Precision Triple-Zone Polymer Architecture: MPP Core with Concentric EPP & EVA Boundaries
Engineered Gradient Densities for Pinpoint Sweet-Spot Control and Edge-to-Edge Power Transfer.
Single-material paddle cores create dead zones and force players into rigid performance trade-offs. Our Model 2027-7 R&D Concept features a mathematically proportioned triple-zone core layout: pairing a central 90mm x 164mm Monolithic MPP Engine with a Low-Density EPP (355–370g) transition zone and an outer EVA vibration damping frame. Experience unprecedented shot control without sacrificing perimeter power.
Structural Blueprint Breakdown
1. Monolithic MPP Central Control Zone
Precision Center Core (90mm x 164mm):
High-grade Microcellular Polypropylene (MPP) forms the inner striking zone. Its isotropic pore structure maximizes ball dwell time for soft dinks, precise resets, and unparalleled directional control.
2. Concentric EPP Energy Transition Band
Low-Density EPP Frame (31mm Vertical / 29mm Lateral):
Surrounding the MPP center, a 355–370g EPP foam zone acts as a dynamic power bridge. It prevents energy dissipation during off-center contact while maintaining torsional stiffness.
3. Active EVA Perimeter Damping Rim
Vibration Isolation & Edge Expansion:
Encapsulated in a high-rebound EVA foam rim along the outer boundary. This layer absorbs high-frequency shockwaves before they transfer to the handle, protecting player joints and extending forgiving playability.
