40% Bronze Powder Filled Teflon PTFE Tube, this bronze powder filler has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has poor chemical resistance in the presence of acids and alkali. Bronze powder filled PTFE is useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat
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
Application:
• Linear bearings
• Hydraulic seals
• Extrusion rings
• Piston Rings
• Guide ways
• Wear pads
• Bushings
• Bearings
• Sliders
