TE Connectivity's (TE) Raychem FCSM thick wall, flame retardant tubing is used for insulation purposes and as mechanical protection on low voltage cable accessories, including for jointing cables in mining, power plants, construction and transportation industries, railway and rolling stock applications and for many other operational purposes, where flame retardancy and flexibility are required. FCSM heat shrinkable tubing is produced from a material, combining flame- retardant characteristics with mechanical flexibility and abrasion resistance. This combination of features has led FCSM tubing to be used in a wide range of demanding applications, in particular to insulate, to protect and to seal flexible cables and cable accessories. The FCSM tubings are applicable on the most substrate materials, as standard poly or elastomeric insulated or jacketed cables or lead-jacketed cables, which may also include aluminum or steel armoring. The material of the FCSM tubings is stabilized against UV irradiation.
