A profile extruded article includes a composition that is formed by melt-kneading particular amounts of a poly(arylene ether), a polystyrene-poly(ethylene-butylene)-polystyrene triblock copolymer, a homopolystyrene, and a polysalicylate. The article is particularly useful in the fabrication of solar collectors for low cost solar energy systems.
