How Are PTFE Bushings Made?
PTFE bushings are cylindrical linings made of low-friction material, which can withstand high friction and temperature. PTFE composite bushing combines the properties of different materials to make it ideal for application in material handling equipment, the automotive industry, and textile machinery. Let’s have a look at how PTFE composite bushing is made.
You need four ingredients to make PTFE bushing, water, fluorspar, chloroform, and hydrofluoric acid. The chemicals are combined in a reaction chamber in the pyrolysis process before they are heated at very high temperatures. When TFE is polymerized through radical polymerization into PTFE, it becomes fire resistant. This reaction is catalyzed by small amounts of ammonium persulfate, succinic acid peroxide, and water. There are two methods you could use to produce PTFE. These are suspension and dispersion polymerization.
Suspension polymerization involves getting PTFE grains that are processed into pallets that can be molded into bushings. Dispersion polymerization, on the other hand, involves producing PTFE in a milky form that is processed into a powder. Click on the link above to learn more.
