax” usually means EBS. Strictly, stearamide (CAS 124-26-5) is a different, single amide that melts near 100 °C and is mainly used as a slip agent. When you source stearamide wax as a lubricant or dispersant, check that the CAS number is 110-30-5 and the melting point is about 140–145 °C.
How much EBS wax should I add?
As an internal and external lubricant in PVC, ABS, PS, polyolefins, PA and PC, a typical dosage is 0.1–0.5%. Color and filler masterbatch often uses more, because EBS also disperses the pigment or filler. Start low and adjust to torque, flow and surface quality.
What is the difference between EBS wax, zinc stearate and PE wax?
EBS wax works as both an internal and an external lubricant, disperses pigments well and stays stable at higher processing temperatures. Zinc stearate is a metal soap that also acts as an acid scavenger and release agent, but it is not used where metal ions or haze are a problem. PE wax is mainly an external lubricant and dispersant for PVC and masterbatch. For high-temperature or lasting surface effects, compare PETS and silicone masterbatch in our silicone masterbatch vs EBS wax guide.
Which form of EBS wax should I choose?
Beads are dust-free and dose easily in compounding. Powder disperses faster and suits masterbatch and dry blends. Micronized EBS is used in coatings and inks for slip and anti-blocking, and emulsions suit water-based systems. For engineering plastics processed above about 280 °C, consider PETS instead.
How do I order EBS wax from SYCHEM TECH?
As an ethylene bis stearamide supplier, we ship from a minimum order of 1 tonne, with about two weeks lead time for stock grades, by FCL or LCL. Tell us your polymer, process and preferred form, and we will email the TDS, COA and SDS and arrange a sample. Contact our team or write to info@sychemtech.com.
