Fluoroplastic packing material (FPM) is "green" or unsintered
fluoroplastic-4D (PTFE-D) which is a fine variety of
polytetrafluoroethylene.
It is intended for use in aggressive liquid and gaseous media,
except for alkali metal solutions, trifluorochlorine and elementary
fluorine.
Due to its unique properties, fluoroplastic can be used as
packing material. The following products are fabricated for these
applications:
- FPM braids with circular or rectangular sections;
- FPM tapes.
FPM braid can be used as a gasket in static seals and sealing
glands/stuffing boxes in pumps and valves & fittings operating
under high temperature and in aggressive media.
FPM tape is used as a thread sealant for pipes made from any
materials and operating under temperatures from -60 to +200
îÑ and media pressure of up to 10 MPa, and as a sealant
in systems carrying both general industrial media and
highly-aggressive media. The tensile strength is up to 6 MPa,
elongation - from 40 to 95%.
