Bellows are used to protect moving parts of machines against dust and dirt, to absorb vibrations and correct shifts. The durability of a bellows is a very important requirement. The properties of modified PTFE, excellent chemical resistance, long flex life and high temperature resistance makes a very good material in high demanding applications.
Polyfluor can support designing a bellow meeting your specific ideas and requirements. We can help you through the entire process, from design to the finished product. All bellows we supply are custom-made for purpose.
Machined round bellows are suitable for medium pressure applications (up to approximately 6 bar). As a result, you run much less risk of contamination of a machine because it is much easier to keep clean.
Polyfluor also supplies bellows for high pressure and vacuum applications. For example, a different design is desired within piping systems, such as a thicker wall thickness. This makes it a lot stiffer so that the movement is also much more limited. In addition, the installation length is a lot longer. Vibration or light movement (axial, lateral or angular rotation) is often also a reason for the application of this type of product.
PTFE bellows from Polyfluor are often used in machines in the chemical and petrochemical industry, the packing & food industry, the automotive industry and the pharmaceutical industry. In addition, Polyfluor also supplies to various other industries.
We not only supply bellows, but almost everything to support the production process. For example, Polyfluor supplies membranes, seals, injection molds, fibres, glass fibre, fluoroplastic tubing, heat shrink tubing and cleanroom tubing. Whatever the question is and whatever industry you are in, Polyfluor can always offer you a total solution.
