Masterbatch is used in place of fully colored compounded materials largely referred to as pre-color. This option can be more expensive due to volume minimums, inventory requirements and the threat of obsolescence whereas masterbatch mitigates these challenges. The ability to dose the masterbatch with absolute precision is a perfect complement for injection molding and extrusion customers looking to reduce their operating costs. Even after being convinced that masterbatch is a better colorant option, many processors still debate whether liquid or pellet form is the better option? Both have advantages and disadvantages. The one historical advantage liquid has enjoyed over pellet masterbatch has been rooted in economics. That stated, there is new pellet technology that has come on the scene in the last few y...
