    摘要: Extruded synthetic resinous thermoplastic foams of increased cell size are obtained when using volatile fluid blowing agents by incorporating a cell-size enlarging agent into the extruded composition, the cell-size enlarging agent being liquid at the foaming temperature and generally soluble in the heat-plastified foamable mixture.
