Abstract
The present disclosure provides extruded PTFE composite tubes with a reduced coefficient of friction (COF). In some embodiments, such extruded PTFE composite tubes may exhibit a reduced change in coefficient of friction between about 20° C. and about 40° C. with the inclusion of secondary polymeric particles with small particle sizes (<100 μm) at loading percentages of less than about 50 weight %.
