Working with color concentrates? Here is everything you need to know!

The different industries such as medical industry, construction industries etc consider color as one of the important element for marketing and sales. However, if we talk about the different plastic industries, it is very important for them to have deep knowledge about the different implication of colors for their business.

Are you thinking of working with color concentrate? Well, here are some of things that you need to know-
  • One of the most important things is that it is very important to use the right concentrates at the very beginning of the product development cycle to avoid any kind of problem that may arise in the future if proper planning is not done.
  • The mixture of all the different ingredients that is used to make a colorant includes 30% to 50% of a pelletized concentrate. The remaining is known as carrier resin that acts as a binder for the colorant
  • There are typically two methods of adding these concentrates. The first method is to add the base color in a liquid carrier whereas the second method involves breaking down of the pigments into fine particles after which the color is dispersed into the liquid carrier.
  • The concentrates that you need to add to the base resin are usually at levels of 2-5 lb per 100 lb to the natural material.
  • It is very important for a carrier resin to chemically match the base resin. The easiest way for this is to make the concentrate from exact type of polymer as the base resin.
  • Molecular weight of the carrier is another important component that should not be ignored. The molecular weight is usually expressed in terms of Melt Flow Rate (MFR). In addition, for a good mixing, a carrier with high Melt Flow Rate is preferred than the base resin.
  • However, if the Melt Flow Rate of the carrier resin is high, it means that the final product will show some signs of reduced performance in the final result.
There are number of benefits of using these concentrates therefore, if you are thinking of working with the concentrates, do not forget to consider the aforementioned things.
