Abrasion resistance is one property of materials that can greatly improve safety. Abrasion resistance refers to a material's ability to withstand damage and wear caused by friction and rubbing against other surfaces. In workplaces where equipment and tools are constantly being used, abrasion resistance is particularly important.
