PTFE bushings - 55% Bronze + 5% MoS2 filled

We are producer and distributor of these 55 percent Bronze  and 5% MoS2 Filled PTFE bushings. Bronze and MoS2 as PTFE additives enhance creep tolerance, thermal conductivity, and wear resistance while maintaining low friction properties.

55% Bronze + 5% MoS2 filled PTFE has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has good to average chemical resistance in the presence of acids and alkali. PTFE bushings - 55% Bronze + 5% MoS2 filled PTFE bushings are 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.

If good thermal and electrical conductivity is required in your application, bronze-filled PTFE bushings may be ideal. It also increases wear resistance by adding bronze to PTFE.

Bronze, however, counteracts the PTFE's non-stick properties and chemical inertia, so you should take into account whether these are crucial to your specific case. According to their specific characteristics, other materials such as titanium, nickel or stainless steel (as mentioned above) may also be selected as fillers.

Bronze filled PTFE bushings, especially at higher pressures and speeds, have outstanding wear properties. Bronze-filled components are not appropriate for electrical applications for chemical applications.

PTFE bushings - Bronze filled are available in brown with a hardness of 60 shore D. The mixing ratio is 55 bronze + 5% Mos2 + 40% virgin PTFE.

Compressive strength, thermal conductivity and electrical conductivity have been improved. It has also reduced the tendency to extrusion while maintaining good sliding and wear properties, making it the standard material for hydraulic applications.
