Graphite Fibre Packing Impregnated PTFE
PTFE yarn packing filled with graphite and saturated with oil. It has a low friction coefficient, high chemical resistance and thermal conductivity. Packings from PTFE with filling of graphite are used in elements of machines and devices (e.g.: in centrifugal pumps) working in the environment of water, steam, oil, solvents, acid and bases, at temperatures up to +280°C and pressure up to 10 MPa.
