PROPYLENE-BASED RESIN EXTRUDED FOAM

Title:

PROPYLENE-BASED RESIN EXTRUDED FOAM

Document Type and Number:

Japanese Patent JPH11152361

Kind Code:

A

Abstract:

To provide a propylene-based resin extruded sheet foam which can solve drawbacks of conventional propylene-based resin extruded foams using a noncrosslinked propylene-based resin as a substrate resin, is free from surface irregularities and substantial free from open cell, and, in its entirety, has homogeneous and excellent properties.

This propylene-based resin extruded foam is an extruded sheet foam comprising a noncrosslinked propylene-based resin as a substrate, wherein the propylene-based resin as the substrate resin has a melt tension of not less than 7 gf at 230°C and a semicrystallization time of not less than 800 sec at a temp. of crystallization temp. +15°C and the sheet foam has a density of 0.10 to 0.25 g/cm3 and a number of surface cells of 26 to 48 cells/9 mm2.
