Sealing tape type e-PTFE
Sealing tape e-PTFE is produced of pure expanded polytetrafluoroethylene having a structure of micro-porous fibres, obtained in a special process of extrusion. The tape has a self-adhesive surface on one side, thanks to which installation is very convenient. It is characterized by good flexibility, resistance to compression, thermal stability non-flammability and high chemical resistance.
Application
They are designed to work in all utilities (except for melted alkaline metals and elementary fluorine). They serve for sealing of flange connections, hatches, covers, valves, fittings, pumps, heat exchangers, chemical equipment, ventilation draughts, air and water systems. They can be used for all types of flanges made of various materials: steel, aluminum, plastics, glass, ceramics, enamelled flanges or flanges covered with rubber etc.
