First of all, basketball in NBA games is different from ordinary basketball. There are many basketballs on the market with different materials, and the materials of various basketballs are also different. First of all, it is cow leather, which is astringent and not sticky when exposed to sweat. The bounce is soft and moderate, easy to control. Currently, this kind of basketball is used in the American NBA professional league. The second type of PU synthetic leather is economical and practical, and is a good leather for popular indoor and outdoor basketball sports. The third type of PU material has small pores on its surface and has a strong adsorption effect on water and electric heating.
As a high-level commercial league, the basketball used by the NBA league is a No. 7 basketball, which is specially customized and weighs about 600-650 grams. Their game balls, especially the materials used, are extremely special. NBA basketballs are made of synthetic rubber. The American NBA professional basketball game designated the ball as Spalding's basketball. Spalding rubber basketball is made of rubber leather and is mainly used for outdoor basketball due to its skin-like feel, waterproof, wear-resistant, mildew-proof, and salt-alkali resistance. Basketball skins can be designed in various colors and patterns.
From the above we know that those three materials are commonly circulated on the market. The material used in NBA games is not the cowhide used on the market, but kangaroo leather. Kangaroo leather is very strong, extremely malleable and elastic, so it is favored by many manufacturers. It is worth mentioning that since there are no sweat glands on kangaroo leather, the player's sweat will not stick to the ball dealer, making it an excellent leather material.
Because the production cost is expensive, and the game balls are not sold to the outside world, but are given as souvenirs to special items. Therefore, it has also resulted in the phenomenon of "a ball is hard to find". For example, when the Warriors won their 73rd regular season victory, Curry and Green fought for the ball. In the end, the organizers had a headache and had to cut the basketball into pieces, and then give it to each Warriors player as a souvenir. What's even more outrageous is that Chamberlain scored 100 points before this, and this basketball was auctioned in 2000 and sold for a high price of $25,000.
