Aurora Plastics offers an exceptionally strong and durable line of compounds for siding applications. Our exterior weatherable RPVC compounds meet AAMA (American Architectural Manufacturers Association) standards for outdoor performance and are highly impact resistant. These compounds are available in powder or pellet form in various colors. We also offer PVC/acrylic alloy capstock compounds that combine the easy processability of rigid PVC and the superior weatherability of acrylic. These highly weatherable, pelletized capstock compounds are ideal for darker colors and can be applied thinner than standard PVC capstocks. Thinner capstock requires less material, making our PVC/acrylic capstock a high-performance, economical solution for siding applications.
