Low smoke halogen-free flame retardant polyolefin cable material is usually composed of polyolefin blend resin, flame retardant filler aluminium hydroxide, magnesium hydroxide and some appropriate antioxidants added to improve the thermal life. Someti...
For halogen-free low smoke flame retardant sheath, the tensile strength and elongation at break decreased seriously after immersion....
Common PVC flame-retardant cable material contains a lot of halogen, which will produce a lot of smoke and poisonous corrosive hydrogen halide gas when burning. Halogen-free flame-retardant is mainly realized in polyolefin, so low-smoke halogen-free c...
