| Grade | Melting Point | Migration Speed (Slip Rate) | Thermal Stability | Strengths |
| Oleamide | ~68ā76Ā°C | Fastest | Low | Immediate slip; fast COF reduction in PE/PP |
| Erucamide | ~78ā85Ā°C | Medium-Fast | Good ~240Ā°C | Industry standard film slip agent & cap lubricant |
| Stearamide | ~98ā105Ā°C | Slow-Medium | High | Mold release, internal lubricant, antiblock |
| Behenamide | ~108ā115Ā°C | Very Slow | Very High | High-temp antiblock; zero impact on printability |
| Octadecyl Erucamide | ~72ā78Ā°C | Controlled / Slow | Excellent (>300Ā°C) | High-temp slip; non-blooming, print/seal friendly |
| Ethylene Bis Oleamide (EBO) | ~115ā125Ā°C | Slow / Internal | Very High (>280Ā°C) | High-temp lubricant, anti-tack, mold release |

Selection Guide of slip agent
For rapid film opening and low cost ā Oleamide
For standard PP/BOPP packaging films and long-lasting slip ā Erucamide
For multilayer co-extrusion, nylon retort films, and applications requiring no interference with printing/lamination ā Stearyl Erucamide
For masterbatch dispersion, gloss enhancement in modified plastics, and anti-blocking in EVA hot-melt adhesives ā EBO Ethylene bis-oleamide
Anti-blocking and mold release for rigid products; processing lubricant for PVC/ABS ā Stearamide
High-temperature engineering plastics; ultra-low migration; long-term aging resistance ā Behenamide
Summary of structural differences
Primary amides (oleamide, erucamide): Primarily for film surface slip and easy opening; significant migration
Secondary amides (stearyl erucamide): Low-migration slip; suitable for multilayer composite films.
Bis-amides (EBO): Primarily for internal melt lubrication, dispersion, and gloss enhancement; not a film slip agent.
Things to know about using slip agent
- Exceeding the recommended dosage can lead to blooming and adversely affect printing, aluminizing, or lamination bond strength.
- In multilayer co-extrusion, high-migration amides (such as oleamide) must not be placed adjacent to nylon or EVOH barrier layers; migration across layers can cause delamination and poor heat-sealing performance.
