HFFR Cable Compounds
HFFR cable is the short form of Halogen Free Flame Retardant cable. Unlike the PVC cable, the materials used in HFFR cable insulation and sheath have been produced as a material that does not conduct flame and poison for a certain time during fire incidents, thus people trapped in fire can have better chances for their rescue. HFFR materials are produced by compounding EVA, PP and PE polymers with ATH (aluminum trihydroxide) or MDH (magnesium hydroxide) in a proportional ratio. HFFR cables are now widely used in indoor buildings, such as airport, subway, hospital, school, shopping mall, office building, and etc.
