Document Type and Number:
Japanese Patent JP3277148
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a uniform cellular material, capable of easily controlling a temperature at an extrusion blowing, etc.
SOLUTION: This propylene-based resin cellular material is obtained by melting and mixing a mixed powdery material containing a polyfluoroethylene consisting of polytetrafluoroethylene particles having ≤10 μm particle diameter and organic polymer particles, a polypropylene-based resin and a blowing agent in an extruder, and extruding through dies mounted at the tip of the extruder for blowing under a low pressure.
