Abstract
A flame-retardant compound is disclosed, comprising a polyolefin alloy and a combination of frame-retardant agents. The polyolefin alloy comprises at least one polyolefin and a metallocene-catalyzed olefin copolymer. The flame-retardant agents comprise a nanoclay and at least one inorganic flame-retardant. An essentially halogen-free flame-retardant compound is preferred. Surface coverings for mammalian-occupied spaces benefit from the properties of the flame-retardant compound.
