Polystyrene resin foam sheet and method for producing the same |
| abstract |
PROBLEM TO BE SOLVED: To provide a polystyrene resin foam sheet having a shortened aging period and having uniform secondary foamability in the width direction, and a method for producing the same. A foamed polystyrene resin sheet is obtained by extrusion-molding a polystyrene resin together with a foaming agent, and is formed such that an end in a width direction is thicker than an average thickness in a width direction. This polystyrene-based resin foam sheet is then wound into a roll and aged. |
