Flame retardant masterbatch is a plastic colorant which is well dispersed by a high proportion of pigments or additives and thermoplastic resin. The selected resin has good wetting and dispersion effect on the colorant, and has good compatibility with the colored material. Flame retardant masterbatch has the following advantages:

　　1. Coloring and product processing are completed at one time to avoid the heating process of plastic caused by granulation coloring, which is good for protecting the quality of plastic products.

　　2. The use of flame retardant masterbatch for coloring can simplify the production process of plastic products.

　　3. The coloring of flame retardant masterbatch can save a lot of electric energy.
