Oleamide is a short-chain fatty acid amide used as a fast-acting slip agent in plastic films. It migrates quickly to the surface, forming a lubricating layer that reduces the coefficient of friction (COF). Oleamide is ideal for applications where quick slip performance is needed, especially in PE, PP, and BOPP films.
| Property | Typical Value |
|---|---|
| Appearance | White to light yellow powder or flakes |
| Purity | ≥ 98% |
| Melting Point | 70 – 76 °C |
| Moisture | ≤ 0.2% |
| Iodine Value | 75 – 85 g I₂/100g |
| Problem | Oleamide Solution |
|---|---|
| High COF on film surface | Creates smooth surface with low friction |
| Blocking in film rolls | Prevents adhesion between film layers |
| Uneven winding tension | Improves slip and smooth winding |
| Need fast slip effect after extrusion | Oleamide migrates faster than Erucamide |
Q1: How is Oleamide different from Erucamide?
Oleamide works faster but has shorter slip duration; Erucamide offers long-term slip.
Q2: Is it safe for food-contact films?
Food-grade versions are available; confirm compliance based on your country regulations.
Q3: What is the normal dosage?
Typical usage is 0.1 – 1.0 phr depending on film thickness and line speed.
