Porous fluoroplastic braid "Poroflex" is a chemical-resistant
self-lubricating packing and gasket material intended for use in
pumps and compressors, valves and fittings and pipes operated
in:
- heating, water supply and ventilation systems;
- chemical and pharmaceutical industries;
- oil-refining and gas-processing industries.
"Poroflex" is a braid with a circular or rectangular section
made from PTFE-D by extrusion and thermal treatment.
"Poroflex" has a number of advantages as compared to ordinary
FPM braids made from PTFE-D (FPM "V") because it has a special
porous structure:

Additional advantages of the porous braid "Poroflex":
- absolute resistance to all types of chemicals, including acids,
alkalis, solvents and aggressive oxidants;
- due to high strength and plasticity, "Poroflex" can easily
adapt to any (even corroded) surfaces, smoothen any roughness and
eliminate flange skewing;
- low friction coefficient prevents rod wear;
- can be easily removed during maintenance operations as it does
not stick to the walls of a stuffing box;
- environment-friendly.
Fluoroplastic porous braids "Poroflex" can be supplied in the
