Abstract
This invention pertains to a golf ball which includes a core, optionally one or more intermediate layers; and an outer cover layer. The outer cover layer and/or one or more intermediate layers includes a blend of a) about 2 to about 40 wt % (based on the total weight of the blend composition) of an aramid polymer and b) about 60 to about 98 wt % (based on the total weight of the blend composition) of one or more additional polymer components. The blend composition has a melt flow index (MFI) from about 1 to about 80 g/10 min., a material hardness of about 30 to about 90 Shore D, and a flex modulus of about 10 to about 120 kpsi.
