Processed PTFE compounds are today the best solution on the market for very complex industrial applications.
The ability to operate in the absence of lubricants allows PTFE products to provide solutions in applications where the use of lubricants is impossible due to inaccessibility, external temperatures, the presence of chemicals or the risk of contamination, for example foodstuffs.
PTFE semi-finished products combine very well the wear resistance with a low friction coefficient in a wide range of applications with different conditions of use.
Polytetrafluoroethylene (PTFE) is a thermoplastic, inert, fluorinated polymer with the appearance of ivory.
Why are PTFE molecules inert and do not react with other molecules? We find the answer in the unique character of the chemical compound PTFE. PTFE molecules are made up of carbon and fluorine atoms. Of all the existing types of atoms, fluorine, once bound to a carbon atom, does not react with any other molecule. Therefore, the fluorine bonds of the PTFE compound are an effective barrier, protecting the carbon atoms and preventing them from forming bonds with any other molecule they would come in contact with. As a result of these bonds, the PTFE compound is used in a wide range of applications due to its special characteristics, among which we mention:
working temperature range between -200°C and up to 260°C
high chemical resistance
low friction coefficient
possibility to be used without lubricants

Gluing or cementing
Due to the high chemical resistance, PTFE products cannot be glued with any adhesive currently on the market.
In order to make gluing possible with other materials, the semi-finished product is subjected to a “cementing” process.
The “cementing” process consists of a chemical treatment of both simple and processed PTFE products. This treatment makes it possible for PTFE to be glued by means of special adhesives on different surfaces: rubbers, metals, plastics, etc.
Using this process, a wide range of simple and composite PTFE cementable products can be obtained on request.
