Enhancing Color Intensity in Plastic Coloring Applications


Plastic products have become an integral part of our daily lives, serving a wide range of purposes from packaging to construction. The color of these plastic products plays a significant role in their aesthetic appeal and marketability. Manufacturers are constantly on the lookout for additives that can enhance color intensity while maintaining the desirable properties of the plastic. Ethylene Bis Stearamide (EBS) has emerged as a promising additive in the world of plastic coloring applications. In this article, we explore the various aspects of EBS and its role in enhancing color intensity.

I. Understanding Ethylene Bis Stearamide (EBS)

Ethylene Bis Stearamide is a synthetic wax-like substance derived from ethylene and stearic acid. It is commonly used as a lubricant, dispersant, and release agent in various industries. However, in recent years, its application as a color enhancer in plastic coloring has gained significant attention. Its unique chemical composition allows it to effectively enhance color intensity without compromising the integrity of the plastic product.

II. Mechanism of Color Intensity Enhancement

The exact mechanism through which EBS enhances color intensity in plastics is not fully understood. However, researchers suggest several probable factors. One of the primary reasons is ethylene bis stearamide's ability to improve the dispersion of color pigments within the plastic matrix. By reducing pigment agglomeration, Ethylene bis stearamide ensures a more even distribution of color, resulting in enhanced color intensity.

III. Compatibility with Different Plastic Polymers

One of the key advantages of using EBS is its compatibility with a wide range of plastic polymers. It can be easily incorporated into various plastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS), among others. This versatility makes EBS a valuable additive for manufacturers across different plastic industries.

IV. Influence on Mechanical Properties

The addition of any additive to plastic has the potential to alter the mechanical properties of the final product. However, extensive research has shown that incorporating EBS in plastic coloring applications has minimal impact on the overall mechanical properties. Its low melting point and high compatibility with plastics allow it to disperse more uniformly, minimizing any negative effects on tensile strength, impact resistance, and other mechanical characteristics.

V. Enhancing UV Resistance and Stability

In addition to enhancing color intensity, EBS has demonstrated the ability to improve the UV resistance and stability of plastic products. Ultraviolet (UV) radiation is known to cause color fading and degradation of plastic, leading to reduced product lifespan. EBS acts as a protective shield, preventing UV radiation from penetrating the plastic matrix, thereby preserving color integrity and extending product longevity.

VI. Synergistic Effects with Other Additives

Many plastic coloring applications involve the use of multiple additives to achieve the desired color and performance characteristics. Ethylene bis stearamide has shown synergistic effects when combined with other additives such as antioxidants, light stabilizers, and anti-blocking agents. This synergy not only enhances color intensity but also further improves UV resistance and overall performance of the plastic product.


Ethylene Bis Stearamide (EBS) has emerged as an effective additive for enhancing color intensity in plastic coloring applications. Its compatibility with various plastic polymers, negligible impact on mechanical properties, and ability to improve UV resistance make it a preferred choice for manufacturers. With further research and development, Ethylene bis stearamide has the potential to revolutionize the world of plastic coloring, offering vibrant and durable products to consumers across industries.
