Choosing the right color masterbatch can increase the color of the product plastic. The carrier resin is preferably the same resin as the resin to be blended to obtain good compatibility.
That is an exception for us: a similarly similar carrier resin can be used if it does not adversely affect the final product. For example, polyethylene carrier resins are sometimes used in polypropylene.
A good example of use is that it is desirable that the melt flowability of the carrier resin is relatively high so that it still has the same or higher melt fluidity as the blended resin after carrying the pigment.
