PTFE (Polytetrafluorethylene)

PTFE is a high performance plastic which is valued for several industrial applications. Among others, we process the following PTFE (fluoropolymer) materials:

Sample application: PTFE bellows

Sample application: PTFE bubble tray

Sample application: PTFE inlet tube combination

PTFE (Polytetrafluorethylen), also known as the trade mark Teflon® , is a high performance material, which is valued for several industrial applications because of its many positive technical properties. According to the individual field of application and the requirements on the finished PTFE products (e.g. deformation, applications with explosive environment (ATEX), flexibility, welding, surface properties), we provide the best suitable PTFE materials as well as comprehensive services around PTFE processing, e.g. engineering, design, technical documentation and after sale services.

 

Sample applications or typical PTFE products are e.g.: bellows and expansion joints, parts of chemical columns and reactors, inlet tubes, repairing systems for chemical vessels , floats, gaskets, linings and coverings, agitators, sliding elements, sliding bearings with inserted PTFE pads (IBG Monforts Gleitlagertechnik) and PTFE coating systems (IBG Monforts Oberflächentechnik).

 

All above mentioned PTFE and PFA materials can also be combined and manufactured with steel components or as complete devices (component parts). As there exist many approvals as FDA, 3-A Sanitary, USP Class VI, BAM, even the use in sensitive fields of applications like pharmaceutical industry and food industry is unobjectionable.
