How Erucamide Wax Can Enhance the Processing of Thermoplastics

by:Sainuo     2023-06-26

Erucamide is a substance commonly used in the production of various plastic materials. It is derived from erucic acid, which is a type of fatty acid that is found in many plants, such as rapeseed, mustard, and wallflower. Erucamide wax has become increasingly popular in the plastics industry because of its unique properties and ability to enhance the processing of thermoplastics. This article will explore the benefits of erucamide wax and how it can improve the production processes of thermoplastics.

Benefits of Erucamide Wax

Erucamide wax has a wide range of benefits when it comes to processing thermoplastics. One of the main advantages of erucamide wax is its ability to improve the flow of plastic materials during processing. This is because erucamide wax has a low surface tension which helps the plastic materials flow more easily through machines, such as extruders and injection molding machines. With the addition of erucamide wax, the plastic materials are able to move through machinery more efficiently, leading to a more consistent and uniform product.

Another benefit of erucamide wax is that it acts as a lubricant. During processing, thermoplastics can often become sticky and difficult to handle. By incorporating erucamide wax, the plastic materials are lubricated, reducing the amount of friction between them and the machinery. This lubrication helps to prevent damage to the machines and also reduces the amount of downtime needed for maintenance.

Erucamide wax also has anti-blocking properties, which means that it helps to prevent plastic materials from sticking together during processing. This anti-blocking property is particularly useful in applications such as film production, where plastic sheets or films are produced in large quantities and need to be separated easily without any damage.

Enhanced Processing with Erucamide Wax

Erucamide wax is commonly used in the production of polyethylene films, which are widely used in a variety of industries, including packaging, construction, agriculture, and healthcare. Polyethylene films can be produced using a variety of different techniques, such as blown film extrusion or cast film extrusion. In both of these processes, erucamide wax can be added to the plastic material to enhance its processing and improve its final properties.

Blown Film Extrusion

Blown film extrusion is a process in which plastic pellets are melted and extruded through a circular die. The plastic is then inflated into a bubble and cooled to form a tube, which is later flattened to create a film. Erucamide wax is often added to the plastic pellets before they are melted in the extruder. This helps to improve the flow properties of the plastic material, reducing the amount of force needed to extrude the material through the die.

Erucamide wax also helps to reduce the amount of static electricity generated during the process. Static electricity can cause the plastic material to stick to the machinery, leading to defects in the film. By adding erucamide wax, the static electricity is reduced, and the film is produced more consistently.

Cast Film Extrusion

Cast film extrusion is a process in which molten plastic is extruded through a flat die onto a chill roll. The plastic material is then cooled and stretched to form a thin film. Erucamide wax can be added to the plastic material before it is extruded to improve the flow properties and to prevent the film from sticking to the chill roll. This helps to produce a more consistent film with fewer defects.


Erucamide wax has become an important additive in the plastics industry due to its ability to enhance the processing of thermoplastics. Erucamide wax has benefits such as improved flow properties, anti-blocking capabilities, and lubrication. By adding erucamide wax to plastic materials, production processes are made more efficient, resulting in a consistent and uniform product.

Erucamide wax is commonly used in the production of polyethylene films, particularly in blown film extrusion and cast film extrusion. The addition of erucamide wax in these processes helps to improve the flow properties, reduce static electricity, and prevent the film from sticking to machinery or the chill roll. Erucamide wax has become an essential component in the plastics industry and will continue to play a crucial role in enhancing the processing of thermoplastics.
