Abstract

A polyolefin composition includes a polyolefin substrate having incorporated therein a nucleating agent and a filler, wherein the composition exhibits an impact strength of >35 in-lb measured according to ASTM D4226, and a coefficient of linear thermal expansion of <4.5×10E-05 in/in/ft measured according to ASTM D696. The polyolefin composition may further include one or more of an ultraviolet light absorber, a hindered amine light stabilizer, an antioxidant, a colorant, a flame retardant, and an antimicrobial compound. The polyolefin compositions may be useful for construction articles for outdoor use, for instance house siding, cladding, soffit or roofing.
