Abstract:
Foam compositions are provided including a polylactic acid polymer; second (e.g., polyvinyl acetate) polymer having a glass transition temperature (Tg) of at least 25° C.; and plasticizer. Also described are articles comprising the foam compositions, such as a sheet or hearing protection article. Methods of making and using the foam compositions are further described herein.
