ABREX®-ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion tester. The simulated wear pattern matches reality with 99% accuracy. It is a highly complex abrasion process which involves:

• A 45° angle impact driven by a dynamic pneumatic cylinder attached with a viscoelastic fingertip under a defined load;

• Then a friction rubbing or tumbling motion between the sample and a textile containing dirt, dandruff, oil, sweat or various types of testing liquids;

Followed by a retraction movement with or without the contact at the surface depending on the application.

General abrasion is a common mechanical process on surfaces caused by scuffing, rubbing, or scratching under normal operation or under environmental exposure. Additionally, there is a special abrasion which is generated merely between human fingertip or hand and touched product surface. This special abrasion, namely ABREX®-ABRASION leads to distinct patterns of damages on the materials and its surfaces. It widely appears in many types of consumer products.
