The Advantages of Erucamide Wax for PVC Production

by:Sainuo     2023-06-26

Erucamide wax is an excellent processing aid used in polyvinyl chloride (PVC) production that helps achieve better processing efficiency, smoother surfaces, and reduced die build-up. This type of wax is a chemical compound that has the ability to modify the surface characteristics of materials, which is why it is commonly used in the plastics and rubber industry.

In this article, we will discuss the numerous advantages of using erucamide wax in the PVC production process. We will delve deep into the properties of erucamide wax, its applications, and the benefits that it provides.

What is Erucamide Wax?

Erucamide wax is a fatty acid-based wax that is derived from erucic acid, which is a key component in rapeseed oil. This wax is usually added to PVC formulations in small amounts (typically 0.5% - 2%), before the melting and extrusion process has begun. This helps to improve the characteristics of the PVC during processing.

Properties of Erucamide Wax

Erucamide wax has a range of properties that make it a suitable material for use in PVC processing. These properties include:

1. High Slip: Erucamide wax enhances the slip properties of PVC surfaces by reducing friction between different parts in the production line. This helps to minimize adhesion between PVC surfaces, which makes processing more efficient.

2. Low Melting Point: Erucamide wax has a low melting point of approximately 77°C, which means it can be easily dispersed within PVC formulations at relatively low temperatures.

3. Good Compatibility: Erucamide wax has good compatibility with PVC and other polymers. This helps to ensure uniform distribution of the wax within the formulation.

4. Low Toxicity: Erucamide wax is non-toxic and is not harmful to humans or the environment. This makes it a safe processing aid to use in PVC production.

Applications of Erucamide Wax in PVC Production

Erucamide wax is primarily used in PVC production to improve the processing of polymers. Some of the key applications of erucamide wax in PVC production include:

1. Improved Flow Properties: Erucamide wax helps to improve the flow properties of PVC formulations by reducing friction between particles and other surfaces during processing.

2. Reduced Die Build-Up: PVC formulations tend to stick to the inner surfaces of the extrusion die during the production process, which can lead to reduced production efficiency and quality issues. Erucamide wax helps to reduce die build-up, leading to smoother and more consistent production.

3. Improved Surface Appearance: Erucamide wax helps to improve the surface appearance of PVC products, making them more visually appealing.

4. Improved Mechanical Properties: Erucamide wax helps to improve the mechanical properties of PVC products such as resilience, hardness, and durability.

5. Better Lubrication: Erucamide wax helps to provide better lubrication between PVC surfaces, which can reduce energy consumption during processing and increase production efficiency.

Benefits of Using Erucamide Wax in PVC Production

The use of erucamide wax in PVC production provides several benefits, which include:

1. Improved Processing Efficiency: Erucamide wax helps to reduce friction between particles, leading to improved processing efficiency and consistent quality.

2. Cost Efficiency: Erucamide wax is an affordable processing aid that is easy to use and has a low melting point, making it a cost-efficient choice for PVC processing.

3. Reduced Waste: Erucamide wax reduces the amount of waste generated during production, leading to increased production efficiency and reduced environmental impact.

4. Enhanced Product Quality: Erucamide wax improves the mechanical properties of PVC products, leading to higher quality and durability.

5. Reduced Energy Consumption: Erucamide wax reduces friction between PVC surfaces, leading to reduced energy consumption during processing.


Overall, erucamide wax is an excellent processing aid that helps to improve the processing efficiency and quality of PVC products. It provides a range of benefits, including improved flow properties, smoother surface appearance, and better mechanical properties. Its low toxicity and affordable price make it a safe and cost-effective choice for PVC processing. If you're looking to enhance the properties and efficiency of your PVC production, consider using erucamide wax as your processing aid.
