When it comes to color in plastics, the resin isn’t just the base—it’s the canvas. Every resin behaves differently in processing, interacts uniquely with pigments, and influences the final appearance of the part. That’s why understanding the natural characteristics of your resin is just as important as the color target itself. What is a "Natural" Resin? A “natural” resin is simply the base polymer in its uncolored, unfilled [...]
In plastics manufacturing, few things cause more hidden problems than moisture—especially when it comes to color consistency and surface appearance. Even a small amount of residual moisture in your resin can create visible defects, internal weaknesses, and costly rework. Many resins (especially hygroscopic polymers) naturally absorb moisture from the air. When these resins are processed at high temperatures without proper drying, the absorbed water doesn’t simply evaporate. Instead, it reacts with [...]
When it comes to plastics manufacturing, selecting the right pigment isn’t just about getting the color right. It’s about ensuring that the color stays right throughout the process and one of the most critical factors influencing color stability is processing temperature. Different pigments react differently under high-heat vs. low-heat conditions and understanding that behavior is essential for achieving consistent, high-quality results. Plastics are processed across a wide range of temperatures depending [...]
Color plays a critical role in both extrusion and injection molding—but the challenges in achieving consistent color differ significantly between the two processes. Knowing what to look out for can save time, scrap, and customer complaints. Key Color Challenges in Extrusion Line Speed VariabilityFaster or uneven extrusion speeds can affect pigment distribution, leading to inconsistent color bands. Melt Temperature FluctuationsEven slight temperature inconsistencies can alter color, especially with heat-sensitive pigments. [...]

Plastics have transformed 3D printing into one of the most innovative manufacturing methods available today. From prototyping to full-scale production, the versatility of plastics allows for a range of applications in industries like automotive, medical, aerospace, and consumer goods. But not all plastics are created equal. Each 3D printing technology relies on specific polymers with unique properties that affect strength, flexibility, and durability. FDM/FFF: The Most Accessible 3D Printing Technology Fused Deposition Modeling (FDM) or [...]
In color compounding for plastics, the terms opaque, translucent, and transparent describe how light interacts with the colored plastic, and these differences are critical for achieving the desired visual effects. More often than not, these terms can be confused due to their subtle differences in light transmission and visual appearance: Opaque: Opaque colors completely block the transmission of light, resulting in a solid, non-transparent appearance. Opaque colors are often used when the goal is to [...]
Color concentrate, dry color, and pre-color are all methods of adding color to plastics in the color compounding process, but they differ in their form and how they are incorporated into the plastic: 1.Color Concentrate: Color concentrate, also known as liquid color or color masterbatch, is a concentrated mixture of pigments or dyes dispersed in a carrier resin. It is typically in liquid or pellet form and is added to the base resin during the [...]
An easy way to transform the visual appearance of plastic products and enhance their appeal is by the use of special effect masterbatches. Special effect masterbatches are additives used in color compounding to achieve unique visual or tactile effects in plastic products. These concentrates contain a combination of pigments, additives, and sometimes special-effect components that impart specific characteristics to the final product. They are typically added to base resins during the compounding process to create [...]
Choosing the right resin is crucial in color compounding as it directly impacts the properties and performance of the final product. Different resins have unique characteristics such as strength, flexibility, chemical resistance, and processability. These properties influence how well the resin can be compounded with additives and pigments, how the color will appear, and how the product will perform in its intended application. For example, a resin with high chemical resistance may be preferred for [...]
