Flame retardant masterbatch (bromide/halogen), also known as flame retardant masterbatch is in plastic and rubber resin performance in one of the most excellent flame retardant products, flame retardant masterbatch (masterbatch) is on the basis of the flame retardant treated with the combination of many kinds of flame retardant ingredients, modification and association effect, and through the double screw or triple screw extruder through mixing, extruding and granulating and made a granular product. Unlike flame retardant, flame retardant masterbatch in resin is easy to add, clean sanitation, fire retardant efficiency is high, add a little, little influence on mechanical properties of the resin, not easy to happen after adding layered, decorative pattern, as well as the precipitation phenomenon, save manpower and material resources cost and time, and many other advantages. In general flame retardant masterbatch on the dispersion of the resin, liquidity, and the compatibility of resin and thermal stability and weather resistance are much better than common flame retardants, and formula of flame retardant masterbatch its efficiency and effectiveness of flame retardant (price) is far superior to ordinary flame retardant. So the flame retardant masterbatch as flame retardant plastic products achieve one of the best choice of fire prevention requirements, and an effective alternative to flame retardant powder,.
