Halogen-free materials are substances that do not contain halogens, which are a group of elements including fluorine, chlorine, bromine, iodine, and astatine. These materials are often used in various applications, such as electronics and construction, because they are considered safer for the environment and human health. When burned, halogen-containing materials can release toxic gases, while halogen-free alternatives tend to produce less harmful emissions. The use of halogen-free materials is becoming increasingly popular due to stricter regulations and growing awareness of sustainability. Many manufacturers are now opting for these materials to meet environmental standards and to appeal to consumers who prioritize eco-friendly products. This shift supports the development of safer and more sustainable technologies.
