How to measure the Color of Opaque and Transparent Plastic Pellets

In the world of plastics manufacturing, precision matters. Whether it’s extrusion or molding, getting the color right is crucial. Let’s explore how HunterLab helps the world's largest plastic manufacturers avoid yellowing in their products and repeatedly achieve accurate color.

Why Measure the Color of Opaque and Transparent Plastic Pellets?

Streamline Quality Control:
Color isn’t just aesthetics; it’s a quality indicator. Consumers rely on it, and manufacturers use it for optimal production. Opaque and transparent plastic pellets serve as raw materials for countless products. Accurate color during production ensures efficiency and minimizes wastage.

Tackle the Yellowing Challenge:
Plastic resin, like Polyethylene Terephthalate, tends to yellow due to oxidation. Optical brighteners are used to prevent this. But how much is enough? Accurate color assessment is critical to avoid yellowing.

Recycled Plastics and Environmental Impact:
Governments and standards bodies push for more recycled plastic. However, measuring color in recycled content is tricky. Color Spectrophotometers help adjust for yellowness, ensuring quality and reducing waste and revenue loss.

Regulatory Compliance:
Medical, food, pharma, and auto have strict material standards. Our spectrophotometers provide objective color data to demonstrate compliance.
