PTFE is used in a variety of applications that goes from wiring in aerospace to non-stick coating in cookware. Some of the PTFE properties, such as high chemical stability and good conformability, makes it excellent for use as a gasket material, especially with aggressive media, pharma and food applications.

The scope of this paper is to present an innovative PTFE gasket manufacturing method for sealing aggressive media. The patented technology represents a unique production process that improves reliability, reduces cost and material waste when compared to traditional production methods. The gasket can be tailored to meet specific needs making it possible for customizations such as radial density variations, assorted colors compositions according to the gasket region and properties, or even use of distinctive fillers along its radius. Comparative data are reported among the developed technology and traditional processes.
