Specification of Gasket Black Hyper Valqua GF300
BLACK HYPER is the final form of sheet gaskets. Mainly consisting of graphite, silica and using PTFE as a binder, the GF300 is a versatile series of sheet gaskets that are very good at chemical resistance and find various application fields that are subject to a wide temperature range. Thus, BLACK HYPER is suitable for broad application fields as an alternative to non-asbestos for Asbestos Compressed Fiber Sheets.
is completely free of rubber, there is no heat damage that occurs, thus, the GF300 can be used for high temperature applications (heat resistance at 300 ° C). The use of flexible resin binders results in better properties of friability and defects compared to expanded graphite sheet gaskets. Water, seawater, hot water, steam, air, acids (excluding oxidizing acids such as heat, concentrated sulfuric acid and nitric acid), weak alkalis, salt water solutions, oils, alcohols, aliphatic solvents and vapors, and liquefied acid gases and oxidizing agents which are susceptible to combustion such as oxygenConnection of pipe flanges and valve hoods, flange and nozzle flanges in towers & tanks, ovens, pressure vessels and heat exchangers used in various plants including power plants, oil refineries, iron works, and shipyards 〈 Width × length〉 （mm） 1270 × 1270 (t 1.0, t 1.5) 1500 × 1500 (t 2.0, t 3.0) 〈Thickness〉 1.0, 1.5, 2.0. 3.0 mm 〈Color tone〉 Black (print color: black
