Before color matching, we must first understand the purpose of the product, whether the material of the product used is PP, PE or PVC, etc. and then start to analyze the color matching according to the color of the plastic product.
One, Judging the application environment and requirements of the product according to the use of the plastic product, and the temperature of the application environment, and then according to these factors, consider the temperature of the masterbatch during processing and use for color matching.
Two, Color matching according to the resin properties of plastic products. Whether the resin is polyethylene or polypropylene, their composition is different. When color matching, it is necessary to understand the color, gloss, transparency, heat resistance, aging resistance, and strength of the resin.
Three, After completing the first two steps, we can match the color of the plastic product. In the process of color matching, it is necessary to comprehensively consider the characteristics of plastics and the requirements for pigments such as safety and environmental protection, and then select appropriate pigments for color matching according to the requirements.
In addition, the masterbatch color matching must adhere to three principles, namely a small amount, similar and complementary color principles, a small amount means that the less colorant the better. The performance should be similar, such as heat resistance should be close. prevent the introduction of complementary colors, also known as the complementary color principle.
