I. Advantages of the Inner Liner (Rubber-Plastic Core)
High-elasticity rubber-plastic formulation, with stable rebound.
Using natural rubber combined with synthetic rubbers (such as BR/SBR) and elastic reinforcing agents yields a better balance of hardness and resilience.
Bounce height is consistent: 135–147 cm (ITF standard), with slow degradation after repeated impacts.
It remains firm in the cold and supple in the heat, with consistent elasticity throughout all four seasons.
Strong constant-pressure / pressure-holding capability
The inner liner features more uniform wall thickness and superior sealing, ensuring long-lasting air retention (about 2–4 weeks for professional-grade balls, versus 3–5 days for standard ones).
With prolonged training, rebound and ball speed show virtually no noticeable decline, reducing interruptions caused by ball changes.
Deformation-resistant, impact-resistant
The rubber‑plastic matrix boasts high toughness, making it resistant to deformation and cracking under powerful impacts, and capable of withstanding repeated shocks.
Excellent shock absorption reduces strain on the wrists, elbows, and shoulders, making it ideal for high-intensity training.
II. Advantages of Felt (Surface Layer) Specifications
High density, high wool content
Wool ≥ 40%, with the remainder being high‑tenacity nylon 6/66; face density 300–350 g/m², approximately 30%+ denser than standard training balls.
Thin and dense (2.0–2.5 mm), with low aerodynamic drag, fast ball speed, and a stable flight trajectory.
Wear-resistant and anti-pilling
Knitted and sheared construction, with a smooth, short pile surface; wear after 500 high‑intensity impacts is less than 8%.
Hard court / clay—suitable for multiple court surfaces, with no crumbling and no sagging.
Strong rotational performance
The felt is dense yet offers moderate friction, ensuring excellent grip on the string bed and stable ball control, with enhanced controllability for topspin and slice.
III. Overall Performance Advantages (Compared to Standard Training Balls / Low-Pressure Balls)
Accurate ball feel: Hardness, weight (57–59 g), and diameter (65–67 mm) are rigorously aligned with ITF match balls, delivering crisp, clear feedback upon impact.
High durability: rubber‑plastic inner liner plus high‑density felt; lifespan is 3–5 times that of standard balls, making it more cost‑effective over the long term.
All-court versatility: Performs consistently on hard courts, clay, and grass, with excellent bounce, speed, and spin consistency.
High training efficiency: long-lasting pressure retention and stable performance, ideal for extended multi-ball drills and competitive play, minimizing variable-induced interference.
