Product description Lucofin® 7440 HFFR is a thermoplastic, halogen free flame retardant and low smoke compound for the insulation and/or sheating of cables. Lucofin® 7440 HFFR combines good extrusion properties with flame retardancy. The properties of Lucofin® 7440 HFFR are in compliance with VDE 0207 part 24(HM 2/4), VDE 0207 part 23 (HJ2), BS 6724 as well as other power and telecom standards. Applications and markets Target markets include -among others- power and telecom cables as well as construction and optical fiber cables. Lucofin® 7440 HFFR is designed in order to avoid both smoke and corrosive gases in case of a fire. Cables in trains, ships, tunnels, office buildings, public houses and off-shore installations are only some examples. Due to its low water absorption, excellent low temperature properties and good ageing resistance Lucofin® 7440 HFFR is specifically suited for the following applications: Cables in wet areas
Cables in cold areas
Cables in hot areas
