Answer by author The friction coefficient of solid PTFE bodies on stainless steel surfaces in liquid nitrogen is essentially unaffected by the filler. Friction coefficient is normally 0.08. Wear of the unfilled PTFE is 3 to 10 times that of the material considered in this report. A more complete answer can be found by referring to the paper "Wear and Friction of Filled Polytetrafluorethylene Compositions in Liquid Nitrogen" by D. W. Wisander, C. E. Maley and R. L. Johnson, ASLE Transactions, Vol. 2, No. 1, pp. 58-66, April, 1959.
