The Ball That Outlasts the Game.
Diels-Alder reversible chemistry repairs micro-cracks on every impact. One MaddBall replaces 10–20 conventional balls. 330 million balls discarded every year — we built the fix.

The Science
Two Failure Modes. Two Solutions. One Ball.
Furan + Maleimide → Diels-Alder adduct · heat-triggered bond reformation
0 Patents
17+ years protection
Conventional pressurized tennis balls fail in two ways: the rubber core cracks under repeated impact, letting pressure escape irreversibly; and the felt cover wears down fast, shedding microplastics and losing spin consistency. Nobody has solved either — until now.
Diels-Alder reversible bonds auto-repair micro-cracks on every impact
Nano-silica + graphene oxide felt cover — 3× abrasion resistance
98% less microplastic shedding — sealed nano-felt locks fibers in place
ITF Appendix I compliant — built to exceed spec, not just meet it

What Sets It Apart
Six Reasons MaddBall
Changes the Game.
01
Self-Healing Core
Reversible Diels-Alder bonds in the elastomeric core repair micro-cracks on impact. Pressure, elasticity, and bounce stay stable across 500+ games — where conventional balls fail after 9–18.
02
Nano-Felt Cover
Nano-silica and graphene oxide reinforcement hardens the felt surface and locks fibers in place. 54+ games of durability vs. 9–18 for standard felt. Less than 5% spin loss by game 54.
03
98% Less Microplastics
Sealed nano-felt surface prevents fiber shedding during play. Less than 0.2g of microplastic per ball vs. 2–5g for conventional balls — a 98% reduction at the source.
04
Consistent Bounce
±0.1% bounce variance across extended use vs. ±5–8% for competitors. The same predictable rebound from the first point to the five-hundredth game.
05
90%+ Waste Reduction
One MaddBall replaces 10–20 conventional balls. Aligned with the ITF Sustainability Roadmap, EU Circular Economy Action Plan, and ATP/WTA carbon-neutral commitments for 2030.
