ABREX^®

Chemo-mechanical Hand Abrasion

Basic Functions

Damage to a surface by the human hand is one of the main reasons for the sustained disturbance of a product's valence. ABREX® tests the finished product or the lab sample regarding high-complex viscoelastic process of hand abrasion and its chemical environment.

Advantages:

• Reproducible results due to standardised test procedure
• Practice-oriented testing by chemo-mechanical abrasion
• Universal use by flexible unit design

Soft chemo-mechanical hand-abrasion test acc. to:
