Abstract:
The present invention provides an elastomer composition comprising a mixture (a) of a hydrogenated block copolymer (a-1) and a hydrogenated block copolymer (a-2); a polypropylene resin (b); and a hydrocarbon oil (c). The hydrogenated block copolymer (a-1) has a specific structure, a specified number average molecular weight and a specified block content. The hydrogenated block copolymer (a-2) has a specific structure, a specified number average molecular weight, a specified block content, a specified vinyl bond content before hydrogenation and a specified MFR. The polypropylene resin (b) has a specified MFR. The present invention also provides a storage cover of airbag devices which is made of the elastomer composition.
