The objective of the test was to compare the abrasive properties of similar two polyurethane products in the market under laboratory conditions using a Taber Abraser.
First each specimen is prepared for testing and the surface is abraded by rotating the specimen under weighted abrasive wheels. Next the Abrasion Resistance is calculated as loss in weight at a specified number of abrasion cycles, as loss in weight per cycle, or as number of cycles required to remove a unit amount of material.
The Taber Abraser apparatus consists of the following elements:
- a horizontal turntable platform; comprised of a rubber pad, clamp plate, and nut to secure the specimen to the turntable
- a motor capable of rotating the turntable platform at a speed of 60 ± 2 revolutions/minute
- a pair of pivoted arms, to which the abrasive wheels and auxiliary masses are attached
- a load of 1000 g on each wheel using a changeable mass.
- a vacuum suction system and vacuum pick-up nozzle to remove debris and abrasive particles from the specimen surface during testing
- a counter to record the number of cycles (revolutions) made by the turntable platform.
Based on the results of the “Taber Test” by independent testing laboratory Excel Plas, the test conclusions confirmed that the Kinder Australia’s K-Superskirt® Engineered Polyurethane (red) abrades less by comparison to the competitors (blue) polyurethane.
The final result is further evidenced when tested at 50,000 cycles, wear index results showing 5.8 (red) compared to 25.92 (blue) or a ratio of 4.47: 1.
