Explained: Delta E & Why It Matters In the world of plastic color matching, Delta E (ΔE) is the standard measurement for color difference—and one of the most important metrics for quality control. But what does it actually mean, and why should processors and OEMs care? What is Delta E? Delta E is a numerical value that represents the difference between two colors in a [...]

Moisture, Bubbles, and Color: Why Proper Resin Drying is Critical for Appearance 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 [...]

Pigment Behavior: High vs Low Heat Processing 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. [...]

Top Color Challenges : Injection vs Extrusion 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. [...]
