Flame retardant compounds and masterbatches are additives incorporated into plastics to reduce flammability and slow fire spread. Widely used in industries like aerospace, automotive, construction, and electronics, they are essential for products exposed to high temperatures or near ignition sources. These materials typically consist of chemical combinations—either brominated or non-halogen-based—that work together to inhibit fire propagation. The choice of flame retardant depends on factors such as the polymer type, intended application, and required flame retardancy level. To ensure efficacy and safety, these compounds and masterbatches must comply with strict regulatory standards and pass rigorous tests, such as the UL 94 test, which evaluates the flame retardancy of plastics.
