This invention relates to plasticized poly(vinyl chloride) compounds formulated to provide sufficient flexibility and flame retardance to be suitable for building and construction polymeric articles. One aspect of the present invention is a flame retardant poly(vinyl chloride) compound, comprising a mixture of: poly(vinyl chloride); a plasticizer selected from the group consisting of polymeric plasticizer, alkyl aryl fire retardant plasticizer, and combinations thereof; and optionally functional additives, wherein the mixture has i) a Limiting Oxygen Index of greater than 50% according to ASTM D2863; ii) an Elongation at Break of at least 10% according to ASTM D638 (Type IV); and iii) a Modulus of Elasticity of less than about 15,000 psi according to ASTM 638 (Type IV). |
