Coefficient of Friction (COF) Tester

The Coefficient of Friction Tester or COF Tester can perform Static Friction and Kinetic Friction test of substrates such as Paper / Plastic Films / Laminates, etc.

When paper / plastic films run on production lines, they come in contact with various parts like Metal Rollers, Hoppers, Chutes, Conveyors, etc. And every time there is a contact, there is also friction. Friction is required. It is a good thing when at an optimum value.

Too Low or Too High friction is bad for production, as it can lead to undesirable results such as Slip / Stretch / Scuffing / Breakage / Mis-Registration / Jamming, etc

Confirms to : TAPPI  T549 / ASTM D–1894
