Lucofin® 7440 HFFR

About
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 Ships and marine Outdoor Channels Off-shore Cables in cold areas Regions with harsh winters Refrigerated rooms Outdoor Snowy/icy conditions Cables in hot areas Regions with long summers Outdoor Areas at elevated temperatures Long life time required Packaging Granules in 25 kg bags&&
