A Comprehensive Guide to Using Erucamide Wax in Your Formulations

by:Sainuo     2023-07-04

Erucamide wax is an unsaturated fatty amide derived from erucic acid and ethylenediamine. It has been widely used as an effective slip agent, lubricant, and processing aid in various plastic applications. With its unique physical and chemical properties, erucamide wax can enhance the quality and performance of many plastic formulations. In this comprehensive guide, we will delve into the key features and benefits of using erucamide wax in your plastic formulations.


Erucamide wax belongs to a class of compounds called fatty amides. It is a white, waxy substance that is insoluble in water but soluble in organic solvents. Erucamide wax is typically produced by reacting erucic acid with ethylenediamine under controlled conditions. The resulting product is then purified and formulated into various grades for different applications.

Key Features and Benefits

Erucamide wax offers several unique advantages over other slip agents and lubricants. Some of the key features and benefits of erucamide wax are:

1. Improves Slip and Anti-Blocking Properties

Erucamide wax is widely used as a slip agent in plastic films and sheets. It reduces the coefficient of friction between the film and the processing equipment, resulting in smoother processing, improved quality, and increased productivity. Additionally, erucamide wax can improve the anti-blocking properties of plastic films, preventing them from sticking together during storage, transportation, and use.

2. Enhances Processing Efficiency

Erucamide wax can improve the processing efficiency of plastic formulations by reducing the melt viscosity and improving the melt flow. This can lead to faster processing speeds, lower energy consumption, and reduced processing costs. Moreover, erucamide wax can help to reduce die build-up and improve the surface finish of plastic products.

3. Provides Long-Term Stability

Erucamide wax is highly stable under a range of processing and storage conditions. It does not degrade or decompose easily, and it can maintain its properties for extended periods. This makes erucamide wax an ideal choice for applications that require long-term stability, such as food packaging and medical devices.

4. Compatible with Various Polymers

Erucamide wax is compatible with a wide range of polymers, including polyethylene, polypropylene, polystyrene, PVC, ABS, and nylon. It can be used in both single-polymer and multi-polymer formulations, providing maximum versatility and flexibility for plastic manufacturers.

5. Safe and Environmentally Friendly

Erucamide wax is a non-toxic, non-hazardous, and environmentally friendly material. It does not contain any heavy metals, volatile organic compounds (VOCs), or other harmful substances. Erucamide wax is commonly used in food contact applications and meets regulatory requirements in many countries.

Applications of Erucamide Wax

Erucamide wax has many applications in the plastics industry. Some of the common applications of erucamide wax are:

1. Film and Sheet Extrusion

Erucamide wax is widely used as a slip agent and anti-blocking agent in plastic films and sheets. It can improve the quality and processing efficiency of these products and enhance their performance during storage and use.

2. Injection Molding

Erucamide wax can be used as a processing aid in injection molding of various plastic parts. It can reduce the processing time, improve the surface finish, and reduce the risk of mold sticking.

3. Blow Molding

Erucamide wax can be used as a processing aid in blow molding of plastic bottles and containers. It can reduce the resin melt temperature, improve the parison stability, and enhance the final product quality.

4. Packaging

Erucamide wax is commonly used in food packaging applications, such as bags, wraps, and containers. It can improve the slip and anti-blocking properties of these products, prevent food contamination, and prolong shelf life.

5. Medical Devices

Erucamide wax can be used as a lubricant and processing aid in the production of medical devices, such as catheters, syringes, and IV bags. It can improve the molding process, reduce the risk of device breakage, and enhance the safety and efficacy of these products.


Erucamide wax is a versatile and effective additive for plastic formulations. It offers many unique features and benefits, such as improved slip, anti-blocking properties, processing efficiency, and long-term stability. Additionally, erucamide wax is compatible with a variety of polymers and is safe and environmentally friendly. By using erucamide wax in your plastic formulations, you can enhance the quality, performance, and value of your products.
