PTFE is an excellent choice for a wide range of products and applications. This material offers broad chemical resistance, high durability over a wide service temperature range, excellent dielectric properties and low coefficient of friction.

ptfe is a polymer and belongs to a group of chemicals called PFAS (fluorinated polymers). It has thousands of carbon atoms chained together in a molecular structure.

This makes PTFE very resistant to chemicals and more stable than many other PFAS. It is also electrically inert, which is very important for a wide variety of applications.

It is a very durable material that can resist high temperatures and has one of the lowest friction coefficients of any polymer. It is used to make low-friction bearings, valves and pumps. It is also used to make heat-resistant insulators for electrical cables and connectors.

Due to its flexibility, PTFE can be stretched to form membranes that are used to transport water vapor. These are often referred to as Gore-Tex membranes.

These are made from PTFE by a process known as paste extrusion. A lubricant such as odorless mineral spirits naphtha or kerosene is mixed with the polymer and the resulting paste is heated until the lubricant is removed.

Then, the film is submitted to either uniaxial or biaxial stretching. During this stretch, the PTFE is able to create a micropore structure and the result is an extremely inert membrane that can handle even harsh streams.

This substance is used in a number of medical devices and equipment because of its non-toxic properties. It is also a popular ingredient for coatings on cookware and other kitchen tools because it is an excellent non-stick material. It can also be stretched to make a mesh-like structure that is useful in procedures such as vascular grafts and hernia repair.
