Ensinger TECASINT 4021 Polyimide, Black, 15% Graphite (PI)

TECASINT is a range of non-melting high temperature polyimides characterized by high strength over a wide range of temperatures, good long term thermal stability, minimal thermal expansion and excellent wear resistance among other things. The TECASINT 2000 series offers these enhanced thermal properties along with lower moisture absorption, a higher degree of toughness, and better machining properties. TECASINT 2011 is unfilled, while TECASINT 2021 contains 15% graphite which offer improved wear resistance and a lower coefficient of friction. TECASINT 2000 series with their superior physical properties, are ideal for application in the aerospace, nuclear, automotive, electrical/electronics, and chemical processing industries.Main features: Very high temperature and oxidative resistance, high creep resistant, good radiation-resistance, good sliding properties, very high chemical resistance, very low absorption of water, flame retardant according to UL94 V-0, not electrically insulating, easily machined, sensitive to hydrolysis in higher thermal rangeApplications: Mechanical engineering, automotive engineering, conveyor technology, hot glass technology, precision engineeringPreferred Fields: Valve seats, friction rings, skid rails, chain guides, piston rings, gripper for hot glass, washers, bearingsInformation Provided by Ensinger Sintimid
