FLAME RETARDANT CROSSLINKED RESIN FOAM

摘要

PROBLEM TO BE SOLVED: To provide a flame retardant crosslinked foam having both high flexibility and good heat-resistance as well as flame retardance. SOLUTION: The flame retardant crosslinked foam is a crosslinked foam obtained by crosslinking and expanding a resin composition which includes 3-180 pts.wt. hydrogenatedα-olefin/butadiene copolymer obtained by hydrogenating a copolymer of anα-olefin and butadiene to 100 pts.wt. resin matrix component consisting of≥55 wt.% polypropylene-based resin and≤45 wt.% polyethylene-based resin and a flame retardant and has a 25% compressive hardness of not more than a compressive hardness index value. The compressive hardness index is defined as compressive hardness index=3.1×(apparent density(kg/m3))-73. COPYRIGHT: (C)2005,JPO&NCIPI
