Norplex-Micarta BR70 Phenolic Canvas Laminate Sheet
Categories: Polymer; Thermoset; Phenolic

Material Notes: BR70 is a red colored composite made from a 24 oz/sq. yd canvas which is passed through the treater twice to insure impregnation of the fibers and to obtain the resin content desired for optimal performance. The resin system is a phenolic with good impregnation qualities and cured hardness. BR70 is designed for highly loaded bearing applications, where the lubrication is provided by oil, water or a mixture.
