PROBLEM TO BE SOLVED: To provide a rubber foam which is equivalent in density to a conventional urethane, polyethylene, or like foam and being excellent in weathering resistance and heat resistance and lower in density than a conventional rubber foam by using a normal pressure foaming method without using any special foaming equipment and to provide its production method. SOLUTION: The rubber foam is a rubber foam which is obtained by blending at least a rubber component and an olefin resin in a specified blend ratio and foaming the blend by a normal pressure foaming method simple in equipment and is lower in density than a conventional rubber foam, good in sound-absorbing characteristics, and possible in cost reduction and development in the field of resin foams such as urethane and polyethylene foams. Its production method is also provided. COPYRIGHT: (C)2009,JPO&INPIT |
