Abstract

Foamed acrylic materials using both traditional chemical blowing agents as well as foamable microspheres. The acrylic foams have improved density reduction, optical properties, and insulation properties. The acrylic foams can be formed by traditional melt processing methods (extrusion, blow molding, etc.) as well as innovative foaming methods, such as foaming during or after polymerization. One method involves the use of expandable microspheres blended with monomers, the monomers then polymerized through bulk polymerization in cell cast, infusion, or compression molding processes. This method can be effectively used to produce composite foam structures.
