POLYPROPYLENE-BASED RESIN FOAMED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a foamed sheet having a beautiful appearance and a high closed cell fraction and suitably formable to various molded products. SOLUTION: This foamed sheet is characterized by comprising a polypropylene-based resin having an elongation viscosity steeply increasing accompanying to increase of a deformation amount in a molten state and <1.2×10-3Pa-1 an equilibrium compliance (Je0) measured at 210 deg.C, and 50-500 kg/m3 density, >=60% closed cell fraction and 0.8-8 mm thickness.
