ABSTRACT:
The present invention relates to a medium density chlorinated polyvinyl chloride foam and the method of preparing such a foam using a blend of chemical blowing agents. The foam having a specific gravity in the range of about 0.3 to about 1.5 comprises chlorinated polyvinyl chloride, a blend of decomposition type blowing agents, a tin stabilizer, an optional impact modifier and an optional high molecular weight process aid.
