PREFORMED COMPOSITIONS IN SHAPED FORM COMPRISING POLYMER BLENDS

摘要

Preformed compositions in shaped form comprising polymer blends, and the use of these preformed compositions in shaped form to seal apertures are disclosed. In certain embodiments, the preformed compositions are electrically conductive and are capable of shielding EMI/RFI radiation. The polymer blend includes a polysulfide component and a polythioether component.
