Halogenfria

Halogenfria refers to materials that do not contain halogens, which are elements belonging to Group 17 of the periodic table: fluorine, chlorine, bromine, iodine, and astatine. In the context of materials science and electrical engineering, "halogenfria" most commonly applies to cables, circuit boards, and other electronic components. The absence of halogens is a key characteristic sought after for safety and environmental reasons.

Traditional materials used in electrical insulation, such as PVC (polyvinyl chloride), contain halogens. When these materials burn, they can release toxic and corrosive gases like hydrogen chloride or hydrogen bromide. These gases are hazardous to human health and can also damage electronic equipment. In contrast, halogen-free materials, when subjected to fire, produce significantly less smoke and emit fewer toxic fumes. This improved fire safety performance is crucial in environments where evacuation and damage limitation are paramount, such as public buildings, transportation systems, and data centers.

Beyond fire safety, the environmental aspect is also a significant driver for the adoption of halogen-free materials. The production and disposal of halogenated compounds can raise environmental concerns. Halogen-free alternatives are often considered more environmentally friendly throughout their lifecycle. The trend towards halogen-free components reflects a growing awareness and regulatory push for safer and more sustainable materials in various industries.
