What Is the Best Way to Measure the Colour of Opaque and Transparent Pellets?

A spectrophotometer is the best way to measure the colour of opaque and transparent pellets. The colour measurement solution enables you to maintain colour consistency to meet industry standards and improve the pellets' appearance.

Measure Pellets With the Right Equipment

When measuring the colour of opaque and transparent pellets, it is essential to utilize a spectrophotometer that considers opaqueness and transparency. Spectrophotometers that measure reflectance are well-suited for evaluating both opaque and transparent pellets.

Prepare Your Samples

A standard procedure needs to be implemented when preparing and presenting samples. Having procedures that everyone follows helps limit any inconsistencies between samples to ensure more accurate results. Consider developing a repeatable sample preparation method for repeated results.

Maintain Industry Standards When Measuring

The colour of opaque and transparent pellets must adhere to the standard test method for colour determination of plastic pellets. The ASTM standard outlines the ideal testing methods and measurement processes. A spectrophotometer allows you to optimize your colour measurement process, helping you maintain industry standards. 

Measure Objectively

The human eye can assess the colour of opaque and transparent pellets. However, people's perceptions of colour can vary, which makes the assessment subjective. Other factors, such as lighting, viewing angle, and even texture, can also impact the perception of a specific colour.

A spectrophotometer offers an objective measuring process that yields more accurate and consistent results. With this advanced solution, the factors can be controlled, and the colour of the resin pellets can be quantified through numerical representation. 

Use the Data to Your Advantage 

It's important to analyze the data you gather after measuring each sample with a spectrophotometer. The data helps you maintain colour consistency and meet industry standards. A spectrophotometer also highlights inconsistencies, allowing you to make the necessary adjustments to your manufacturing process. 

Integrate ESG Considerations Into the Measurement Process

With increased environmental awareness and evolving regulations, improving Environmental, Social, and Governance (ESG) performance has become crucial in the plastic manufacturing industry.

Implementing accurate measurement practices using HunterLab spectrophotometers allows you to detect and correct colour issues before mass production. As such, you can reduce product and energy waste and carbon emissions. Our solutions cover the raw materials, converted plastics, recycling, and feedstock segments of the circular economy.
