PVC foam board is a particularly light material. It is approximately 50% lighter than solid PVC sheets. The solid version is more rigid and retains its shape. The application and desired machinability determine which type of PVC suits your project. White foamed PVC is very suitable for advertising purposes. We recommend solid PVC for applications in mechanical engineering or electrical engineering.
