In people's lives, the application of plastic products is ubiquitous, and color masterbatch is usually used in plastics materials. Color masterbatch is a new type of professional colorant for polymer materials. Masterbatch consists of pigments, carriers and additives. In general, the carrier is a thermoplastic resin, which has good wetting and dispersing effects on the colorant, and has good compatibility. Color masterbatch is currently the most common plastic coloring method. And do you know the precautions when using color masterbatch for your plastic packaging materials? This article will give your the answer.
How to determine the proportion of color masterbatch?
In fact, the use of color masterbatch is very simple, as long as it is fully mixed with plastic resin in a certain proportion, and it can be extruded to meet various plastic processing requirements. There are some proportion that can be used mixed. They are 1:100, 1:50, 1:33--1:25 and 1:20. Different ratios are often applied to different plastic products. For example, 1:50 is used for plastic products with general coloring requirements, and PE color masterbatches and PP color masterbatches are mostly used in this ratio.
Do masterbatches need to be dried before use?
Generally, the color masterbatch does not need to be dried and can be used directly. However, except for ABS color masterbatch, they should be dried according to the conventional process.
How long is the shelf life of the masterbatch?
The color masterbatch can be stored for a long time. The pigments in the masterbatch are dispersed and fixed in the carrier resin, in a closed state, and their quality will not change even if they are stored for a long time. However, it should be stored in a dry, cool environment.
Will the use of masterbatch affect other properties of the product?
Some pigments have an impact on the flame retardant effect of the product. For example, when used in flame retardant products, it should be pointed out to the color masterbatch manufacturer.
How many different masterbatches can be used to formulate the color?
Generally, companies often use several color masterbatches to formulate specific colors for small-volume customers. However, without the guidance of the company's technical personnel, the customer cannot use several color masterbatches on their own, let alone mix the color masterbatches produced by different companies, so as to avoid losses caused by incompatibility.
In addition, in the process of using the masterbatch, it is also necessary to pay attention to the fact that the mold needs to be smooth and cannot contain impurities. In order to fully display the coloring effect of the color masterbatch, the mold must have the corresponding quality and the surface needs to be very clean and smooth.
