GSmach has delivered more than 1000 sets of high performance extruder machines for color masterbatch. We would like to share the experience for the following special applications. Color masterbatch compounding is one of the main applications for twin screw extruder. Color masterbatch is used for any polymer and all kinds of products. There are three types of Color Masterbatch:1) Mono color masterbatch or SPC (single pigment concentrate): polymer compounding with one single pigment and mostly without the wax and additive2) Tailor-Made masterbatch or Custom coloring: mixing different Mono color masterbatch pellets to get the color the customer wants3) Customized masterbatch: mix polymer and several pigment and additives
