ABREX®

Abrasion is a common mechanical process on surfaces caused by scuffing, rubbing, or scratching under normal use or environmental exposure. Fingertip & hand abrasion,namely ABREX®-ABRASION, is a specific type of abrasion due to the intensive interaction between the products and human fingertips and hands. This special abrasion leads to distinct and unique patterns of damages on the materials and its surfaces.

ABREX®-ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion. It is a highly complex abrasion process which involves:
• Firstly a dynamic impact with 45o angle by a viscoelastic fingertip under a certain load and the influence of
  various liquid;
• Then a friction rubbing or tumbling motion between the sample and a textile containing dirt, dandruff, oil,
   sweat or various types of creams.
Followed by a retraction movement with or without the contact at the surface depending on the application.


Thanks to the selection of pneumatic drive system, ABREX® is by far the only testing machine which can simulate fingertip & hand abrasion. With a good understanding of human physiology, ABREX®  is the only machine which translate the human touch into a standardized testing machine. Compared with other system which involves either linear drive, or gear system, only ABREX®  can simulate the human touch and hand movement. 

Current available models of ABREX® :
• standard ABREX: for DIN/IEC 60068-2-70, BMW GS 97034-1, -4
• ABREX-E: for BMW GS 97034-2 & 97034-3 tests
• ABREX-A: designed especially for touchscreen application
• ABREX-TRES: multi station ABREX for heavy duty testing capacity
• ABREX-C&-CE: for testing for a temperature range from -40°C to +85°C

ABREX® is currently the world standard machine for evaluatiing the abrasion resistance, dynamic scratch resistance of the material and coatings. It has been referenced in numerous standards and specifications including plastics, coatings, laminates, leather, paper, ceramics, glass, etc.).
