Test principleRCA paper tape abrasion tester uses special test paper tape as abrasion medium and acts on the abrasion head with a fixed load. The abrasion head drives the paper tape through a roller with a fixed diameter and a constant speed motor to continuously apply force to the surface of the sample until the surface substrate is seen or a specific abrasion degree is reached. The abrasion resistance of the sample is evaluated by the number of motor revolutions displayed by the counter.
