Abstract
A process for making an anti-friction material consisting of mixing between about 68 per cent and 84 per cent by weight of a plastic material in powdered form with between about 12 per cent and 28 per cent by weight of glass micro-globules with a grain size from 1 to 44.mu. and a density of 1.45 kg/l, and an antistatic material, and then in heating this mixture at high pressure.
Claims5
A moulded antifriction material having very good resistance to wear consisting essentially of, by weight, from about 68 to about 84% of polyethylene having a molecular weight from about 1.times.10.sup.6 to about 6.times.10.sup.6, from about 12 to about 28% of glass micro-beads having a grain size of from about 1 to about 44 microns and a density of about 1.45 kg/l, and the balance comprising an antistatic material.
A moulded support for frictionally supporting an endless belt conveyor made of plastic material used in a papermaking machine, said moulded support comprising an antifriction material having very good resistance to wear consisting essentially of, by weight, from about 68 to about 84% polyethylene having a molecular weight from about 1.times.10.sup.6 to about 6.times.10.sup.6, from about 12 to about 28% of glass micro-beads having a grain size of from about 1 to about 44 microns and a density of 1.45 kg/l, and the balance comprising an antistatic material.
