40% Bronze filled PTFE Rod Bar 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. 40% Bronze filled PTFE Rod Bar 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.
Applications:
The major uses for 40% Bronze filled PTFE Rod Bar are: bearings, piston rings (hydraulics), valve seats and plugs. It is also used for support slides of heavy loads subject to several shocks.
Advantages:
• The best wear properties of any filled PTFE
• Very heavy – high specific gravity
• Extremely hard wearing material
• Great deformation strengths
• Good thermal conductivity
• Electrically conductive
