Our flexibility allows us to manufacture from one unit up to the great series, being able to personalize with colors your piece, starting under sample or plane. Our machining limitations are 750mm diameter, which combined with our high specialization and quality in the processes, allows us to be probably the most versatile and specialized company in the manufacture of PTFE bellows and other types of technical parts.
The main application of machined PTFE is as a sealing gasket or sealing gasket in extreme corrosion conditions, since it is resistant to the majority of chemical agents in the industry, both in high and low temperature, since the range of working temperatures goes from -200ºC to +273ºC, although due to its low coefficient of friction, it is also used as a sliding or non-stick material in sticky or welding processes.
Our extensive knowledge and experience with PTFE in the construction of sealing gaskets and PTFE parts, allows us to advise on the design of new parts from our technical department and provide solutions for new applications.
