Master batches are an essential raw material for many industrial manufacturers because of their low price and stable performance. According to the global color processing industry statistics, the annual average demand for masterbatches has been increasing worldwide in recent years and has maintained an average growth rate of about 7-9% in the last five years. Due to the high demand, there are more and more color masterbatch manufacturers around the world. In China alone, there are more than 300 plastic grade masterbatch factories. Masterbatch manufacturers are constantly improving their production technology to increase the competitiveness of their products and attract more customers.

It is very important to use color masterbatches correctly. If used incorrectly, they can harm the final product. So no matter how simple it may seem, the effective application of colorants in injection molding needs to be given a great deal of attention. Injection molders can encounter many problems during the colorant incorporation process. One of the most serious negative effects is to cause a change in the color of the product, which means that all the design work done in the pre-production phase of the product is wasted. In addition, improperly proportioned coloring additives may also weaken the mechanical properties of the final product. This is mainly due to the incompatibility between the colorant and the original resin. Also, if the coloring process is hotter, the properties of the professional masterbatch will change. If the mold is hot, it compacts the plastic molecules before they solidify. This can result in denser parts, which can lead to darker colors in certain areas where PVC masterbatches are used.

 

To effectively apply colorants to your injection molded products, the first consideration is the compatibility between polymer chemistry and colorant chemistry. Secondly, you also need to ensure that your colorant has good thermal stability. The high level of heat used in injection molding can also affect the degree to which the colorant affects the polymer. To effectively apply colorants in injection molding, a useful tip is to have good control over the amount of colorant added. Typically, adding 1-2% of colorant to a resin is completely harmless. The exact percentage of colorant to be used will also need to be recommended by a professional industrial designer.
