一、 What is the color masterbatch?

Masterbatch is a new type of special colorant for polymer materials. Simply put, masterbatches are aggregates made by uniformly loading supernormal amounts of pigments or dyes into resins. 2. What are the basic components of color masterbatches? The basic components of masterbatch are: 1. Pigments or dyes, which are divided into organic pigments and inorganic pigments.

二、 Carrier is the matrix of color masterbatch.

Specialized masterbatches generally choose the same resin as the product resin as the carrier. The compatibility between the two is the best, but the fluidity of the carrier should also be considered. Dispersant: Promote the uniform dispersion of pigments and no longer condensate. The melting point of the dispersant should be lower than that of the resin. It has good compatibility with the resin and good affinity with the pigments. The most commonly used dispersants are polyethylene low molecular wax and stearate. Additives: such as flame retardant, brightening, antimicrobial, antistatic, antioxidant and other varieties, unless the customer requests, in general the color masterbatch does not contain the above additives.

三、 What varieties and grades are the color masterbatches?

There are several commonly used methods to classify masterbatches according to carriers, such as PE, PP, ABS, PVC and EVA masterbatches. For example, injection, blow moulding and spinning masterbatches are generally suitable for plastics used in products. They can be safely used at normal temperatures. Only in the following circumstances will cause varying degrees of discoloration, one is that the temperature exceeds the normal range, the other is that the downtime is too long. Compared with granulation coloring, masterbatch coloring has the following advantages: coloring and product processing are completed at one time, avoiding the heating process of granulation coloring on plastics, which is good for protecting the quality of plastics products.

四、 Why use color masterbatches?

The use of masterbatches has the following advantages:

1. Make the pigments have better dispersibility in the products: masterbatch is an aggregate made by uniformly loading super-large amount of pigments into the resin.

2. Guarantee the stability of product color.

3. It is helpful to maintain the chemical stability of pigments.

4. Protect the health of operators.

5. Keep the environment clean and free from contamination.

6. Simple process, easy color change, saving time and raw materials.
