The full name of the color masterbatch is color masterbatch, also known as color, is a new type of polymer material special coloring agent, also known as pigment preparation. Masterbatches are mainly used in plastics. The color master is composed of three basic elements: pigment or dye, carrier and additive. It is the aggregate of super constant pigment uniformly attached to resin, which can be called pigment concentrate, so its coloring power is higher than the pigment itself. During processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the coloring resin or product with the design pigment concentration.
The heat resistance grade of the special masterbatch is generally suitable for the plastic used for the product, and can be used safely at normal temperatures. Only in the following cases will cause varying degrees of discoloration, one is that the temperature is out of the normal range, one is that the downtime is too long.
What is the difference between granulation coloring and masterbatch coloring?
Masterbatch coloring has the following advantages over granulation coloring:
1. Coloring and product processing are completed once, avoiding the heating process of granulation and coloring on plastics, which is good for protecting the quality of plastic products.
2. Make the production process of plastic products the most simplified.
3. Can save a lot of electricity with the masterbatch color products will not fade? There is no absolutely non-fading product, the use of master-colored products may still fade, but for different grades of products to different degrees, some are more obvious, and some are difficult to detect.
