The K-Superskirt engineered polyurethane, a revolutionary skirting material available from Kinder & Co for conveyor belt applications was tested to compare the abrasive properties of two similar polyurethane products in the market under laboratory conditions using a Taber Abraser.
Each specimen is first prepared for testing and the surface is abraded by rotating the specimen under weighted abrasive wheels. The abrasion resistance is next 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 comprising 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 1000g 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 Excel Plas, the test conclusions confirmed that the Kinder & Co K-Superskirt (red) polyurethane abrades less in comparison to the competitor’s (blue) polyurethane. The final result is further evidenced when tested at 50,000 cycles, the wear index results show 5.8 (red) compared to 25.92 (blue) or a ratio of 4.47: 1.
