gasketen

Gasketen is a term used to describe a family of gasket materials employed to form mechanical seals between joined surfaces. These elastomeric materials are intended to deform under compression to fill irregularities and prevent leakage of liquids or gases.

Gasketen encompasses a range of polymers, including nitrile (NBR), ethylene propylene diene monomer (EPDM), silicone, fluorosilicone, and fluorocarbon (FKM) grades. Many formulations incorporate fillers or reinforcements such as graphite, mica, silica, or expanded PTFE, and may be produced as sheet stock, expanded PTFE, or pre-cut gaskets. Thicknesses commonly span from about 0.5 mm to several millimeters.

Properties: The materials are chosen for compressibility, memory, chemical resistance, and temperature tolerance. Depending on formulation, gasketen resist oils, solvents, or steam, and maintain sealing performance across a broad temperature range. Important performance metrics include compressive set, permeability, and long-term creep resistance.

Manufacturing and installation: They are produced by calendering or extrusion, then cut, stamped, or die-cut to fit flange faces. Proper surface preparation, correct gasket size, and appropriate torque or clamping force are essential to achieve a reliable seal; lubricants or anti-stick coatings may be used on some gasketen to ease installation.

Applications and standards: Gasketen variants are used in automotive, industrial machinery, piping systems, HVAC, and food processing when food-grade materials are required. Many gasketen products are manufactured to industry standards and carry material certifications for chemical compatibility and safety.
