Bowling Ball Material

Bowling ball material may be thought of as two independent components of a bowling ball, the coverstock and the inner-core material. Bowling ball material is essentially all poly-urethane based products. These products include additive materials and curing process variations, particularly for the coverstocks, yielding calculated designs in the final bowling ball construction.

The industry refers to various coverstock blends, however, in the following way: plastic, urethane, reactive resin, hybrid reactive, and particle materials. Each of these coverstock material variations yields to the performance range capabilities a given bowling ball possesses.

Typically, the plastic and urethane coverstocks are found in entry performance balls available in 10 lbs – 16 lb. weight, the reactive resin coverstocks are found in general performance range balls from 12 – 16 lbs., and hybrid or particle coverstocks in pro performance range bowling balls from 12 – 16 lbs.

Naturally, the coverstock is the most important factor in determining the right choice of ball for you but don’t overlook the importance of the inner core designs. Manufacturers will design cores made of urethane and polymer based products in varying density ranges, shapes, and sizes so the end result will influence the overall ball motion predictably as it travels down the lane.
