Is color master batch the best solution to color plastic products?

Color master batch is one of the indispensable ingredients for everyday plastic products. Besides color master batch, are there any other color-making methods that manufacturers often use? What are the advantages and disadvantages of these methods?

Comparing to color master batch, what is color powder better than masterbatch?

The second form of colorant used in masterbatch manufacturing is pigment powders. This is an inexpensive batch colors with color concentration is approximately 30-80%, dry color pigment is widely used in combination of filler masterbatch or pure resin. The cost of using dry pigment is negligible, but they do not have good color dispersion as color master batch. Besides, they also cause some discomfort such as contamination and dirtying of production machinery and surrounding environment because the particles are very light and easy to flutter. Another side effect of color powder is that it also makes it difficult to measure the exact amount needed.

Can batch colors in liquid form be used instead of color masterbatch?

Beside of master batch, paste color is plastic colorant in liquid form. However, the viscosity of it is more condense than the typical liquid masterbatch. Paste colorant is mainly used in masterbatches with polyvinyl chloride as base resin. Pigment concentration of paste color is quite high (30-60%) but its dispersibility is poor, hence manufacturers aimed to use this whenever they want to create plastic-based products with lightly or semi-transparent color appearances. This is the least common and also the least favorite type of batch colors since nearly all its properties are evaluated as poor or even very bad.

Color master batch of EuP is still the best solution to make color for plastic productsTo overcome the above disadvantages, color master batch is the most effective solution to help manufacturers solve the common limitations in coloring process. Batch colors in pellets (granules) is mixed with other materials such as filler masterbatch or additive in plastic production. Pigments in color master batch at high concentrations (10-70%) with excellent dispersion will give the finished product the most perfect appearance. When compared with pigments or solid color, the grain is more dominant in dispersion, storage stability as well as greater flexibility in use. Since then, the costs related to product preservation are also optimized. Not only that, in some cases, color masterbatch is also seen as a protective agent to cover and enhance the durability of plastic products.

In Europe, 60% of product relate to food are easily spoil due to low quality of cover packaging. Therefore, with the outstanding advantage are mentioned above, color master batch having all the characteristics for the new demand in plastic industry at the moment. In particular, masterbatch are durable in many different environment due to its well heat resistant which prevent food/drink from damaging. On the other hand, in the field of producing bottle water and yogurt, some factors such as appealing design, non-toxic, and eco friendly packaging are priority in this industry. Color masterbatch is used commonly in this industry since it protect the texture under UV rays and better contravene is better.
