Abstract: A supported elastomeric foam (100) includes an elastomeric matrix (102) formed of an elastomer and including a reinforcement region (104) and a foamed region (106). The foamed region includes gas filled cells (108) in the elastomer, and the reinforcement region includes a porous layer (204) having an interconnected network of pores at least partially imbibed with the elastomer. The foam can include an adhesive at a surface of the foam. A compressible seal (802) including a compressible body, which can be elastomeric foam, can also include a pattern of discontinuous adhesive regions about which the compressible body can deform to form a sea. The supported elastomeric foam can form a gas tight seal in an interface when placed under minimal compression.

Abstract: A compressible seal (400A) includes a compressible body (406) having a first surface (410) and a second surface. A pattern of discontinuous adhesive regions (412) is formed of an adhesive connected with at least one of the first surface (410) or the second surface of the compressible body (406). The compressible body (406) is operable to conform around the pattern of adhesive regions (412) to prevent fluid ingress when the compressible body (406) is compressed.

Abstract: A sealant made of expanded polytetrafluoroethylene having a coating of an active hydraulic fluid repellent component and an indicator, the sealant having a first uncompressed state and a second compressed state, wherein the sealant is repellent to hydraulic fluid in both the first uncompressed state and the second compressed state.

Abstract: The functioning of an aircraft is dependent on numerous mechanical, hydraulic and electronic systems. Access to these systems, for example for maintenance purposes, can often only be made from the outside or inside of the aircraft by removing panels. In order to protect the systems from environmental influences such as water ingress, a reliable panel sealant is required. A sealant material has been developed which before use consists essentially of a) 30-90% by weight porous base material and b) 10-70% by weight corrosion inhibitor having the requirements that it is compatible with saud porous material and has a group which is polar in nature. Preferably the porous base material is expanded polytetrafluorethylene.
