<p>Extruding thermoplastic rubber into a thin film employing as the thermoplastic rubber a mixture of thermoplastic rubber and sufficient amorphous polypropylene to improve the processability of the thermoplastic rubber as evidenced by the ability to achieve a draw ratio while extruding the mixture of at least 1. The films and products formed therefrom retain characteristic elastomeric properties of pure rubber, but are significantly more processable owing to the presence of amorphous polypropylene.</p> |
