Materials: COF

By Dr. David R. Roisum 

COF, or Coefficient of Friction, is easily measured and informs us of many web-handling, winding and end-use concerns. Yet, it is not as commonly measured and thus may be the most under-appreciated of lab tests we discuss in this series.

Inclined bed and sled test methods are discussed. Applications such as roller and winder design and end-use requirements are discussed.
