① Cattle skin: provided by GANASON, a world-famous leather manufacturing factory, selected from the first layer of natural skin on the back of cattle, and used to manufacture the top products of Spalding brand basketball series. This basketball emphasizes the touch of ball control, the skin is astringent and not sticky when it meets sweat, and the bounce is soft and moderate, which is easy to control. However, it is expensive and difficult to maintain. It is only used for indoor wooden floors and is usually used in professional competitions. This basketball is currently used in NBA professional leagues in the United States.
② ZK superfine fiber: a synthetic material containing "Spalding" patented ingredients. It has the advantages of delicate feel, sweat absorption and anti-slip, wear resistance, mildew resistance and easy maintenance compared with natural leather. Basketball made of it is usually used by professional teams for training and competition. At present, this kind of basketball made of ZK superfine fiber is used in the official competition of CBA A men's basketball league and the training of each participating team in China.
③ PU synthetic leather: With the strengthening of people's awareness of environmental protection, PU synthetic leather is a new material used to replace traditional natural cowhide products. Basketball made of it has the advantages of waterproof, wear resistance, mildew resistance and being suitable for indoor and outdoor use. Although it is also called PU synthetic leather, there are many kinds and grades in the market. In order to ensure the product quality and prevent counterfeiting, we only use the special PU synthetic leather materials provided by Yantai Leather Factory, the largest leather factory in China and imported.
④ PVC synthetic leather: Although it is slightly inferior to PU synthetic leather in hand feel and low temperature resistance, it is superior to PU synthetic leather in water resistance, wear resistance, mildew resistance and saline-alkali resistance, and it is a good skin material for indoor and outdoor basketball. Similarly, we only use special PVC synthetic leather materials provided by imported and domestic professional leather factories.
⑤ synthetic rubber: "Spalding" has a patented double-layer synthetic rubber production process, which is the best outdoor popular basketball skin material because of its leather-like feel and excellent waterproof, wear-resistant, mildew-resistant and salt-alkali resistant abilities. After the traditional process, the high-quality "Spalding" synthetic rubber basketball has changed people's one-sided view that rubber basketball is a low-grade and inferior ball.
