Abstract
A swellable composition comprises: a matrix material; and a condensed expandable graphite material disposed in the matrix material. A seal arrangement comprises: a swellable member and a sealing member disposed on a surface of the swellable member; wherein the swellable member comprises a condensed expandable graphite material. The condensed expandable graphite material in the swellable composition and the swellable member has a bulk density of about 1 to about 8 g/cm3 and comprises expandable graphite.
Claims35
A swellable composition comprising:
- a matrix material;
- and
- a condensed expandable graphite material disposed in the matrix material;
- wherein the condensed expandable graphite material has a bulk density of about 1 to about 8 g/cm3 and comprises expandable graphite.
A seal arrangement comprising:
- a swellable member and a sealing member disposed on a surface of the swellable member;
- wherein the swellable member comprises a condensed expandable graphite material;
- and wherein the condensed expandable graphite material has a bulk density of about 1 to about 8 g/cm3 and comprises expandable graphite.
A method of deploying a seal arrangement, the method comprising:
- positioning a seal arrangement at a predetermined location;
- the swellable member having a first shape;
- and
- activating the swellable member to cause the swellable member to attain a second shape different from the first shape,
- the seal arrangement comprising:
- a swellable member and a sealing member disposed on a surface of the swellable member;
- wherein the swellable member comprises a condensed expandable graphite material, and wherein the condensed expandable graphite material has a bulk density of about 1 to about 8 g/cm3 and comprises expandable graphite.
