Description: It is made of expanded PTFE yarns with reinforced corner from continuous aramid filament, a combination of proved top qualities. It has high cross-sectional density and structural strength. This structure enhances the lubricability of aramid fiber and reinforces the strength of the pure PTFE packing. This special combination packing takes a very important role for high pressure piston pump application. It is recommended for piston pump in the universally applicable within the PH range 2-13. It is suitable to be used in Chemical, petrochemical, pharmaceutical, food and sugar industries, pulp and paper mills, etc.
