Paperboard Abrasion Tester - OpTest

Corrugated cardboard boxes and paperboards are subject to significant vibrations and friction during feed to a box making machine or cargo transport. Surface abrasion resistance is important for avoiding peeling under such actions. This tester measures the resistance of paperboard to surface abrasion. Specimens are fixed to two different friction parts in the arc form. A couple of specimens of the same direction (MD or CD) rub each other on the test surface. The number of reciprocating motions is read on the counter, till fibers remove from the surface or abrasion occurs.
