PTFE sounds like a lot of science, technology mothers giant. However, you may be surprised to find that PTFE is much more complicated than you think. In fact, you may now have some expanded PTFE in the kitchen.

Not just cooking, but also for industrial coatings applications such as aerospace, automotive and electronics. Among its top technology applications, PTFE is used for the construction of rocket propellant igniters. PTFE is also used to coat certain types of bullets. The low friction properties of PTFE prevent the wear of the gun through the barrel of the gun.

PTFE was so rugged and used during World War II to protect the first atomic bomb development of the building. The building measures more than 2 million square feet and contains large amounts of uranium hexafluoride. Uranium hexafluoride is highly corrosive, but the PTFE coating prevents these radioactive materials from leaking out of the building.

PTFE also has a more common application. In fact, you can use PTFE in almost every room of your house.

PTFE is usually used in shoes, insoles and orthoses to reduce friction and prevent blisters and hot. It is also used as a pipe seal tape - the tape that connects your pipe to the bottom of the kitchen sink may contain PTFE very well. It can also be used for insect control. When the surface is coated with PTFE, it becomes so slippery that the insect can not climb it.

You can also find PTFE in your garage. It is often used to paint automotive parts. PTFE is particularly suitable for ball bearings and gears and other coating components, because it can be a good resistance to friction, so that your car running smoothly. You may even use PTFE now; the bottom of the computer mouse is sometimes painted with PTFE to reduce friction and improve tracking. PTFE is very suitable for electronics because it is insulator and nonconductive.

In industrial coating applications, expanded PTFE is used in both coating systems, including primers and topcoats. In addition to providing very low friction and wear, the PTFE coating has the highest operating temperature of any fluoropolymer; it can withstand temperatures up to 600 degrees Fahrenheit. PTFE coating also has good chemical resistance.
