Claim 18:
19. A method for producing a sliding material for a metal-plastic plain-bearing composite material comprising adding fillers that improve the tribological properties to a polytetrafluoroethylene polymer base of the sliding material, wherein the fillers are spherical filler particles and have the following proportions and particle sizes:
1-10 vol & barium sulfate,
10-15 vol % aramid,
1-8 vol % polyimide, and
1-8 vol % fluorothermoplastic excluding polytetrafluoroethylene,
and
a D50 value for
barium sulfate of 0.2 mm to 1.4 μm,
aramid of 30 mm to 90 μm,
polyimide of 1 mm to 20 μm and
fluorothermoplastic of 20 mm to 80 μm.
