igus® materials in the test versus PTFE foils significantly more wear-resistant

Wear of machine parts depends on diverse influence factors. Thus designers are often confronted with the challenge of deciding between various material alternatives. With regard to wear behavior, igus® has now also compared its bar stock material iglide® A160, as well as its tribo tape material iglide® V400 on various counter partners with PTFE foils.

The trials were executed under the following test parameters:

Foils: iglide® A160, iglide® V400, and PTFE

Counter partners: Stainless steel, glass (in this case: Soda-lime glass, PET, and paper

Load: 2.25 lb

Speed: 0,722 ft/s

Temperature: 73ºF

Title: Rotating wear – foil test stand F=10 N (2.25 lb), v= 0.22 m/s (0.722 ft/s), T=23°C (73ºF)
x-axis: Counter partners (1.4305, soda-lime glass, PET, paper)
y-axis: Mass wear (mg/km)

Result:

The tests with the PTFE foil show an extremely high rate of wear against all counter partners. Compared with the PTFE foil, the two materials, iglide® A160 and iglide® V400, show significantly lower wear rates, see diagram 1 and 2.
