Bronze filled PTFE contains a copper/tin alloy providing a better creep resistance than most of the PTFE alloys. It exhibits improved thermal conductivity, with high load-bearing capacity, and hence is most often used in hydraulic systems.
Bronze filled PTFE
Bronze filled PTFE contains a copper/tin alloy providing a better creep resistance than most of the PTFE alloys. It exhibits improved thermal conductivity, with high load-bearing capacity, and hence is most often used in hydraulic systems.
Bronze filled PTFE is both thermally and electrically conductive. The bronze enhances dimensional stability due to improved hardness, compressive strength, and resistance to creep. Bronze filled PTFE is not to be used in contact with oxidizing agents.
