1. Oleic acid amide
Oleic acid amide belongs to unsaturated fatty amide. It is a white crystalline or granular solid with polycrystalline structure and odorless. It can reduce the friction between resin and other internal friction films and transmission equipment in the processing process, simplify the operation of the final product, and increase the production. For example, as a lubricant for polyethylene processing, it can reduce the melt viscosity of resin particle molding and improve the fluidity.
Formula：CH3(CH2)7CH=CH(CH2)7CONH2
Molecular Weight：283.49
Appearance: White particles, or white powder

2. Erucic acid amide

Erucic acid amide, as an important derivative of erucic acid, is an excellent fine chemical product with a wide range of applications. Because of its high melting poingt and good thermal stability (stable at 273 ℃), it is mainly used as anti adhesion agent and smoothing agent of various plastics and resins, excellent lubricant and antistatic agent of extruded film.
Formula: CH3(CH2)7CH=CH(CH2)11CONH2
Molecular Weight: 337.58
Appearance: White particles, or white powder

3. Difference between oleic acid amide and erucic acid amide
The main uses of erucic acid amide are smooth, anti stick and bright; Oleic acid amide is open, lubricating and anti adhesion. They have similar but different uses. If the opening is made of general plastic, such as PVC / PE, oleic acid amide is the best, with good quality and low price. However, if it is used in some high-end plastics, such as PP / TPU / BOPP, erucic acid amide is used as the opening, and the properties of erucic acid amide are better than oleic acid amide, because the stable processing performance of erucic acid amide is better than oleic acid amide and does not turn yellow and age. In addition, erucic acid amide precipitates slowly, so the long-term friction coefficient of erucic acid amide is lower than that of oleic acid amide.
