Containing lots of metallic filling and modifiers, DF-105 has high metal content, so it has excellent heat conduction performance, stable dimension, is abrasionproof. It is the type with highest compressive strength among all DF series materials.
It is suitable to be used in manufacturing rubbing parts work in high PV condition(≥20Kg.M/cm ² .s), like seal/support rings on hydraulic cylinders, sealing surfaces for large valves, and axle bushings.
