With the advancement of technology and the improvement of living standards, polymer materials such as plastics and rubber are becoming increasingly important in people's lives, and their applications are showing a trend of expanding year by year. However, most organic polymer materials have varying degrees of flammability in the air. In order to achieve their applications in various industries such as military, aerospace, transportation, power, and civilian use, flame retardant modification has become a new topic. The ideal flame retardant modification method is often to improve the fire resistance of plastics by adding flame retardants or flame retardant masterbatch products.

　　Flame retardant masterbatch is one of the most excellent flame retardant products in plastics, rubber and other resins today. Flame retardant masterbatch (masterbatch) is a granular product made by organic combination, modification and synergistic effect of various flame retardant components on the basis of flame retardants, and through mixing, extrusion and granulation by twin-screw or triple screw extruders.

　　Unlike flame retardants, flame retardant masterbatch has many advantages such as easy addition to resins, cleanliness and hygiene, high flame retardant efficiency, small amount of addition, minimal impact on the mechanical properties of resins, less occurrence of adverse phenomena such as delamination, patterns, and precipitation after addition, and saving labor, material costs, and time.

　　Generally speaking, the dispersibility, flowability, compatibility with resin, thermal stability, and weather resistance of flame retardant masterbatch in resin are much better than those of ordinary flame retardants. In addition, the flame retardant efficiency and effectiveness (cost-effectiveness) of properly formulated flame retardant masterbatch are also much better than those of ordinary flame retardants. So flame retardant masterbatch has become one of the best choices for achieving fire resistance requirements in flame retardant plastic products, and has become an effective substitute for flame retardant powders.

　　Easy to use: Flame retardant masterbatch is mostly pill sized particles, which are exactly the same size as ordinary plastic particles, improving their compatibility, making them easier to disperse and add, and also hygienic and reducing volatilization waste.

　　Good compatibility with resin: Generally, flame-retardant masterbatch undergoes special treatment to improve its compatibility with plastic resin, making it less prone to delamination, frosting, patterns, and other issues even when added in large amounts to the resin.

　　Reducing costs and increasing product added value: The addition of flame-retardant masterbatch often makes general plastics meet or approach the application requirements of engineering plastics, increasing product added value and reducing raw material costs.
