These tennis balls are formulated for recreational beach play where cost efficiency and durability against sand, moisture and UV exposure are priorities. The construction balances a low‑cost rubber core with a felt covering that meets basic performance thresholds for bounce and feel while keeping unit price low for bulk procurement.
Typical values are based on internal testing of production lots; actual measurements may vary within accepted tolerances.
| Property | Typical Value | Test Method |
|---|---|---|
| Diameter | 6.55 – 6.86 mm | ISO 20957‑2 (caliper) |
| Weight | 56.0 – 59.4 g | ISO 20957‑2 (balance) |
| Rebound Height (100 in drop) | 135 – 147 cm | ISO 20957‑2 (rebound) |
| Internal Pressure | 1.8 – 2.2 bar | Pressure gauge (core puncture) |
| Felt Composition | 65 % nylon / 35 % wool blend | Fiber analysis (FTIR) |

The core is molded from a styrene‑butadiene rubber (SBR) compound selected for its low cost and adequate elasticity. After molding, the cores undergo a pressurization step to reach the target internal pressure, then are cooled to stabilize dimensions. The felt covering is applied using a latex‑based adhesive that bonds the nylon‑wool blend to the cured core, providing a uniform surface that resists delamination under repeated impact.
Beach‑side play subjects balls to abrasive sand, occasional splashes, and prolonged sunlight. The selected SBR core exhibits low water absorption, limiting weight gain when wet. The felt blend is treated with a UV‑stabilizing additive during dyeing, reducing surface degradation after extended exposure. These attributes make the balls suitable for casual beach tennis, paddleball, and similar low‑impact racket games where official tournament specifications are not required.
Each production lot undergoes a sampling plan based on ISO 2859‑1. Inspectors measure diameter, weight, rebound height and internal pressure on a statistically significant sample. Balls that fall outside the defined tolerances are segregated and reworked. Visual inspection checks for felt adhesion, surface uniformity and absence of foreign particles before packaging.
Buyers can specify variations that affect cost and performance without altering the basic construction.
Standard packaging places 3 balls per polyethylene sleeve, 48 sleeves per corrugated carton (144 balls). Cartons are sealed with moisture‑resistant tape and stacked on pallets with a maximum height of 1.6 m to maintain stability during transit. For overseas shipments, a desiccant packet is included in each carton to mitigate humidity‑induced weight change.
Yes, the core molding process allows diameter tolerance adjustments within ±0.3 mm; please provide the target range when requesting a quotation.
Required details include order quantity, desired core hardness, felt composition, any branding specifications, and preferred packaging method.
Each carton contains a silica‑gel desiccant packet and is sealed with moisture‑resistant tape; pallets are wrapped in stretch film to limit ingress during handling.
