Wear behavior

Unfilled: PTFE, modified PTFE, Moldflon™ In the short-term wear test Moldflon™, particularly in the unfilled state, significantly differs from PTFE and modified PTFE. As shown in the graph, wear in this test amounts to only about 10% of the value compared to PTFE and modified PTFE. This quality leap is the result of the special molecular structure of Moldflon™.

Filled: carbon fiber compound
In the long-term wear test compounds based on Moldflon™ – with the same filler content – show lower wear than compounds based on PTFE. The following figure illustrates this, using the example of carbon fiber compounds with a filler content in the range between 10 and 20%.

In addition, it is obvious that, as the filler content increases, the wear-reducing effect of Moldflon™ compounds is higher than that of PTFE-based compounds. The reason is the better setting of the filler particles within the polymer matrix. The better the setting of the fillers in the polymer matrix, the longer the duration of the wear-reducing effect.
