..., tensile strength and tear resistance, elongation at break, and hardness. The wear behavior of elastomers is particularly sensitive to the abrasive impingement angle, because this influences the dominant modes of deformation and hence the wear mechanisms. At low impingement angles, tensile tearing occurs...
