Why PTFE Fillers?

When looking at PTFE material wear properties, a factor between 1 & 10 is outstanding and between 10 and 100 is good. On its own, virgin PTFE has a wear factor of 5,000 so it is easy to see why a filler is necessary to prolong the wear life of PTFE. TRITEC uses all of the standard fillers necessary to achieve the required life expectancy for standard applications. These fillers are necessary because PTFE on its own does not offer the wear factor necessary to withstand the friction caused when in contact with the shaft. The quality of both the virgin PTFE and the chosen filler needs to be controlled very closely in today’s global market. That is why, back in 2010, TRITEC formed TRITEC Polymers.

With TRITEC Polymers as a new partner, TRITEC has been able to produce the highest quality PTFE rotary lip seals in the industry. It has also allowed us to create unique and proprietary blends for our customers, giving them a competitive advantage by providing seals with longer life. Because we control the sourcing of the resin, the formulation, molding and sintering of the selected blend, our customers are assured that their PTFE seals have the proper tensile strength and elongation needed for successful sealing. These two properties are critical to how the PTFE responds in the application for which it is designed. For a sample listing of our blends and their uses, please see TRITEC PTFE fillers. We will be happy to offer you the competitive advantage you require; just contact us and we will begin the process!
