Abstract

PURPOSE: To accomplish prompt bouncing off the surface and elimination of excessively high sound with the thickness of a table tennis ball set to the same at that of conventional celluloid ball and the strength thereof equal thereto or more by adding a single special resin to the material of the ball.
CONSTITUTION: A thermoplastic synthetic resin such as polyethylene, polyvinyl chloride and acrylic resin is mixed with an inorganic matter of greater specific gravity than thereof, such as calcium carbonate, talc and aluminum hydroxide, and a fiber for example made of vinylon, organic matters (e.g. wool) an inorganic matters (e.g. asbestos) and thus, formed into a table tennis ball of uniform materials. The coefficient of water absorption of the thermoplastic synthetic resin used therein is about 3% or less and the specific gravity of the inorganic matter about 2 or more. The inorganic matter is to correct the weight of the resin alone in single form, while the fiber is to compensate possible embrittlement due to the addition of the inorganic matter.
