PET masterbatch is widely used in our daily life. It is a polymer compound made by attaching pigment super constant to resin. Masterbatch coloring is a plastic coloring method that is more commonly used today. The colorant dispersed in the carrier is simply mixed with the natural resin and used to manufacture plastic products. The use of PET masterbatches has the following advantages:

1. Make the pigment have better dispersion in the product:

The color masterbatch is a polymer made by uniformly loading super constant pigments in resin. In the production process of color masterbatch, the pigment must be refined to improve the dispersion and coloring power of the pigment. The carrier of the special color masterbatch is the same as the plastic variety of the product, and has good matching. After heating and melting, the pigment particles can be well dispersed in the plastic of the product.

2. Help to maintain the chemical stability of the pigment:

When the pigment is used directly, because the pigment directly contacts the air during storage and use, the pigment will absorb water and oxidize. After being made into a masterbatch, the resin carrier isolates the pigment from the air and moisture, so that the quality of the pigment can not be long-term. change.

3. To ensure the stability of the product color:

The masterbatch particles are similar to the resin particles, which is more convenient and accurate in measurement, and will not stick to the container during mixing, and the mixing with the resin is more uniform, so it can ensure the stability of the added amount, thereby ensuring the stability of the product color.

4. Protect the health of operators:

Pigments are generally in powder form, easy to fly when added and mixed, and will affect the health of the operator after being inhaled by the human body.

5. The process is simple, the color is easy to change, saving time and raw materials:

Because the pigment directly contacts the air during storage and use, moisture absorption, oxidation, agglomeration and other phenomena will occur. Direct use will cause color spots on the surface of the plastic product. The hue is dark, the color is easy to fade, and it causes Dust is flying, which affects the health of operators. In the production process, the color masterbatch is mechanically processed, the pigment is refined, the pigment is mixed with the resin carrier and the dispersant, and the pigment is separated from the air and moisture, thereby enhancing the weatherability of the pigment and improving In addition to the dispersibility and coloring power of the pigment, the hue is bright. Because the shape of the masterbatch and resin particles are similar, it is more convenient and accurate in measurement, and will not stick to the container during mixing, so it saves the time of cleaning the container and the machine and the raw materials used for the machine.

The above is the advantage of PET masterbatch!
