Abstract:
The present invention provides shaped articles comprising one or more composite layer of (i) a vulcanizate encapsulated in a colored or uncolored thermoplastic polymer matrix containing one or more passivating agent, and (ii) a reflective material chosen from colored fluidizable particles of a thermoplastic reflective colorant encapsulated vulcanizate, roofing granules, thermoplastic encapsulated roofing granules, the colored thermoplastic polymer matrix, and combinations thereof. The articles can be laminates of colored or reflective layers on uncolored or other layers, or one or more colored layer having colored fluidizable particles are dispersed within the surface of the uppermost composite layer or having either the colored fluidizable particles or the granules are dispersed on the surface of the composite layer or are adhered thereto with a thermoplastic resin. Roofing shingles are provided.
