Abstract
This invention relates to moldable or extrudable type elastomeric compositions having a viscosity at 200.degree. C at 0.73 sec.sup.-1 of about less than about 10.sup.5 poise. The compositions used for elastomeric articles include 100 parts of a neutralized sulfonated EPDM terpolymer; about 25 to about 150 parts per hundred of a non-polar process oil; about 25 to about 200 parts per hundred of a filler; and about 2 to about 50 parts of a hydroxyalkyl carboxylate ester. These blend compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment into elastomeric articles having excellent physical properties and desirable rubbery characteristics.
