RESIN COMPOSITION CAPABLE OF PROVIDING POLYOLEFIN-BASED RESIN FOAM WITH EXCELLENT FLEXIBILITY INCLUDING UNIFORM MICRO CELLS, A POLYOLEFIN-BASED RESIN FOAM, AND A FOAMING SEALANT

摘要

PURPOSE: A resin composition for polyolefin-based resin foam is provided to form a polyolefin-based resin foam with excellent flexibility including uniform micro cells when the discharging rate is fast.;CONSTITUTION: A resin composition for polyolefin-based resin foam comprises: polyolefin(A) which has a melt flux of 0.2-0.7 g/10minutes at 230 deg. C, and a melt tension of 30 cN or more at fracture measured at 190 deg. C; and polyolefin(B) which has a melt flux of 1.5-10 g/10minutes at 230 deg. C, and a melt tension of 10 cN or more at fracture measured at 190 deg. C. The amount of the polyolefin(B) is 15-75 parts by weight based on 100.0 parts by weight of the polyolefin(A).;COPYRIGHT KIPO 2013
