Scope:
Taber abrasion is a test to determine a plastic's resistance to abrasion. Resistance to abrasion is defined as the ability of a material to withstand mechanical action such as rubbing, scraping, or erosion. Abrasion can be difficult to compare but haze variation or weight loss are often evaluated.
Test Procedure:
The haze or original weight of test specimen is measured. The test specimen is then placed on the abrasion tester. A 250, 500, or 1000-gram load is placed on top of the abrader wheel and allowed to spin for a specified number of revolutions. Different abrading wheels are specified. A haze measurement or final weight is taken. The load and wheel can be adjusted for softer and harder materials.
Specimen size:
Either a 4-inch diameter disk or a 4 sq. inch plate is used. A ¼ inch diameter whole in center is required.
Data:
Results are expressed by changes in % haze or in weight loss in mg/# of cycles.
Equipment Used:
Taber Abrasion Apparatus
Abrasion Wheels
