COMPOSITE BOARD INCLUDING CORE AND CAPSTOCK, AND ASSOCIATED METHOD
A composite board includes a core and a capstock positioned to at least partially cover the core, where the capstock includes (a) a thermoplastic elastomer, where the thermoplastic elastomer does not include thermoplastic polyurethane (TPU), and (b) a blend of thermoplastic matrix polymers, where the blend thermoplastic matrix polymers includes, based on a total weight of the capstock, 10 wt. % to 70 wt. % polyvinyl chloride (PVC), 1 wt. % to 60 wt. % acrylonitrile-styrene-acrylate (ASA), and 1 wt. % to 60 wt. % styrene-acrylonitrile (SAN).
