| NA-1501-F the master of low coefficient. NA-1501-F replaced our asbestos formulas B-8 and BV-7. If LOW-CO is required this formula has been proven. Today it is very difficult to produce low coefficient friction materials with asbestos substitutes, the compounds available are already high in friction. This special formula is not an everyday production run but is used primarily in thickness over 1-1/2" and large drum diameters. | Click on Graph to Enlarge |
