RESIN COMPOSITION FOR POLYOLEFIN RESIN FOAM, POLYOLEFIN RESIN FOAM AND FOAMED SEALING MATERIAL

摘要

The present invention relates to a resin composition for a polyolefin resin foam, including: a polyolefin (A) having a melt flow rate (MFR) at a temperature of 230° C. of 0.2 to 0.7 g/10 min and a melt tension at break measured at a temperature of 190° C. of 30 cN or more; and a polyolefin (B) having a melt flow rate (MFR) at a temperature of 230° C. of 1.5 to 10 g/10 min and a melt tension at break measured at a temperature of 190° C. of 10 cN or more, in which the polyolefin (B) is contained in an amount of from 15 to 75 parts by weight based on 100 parts by weight of the polyolefin (A).
