flame retardant cables formed from halogen-free and heavy metal-free compositions

摘要

flame retardant compositions are disclosed, which include a base polymer, a flame retardant filler and a flame retardant synergist. flame retardant compositions are halogen-free and free from heavy metals and can be cross-linked to form a cable insulation layer or cable jacket. the cables can pass the ul vw-1 flame test. sheathed cables formed from such flame retardant compositions are also described herein.
