IMPROVED HIGH TEMPERATURE MECHANICAL PROPERTIES OF ELASTOMERS WITH SEMI-CRYSTALLINE POLYMERS FOR DOWNHOLE APPLICATIONS

摘要

Compositions and methods for improving the mechanical properties of elastomers for downhole sealing applications are provided. An embodiment is a composition comprising: a base elastomer; a curative agent; and a semi-crystalline polymer. Another embodiment is a tool comprising: at least one component comprising a vulcanized elastomer, wherein the vulcanized elastomer comprises a base elastomer, a curative agent, and a semi-crystalline polymer. Another embodiment is a method comprising: blending a base elastomer, a curative agent, and a semi-crystalline polymer to form a mixture; placing the mixture in a mold; and vulcanizing the mixture.
