How to stop cast filled acrylic sheet from warping and bowing after it has been polymerized?The acrylic sheet is filled with inert mineral fillers...

To reducing warping, you can add a moisture-resisting material which has an acrylic substrate and from a group of PVDF homopolymers and copolymers etc, to form a low moisture absorbing multi-layer object, and thus preventing warping from happening.
