Kalrez is chemical-proof synthetic rubber. It maintains the properties of rubber even at high temperatures. The key strengths of Kalrez are that it has both the elasticity and seal characteristics of an elastomer and the chemical resistance and thermal stability of Teflon. Kalrez produces a small amount of gas in a vacuum and exhibits high…
ACTISEAL is a static elastic metallic seal. It has properties that conventional gaskets, metal O rings, or rubber O rings do not have. With its special structural design, the elastic metallic gasket has low-load characteristics and capabilities to follow deformation, which conventional gaskets and metallic O rings do not have. For more information of the…
A brush seal includes bristles and two plates, and ensures highly-efficient airtightness. When mounted in an engine, the brush seal keeps up with changes in clearance between the stator and rotor and in eccentricity. With the excellent airtightness, the brush seal significantly improves the power and fuel efficiency of the engine. Brush seals have been…
A segment seal is a gas seal primarily for use in the main shaft of an aircraft engine. Since it has high reliability, the segment seal is also used in rockets. The segment seal has been developed mainly for the main shaft of an aircraft engine, with technical support provided by Koppers Inc., U.S. This…
