Glow Wire Test and Its Importance in Evaluating Flame-Retardant Polyamide and Polypropylene Compounds

Safety in the use of electrical and electronic devices particularly in the power and electronics industry, lighting systems, and household appliances—is of critical importance. One of the key factors influencing the safety of these products is the flammability behavior of the polymeric materials and engineering compounds used in their construction. Many electrical components are manufactured from polymers such as polyamide (PA), polypropylene (PP), acrylonitrile butadiene styrene (ABS), and polycarbonate/acrylonitrile butadiene styrene (PC/ABS), each of which exhibits different thermal and fire behavior depending on its chemical structure. Therefore, selecting materials with controlled thermal resistance and flammability is one of the fundamental requirements for safe product design.
