Hapco manufactures many polyurethanes, epoxies, and dispensing machines that are used by the offshore industry. For decades, Hapco’s Hapflex™ and Di-Pak™ materials have been used to mold seals, deep water flowline coatings, and a wide array of components on manned and unmanned underwater vehicles.

Hydrophpobic elastomers, such as our Di-Pak™ 4888, have been used to pot and encapsulate electronic devices that will be submersed in seawater. These components can spend several years underwater, either continuously or intermittently, and the material selected must retain its mechanical properties.
