[0002] Flame retardant masterbatch is a granular substance made by combining flame retardants and carrier resins through a specific process. It can be easily added to the production process of plastic products to improve their flame retardant properties. The use of flame retardant masterbatch not only simplifies the production process but also improves the dispersibility of flame retardants in the matrix material, thereby enhancing the quality and consistency of the final product.

[0003] The premixed material is fed into a twin-screw extruder. In the extruder, the material is heated, melted, sheared and mixed, and then extruded into strips from the die. After cooling and drying, the extruded strips are cut into granules, which are flame retardant masterbatches.
