Due to its highly flammable nature, polymer materials pose significant safety risks and limit their use in most industrial applications, such as automotive, electronics, and electrical. To address these risks, flame-retardant properties have been incorporated into polymer materials. A standard method for assessing a material's fire resistance is the glow-wire test, approved by the IEC. This test is a key evaluation of fire safety and is frequently used to determine how materials used in electrical appliances respond to fire. This study examines the method used to blend flame retardants with polymer materials and presents the characteristics of the GWFI and GWIT test results on these materials. The results discuss various material-forming processes that integrate these additives into polymers, including extrusion and injection molding. The glow-wire test results showed a characteristic, namely the occurrence of intumescence, as indicated by the burnt test results, especially around the point of contact with the glowing wire. © 2026 The Authors.
