This packing has the characteristics of good corrosive resistance, wear resistance, higher mechanism strength, and good self lubricating, small friction coefficient and small torque, however, its heat conductivity is bad and the thermal coefficient of expansion is big, so the measures of forced cooling and lubrication must be adopted for sealing on position with high linear velocity, so as to avoid burning packing and increasing wearing.
