Flame Retardancy in Halogen-Free Cables
Halogen-free cables are a required staple in a vast number of industrial and infrastructural applications. Over time, different labels for these cables have been established, such as FRNC, HFFR, LS0H, or LSZH. But how meaningful are these abbreviations, and what are the benefits of halogen-free cables compared to products containing halogens? Halogens (which means “to form salt”) include the chemical elements chlorine (Cl), bromine (Br), fluorine (F), and iodine (I). When manufacturing cables, these are used to make certain conductor insulation and jacketing materials flame retardant.
