ABSTRACT:
This invention discloses a rubber composition that has a high capacity for absorbing energy. This rubber composition has a Shore A hardness in the range of about 20 to about 30 and is nontoxic. Thus, it has excellent properties for use in articles that come in close proximity to humans or animals which benefit from the ability to absorb energy, such as shoe soles, gun butt pads, baseball glove insert pads, helmet liners, hammer handles, horse shoe pads, tumbling mats, and the like. The energy absorbing rubber composition of this invention comprises a mixture of a polynorbornene rubber, a plasticizer, and a resin which is incompatible with the polynorbornene.
