PTFE is created by the radical vinyl polymerization of tetrafluoroethylene (TFE) resulting to create a strong fluorine carbon bonds that are resistant to almost all chemicals and solvents.
PTFE can perform under a very wide range of temperatures, (-300F to 500F) is non-flammable and acts as a thermal and electrical insulator.
PTFE is very slippery by nature and is perfect for applications in which external lubricants cannot be used.
PTFE has no memory and any the PTFE seal will permanently deform under compressive load. (Creep or Cold Flow)
As a result of this, PTFE is sometimes used in conjuction with standard elastomers to protect from any permanent deformation.
PTFE can also be filled with a variety of ingredients to provide better resistance to deformation, stronger physical strength or superior wear resistance.
Fillers like Glass, MoS2, Carbon, Graphite, Bronze, Stainless Steel and others can be used to resist Creep, improve wear resistance, and allow thermal or electrical conductivity.
The lack of chemical reactivity of PTFE products, ease of sterizilation, lubricity and hydrophillic properties a wide variety of medical products to use PTFE components.
PTFE can also be coated to a variety of elastomer, or metal components to provide superior performance over standard materials.
PTFE CANNOT BE USED IN FLUORINE, CHLORINE TRIFLUORIDE OR MOLTEN ALKALI SOLUTIONS AT HIGH TEMPERATURES.
