To reduce friction on devices, an F-treat process provides a permanent low coefficient of friction surface that doesn’t dissipate with wear. Unlike topical modifications (molybdenum disulfide, graphite, silicone oil, or PTFE powder) that can be washed or worn away, F-treat modifies the entire compound so a low-friction surface is always present.Medical devices such as endoscopes use F-treated seals to provide surgeons with more sensitivity and “feel” for their instruments than nontreated elastomer seals. Medical-product designers improve nasal and liposuction canula with custom-designed F-treated seals and devices.Minnesota Rubber and Plastics, 1100 Xenium Lane N, Minneapolis, MN 55441, (952) 927-1400, www.mnrubber.com
