1. Product Overview
Erucamide (cis-13-docosenamide; CAS 112-84-5) is a primary fatty amide derived from erucic acid — a long-chain (C22) unsaturated amide used above all as a slip and antiblock additive in the plastics industry. When compounded into polyolefin films, it migrates to the film surface and forms a microscopic lubricating layer that sharply reduces the coefficient of friction (COF), giving film the easy slip and easy-opening character required by high-speed packaging lines. Its low volatility and high thermal stability make it the standard slip agent for polyolefin packaging films, plus a building block in anti-adhesive, release and lubricant formulations. Supplied as white to beige flakes or beads with a characteristic fatty odor, with full COA.
Core value propositions:
● Benchmark Slip Agent: reduces film COF for fast, reliable high-speed packaging;
● Low Volatility, High Stability: performs at elevated extrusion temperatures with low plate-out;
● Migratory Surface Lubricant: forms a durable micro-layer without bulk-film changes;
● Broad Formulation Use: films, anti-adhesive/release systems, lubricants and more.

3. Chemistry & Structure
Erucamide is a primary fatty amide: a 22-carbon monounsaturated chain (docosenoic acid skeleton) ending in a carboxamide group (−CONH₂), with the double bond at the 13-position in the cis (Z) configuration — structure CH₃(CH₂)₇CH=CH(CH₂)₁₁CONH₂. The molecule is amphiphilic in character: the amide head group is polar and capable of hydrogen bonding, while the long alkyl tail is strongly hydrophobic, giving a high logP of about 8. This two-faced architecture is the basis of its function: when the amide is blended into a polyolefin and the film cools, erucamide molecules migrate toward the film surface, where the polar amide heads anchor at the surface while the hydrocarbon tails orient outward, creating a thin, molecularly smooth lubricating layer that lowers the coefficient of friction. The cis double bond in the chain prevents tight crystal packing, which keeps the amide mobile and surface-active at use temperatures, while the hydrogen-bonded amide groups give the material a sharp melting point near 80 °C. As a longer-chain (C22) relative of C18 fatty amides, erucamide combines low volatility, thermal stability and a slow, controlled migration rate — the property profile that makes it the workhorse slip agent of the polyolefin film industry.

8. FAQ
Q1: What is erucamide used for?
Erucamide is a primary fatty amide used mainly as a migratory slip additive in polyolefin films (LLDPE, LDPE, HDPE, PP) to lower the coefficient of friction for high-speed packaging and easy film handling. It is also used in anti-adhesive/release systems, as a lubricant and friction-modifying additive, in specialty plastics and flame-retardant composites, in food-contact packaging films and adhesives, and in cosmetics for viscosity control and opacifying.
Q2: How does erucamide reduce the coefficient of friction?
Erucamide is a migratory additive: after compounding into the polymer, its small molecules slowly diffuse to the film surface, where the polar amide heads anchor while the long hydrocarbon tails orient outward, forming a molecular-scale lubricating layer. This surface layer lowers film-to-film friction without changing the bulk film properties. Because migration takes time, slip develops progressively after extrusion — film is typically 'slip-active' within a day or so — and the low volatility of the C22 amide keeps the effect lasting and stable.
Q3: What is the difference between erucamide and oleamide?
Both are unsaturated primary fatty amide slip agents, but they differ in chain length: oleamide is C18 with the double bond at position 9, while erucamide is C22 with the double bond at position 13. Erucamide's higher molecular weight and melting point (79–81 °C vs about 68–76 °C for oleamide) give it lower volatility and better thermal stability, so it is preferred for higher-temperature processes (cast film, BOPP, extrusion coating) and for applications needing lower haze and more durable slip. Oleamide acts faster at lower temperatures; erucamide is the more robust, longer-lasting choice for demanding packaging films.
