Title:
ELASTOMER COMPOSITION FOR FOAM MOLDING AND FOAM MOLDED BODY
Document Type and Number:
Japanese Patent JP2017088748
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an elastomer composition for foam molding excellent in foam moldability and excellent in flexibility as well as abrasion resistance and scratch resistance of a molded article and a foam molded body obtained by using the composition.SOLUTION: There is provided an elastomer composition for foam molding containing a hydrogenated styrene block copolymer A, a polypropylene resin B and a foaming agent C, wherein the hydrogenated styrene block copolymer A is a hydrogenated additive of a block copolymer A' consisting of a styrene carbohydrate polymer block a and a conjugated diene compound block b, has weight average molecular weight of 50,000 to 200,000, apparent viscosity at temperature of 180°C and shear rate of 121.6/s of 500 to 4300 Pa s and the polypropylene resin B has meld mast flow rate at temperature of 230°C and load of 21.2 N of 0.1 to 100 g/10 min. and a foam molded body obtained by using the composition.SELECTED DRAWING: None
