ACRYLIC RESIN FOAM AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an acrylic resin foam that has excellent heat resistance and lightness in weight, can prevent elongation of production time, and further prevents volumetric change due to heat.SOLUTION: An acrylic resin foam comprises an acrylic resin and plasticizer. The acrylic resin comprises maleic acid anhydride and methacrylamide as constitutional units. The acrylic resin foam has an average bubble diameter of 0.7 mm or less and an open cell ratio of 15% or less.
