The Defender features Durability Optimization Technology (DOT), a patent-pending advancement in bowling ball technology.
Over the past eighteen months, the Brunswick Research and Development team has worked hard to develop the next breakthrough in cover technology. After pouring and throwing hundreds of bowling balls with dozens of new base reactive urethane formulations combined with a wide variety of chemical components and additives, our ball team has created something exceptional – the new HyperKinetic22 coverstock.
HK22, as we’ll often refer to it, features enhanced color and clarity by engineered nano microcellular phase separation technology, dramatically improving the cover’s translucency. And through Quasi prepolymer staged reactions, intermolecular friction is reduced to manifest a dynamic interactive polymer morphology with the lane. To simplify this, bowling balls featuring HK22 look better on the shelf and perform better on the lanes with a shiny finish that provides easy length and increased dry lane friction for impressive backend reaction. HK22 is an exciting technological advancement, and we believe this is just the beginning as our chemists continue their work to push the limits of bowling ball performance.
As always, each brand will continue to do independent testing with unique additive packages to supply the market with the broadest range of ball motion in bowling.
The new Brunswick Defender Hybrid is the first ball introduced using HK22. You’ll first notice the shelf appeal and colors of the Defender Hybrid and how they pop; this is due to the new translucent base material. The new base material HK22 creates a noticeable and exciting advancement in shiny ball hook potential, creating more teeth in the mid-lane for a shiny ball and a stronger, more responsive breakpoint. The ACT 3.0 additive package was added to the HK22 base to achieve optimal ball reaction. The overall result is more backend and a shiny ball that will handle more volume and give the bowler more area at the breakpoint.
DYNAMICORE
The Defender features Brunswick’s innovative outer core technology called DynamiCore. This industry-leading technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry.
