ABREX^® – Abrasion Tester

Abrasion is a common mechanical process on surfaces caused by scuffing, rubbing, or scratching under normal use or environmental exposure. The product with abrasion leads to the undesirable disturbance of its functionality, quality perception and value. Fingertip and hand abrasion is a specific type of abrasion due to the intensive interaction between the products and human fingertips or hands. This special abrasion leads to distinct patterns of damages on the materials and its surfaces.

ABREX^®-ABRASION, namely soft-chemo-mechanical fingertip & hand abrasion, is a highly complex abrasion process which involves:

• Firstly a dynamic impact with 45° 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.

ABREX^® is by far the only testing machine which can simulate this complex abrasion with different standard textiles under different chemical environments.

Furthermore, other tests can be also performed with the standard ABREX^® and with a high-speed ABREX^®-E, including:

• Dynamic finger-nail scratch automotive
• Dynamic industrial scratch
• Dynamic shoe sole abrasion
• Abrasion with soiling materials
• Abrasion with high-abrasive cleaning materials
• Cleanability test
• Limpness Test

In addition, all tests can be applied either on a lab sample or on a finished product with the testing temperature ranging from -40°C to +85°C.

ABREX^® is currently the world standard machine for evaluating 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.).

Technical Data

Adapters

Fingerprint Test

Generation of a standardized fingerprint on the surface (eg. touch screen, glossy piano paint) followed by a cleanability test on ABREX^® to test how easily the fingerprint is cleaned by microfiber cloth.

Steering Wheel Abrasion Test

A complete car or truck steering wheel mounting on ABREX^® for the simulation of ABREX^®- abrasion and other scratch tests without cutting the lab samples. The steering wheel can be any size from automotive, trucks and omnibuses.

Steering Wheel Abrasion Test with Wear Analysis

This adapter enables a complete car or truck steering wheel mounting on ABREX^®, and additionally the TRACEiT^® can be fixed onto the top of the adapter to provide an easy measurement of the abrasion rate and surface roughness, topography, structure and visual impression in a mobile fast fashion.

Banknote Durability Test

A specially designed sample mounting adapter with a certain curvature enables the simulation of ABREX^® -abrasion and other tests directly on a banknote with standard fabric, soiling fabric under both dry and wet condition.

Banknote Limpness Test

Limpness is referred as the banknote paper is less stiff due to the frequent handling. Limpness is normally correlates with soiling and structural deterioration, which results in a marded lack of stiffness. A specially designed adapter for ABREX^® enables the simulation the abrasion between the banknotes for evaluation of the limpness.

Teeth Abrasion Test

A specially designed adapter to simulate the tooth abrasion for testing the durability of tooth replacement materials. The materials of abrasion counterpart can be customized.

X-Y Sample Holder with Counter

A sample holder is designed with easy handling in both X & Y directions. An additional counter is supplied for better location of the sample.
