3:1 Single Wall Flame Retardant Heat Shrink Tubing (Item FR140, Black)
ApplicationThe 3:1 single wall flame retardant heat shrink tubing is made by extruding the polyolefin after radiation disposal and has uniform wall thickness, the thickest layer reaching to 3.7mm.
This tubing not only has excellent electrical insulation property but also has good flame retardant properties and is mainly applied for insulation protection of medium or low voltage cables with flame retardant requirements or for anti-corrosion and mechanical protection used of any pipe.
