Characteristics & Applications:

1. F850: Similar to NEMA grade C, intended for mechanical applications(coarse weave), applications include gears and bearings

2. F851: Similar to NEMA grade CE, intended for use in electrical applications requiring good moisture resistance and good mechanical strength(coarse weave)

3. F852: Similar to NEMA grade L, intended for machining and mechanical applications requiring a fine edge detail and appearance is required(fine weave)

4. F853: Similar to NEMA grade LE, intended for electrical applications requiring good moisture resistance(fine weave)
