Halogen-free cable is intended for use in applications in which insulation with low toxicity, low smoke generation, and low corrosiveness is needed.
In response to increased health concerns regarding halogenated products, halogen-free cables provide a high-performing, clean, safe alternative.
What makes halogen-free cables safer? They don’t contain the reactive elements of the halogen family, such as chlorine and fluorine, which create toxic, corrosive fumes when burned. These fumes form an acid when mixed with water, including moisture found in lungs and eyes.
Since the smoke caused by burning halogenated products is so dangerous, governments are now moving to introduce stricter halogen cable regulations. In response, more and more manufacturers are switching to halogen-free options.
Halogen-free cables emit drastically lower levels of carbon monoxide - sometimes as much as 360% less carbon output! Halogen-free cables also produce fewer of the air-borne particles which are the makeup of smoke.
These cables are great for all types of applications, including shipbuilding, in industrial plants, and in any heavily-populated location, such as a mall or airport.
Halogens are non-metallic elements found in the periodic table. The five halogens are fluorine, chlorine, bromine, iodine, & astatine
