Fundamental and specific properties of the tennis ball on rubber ball body are surveyed to match the quality of the tennis ball now on applied in the tennis game. 1. Much dose of filler of non-crystalline or flat form applied to rubber compounding than general procedure and over vulcanization is found excellent in the resistant to gas permeability. 2. Flat curing improved characteristics of the ball on the homogenous rebounds when applied on the specified concrete surface. 3. Satisfactory adhesive power is found with Desmodur R and standard rubber recipe in case of applying on the under-vulcanizate of half sphere. 4. The stable gas-generating compounds of sodium nitrate, ammonium chloride, water and sodium carbonate, anhydorus help controlling of optimum internal over-pressure in the ball.
