Rubber Bladder
1. 50% butyl content 2. With high wear resistance and corrosionproof, not easy to be damaged by oxidation and ultraviolet light. 3. Good elastic, strong toughness, not easy to broken, long service life, with good air tightness.
Winding Bladder
1. Winding on the bladder surface, more than 2000 meters, winding dozens of layers and uniform distribution. 2. Use 3 wires of chemical fibe and 1 nylon wire, 360° multi-layer tight winding. 3. Be better ball support, avoid to long-term use of deformation. 4. Ensure the stability of the ball, and have good elasticity and wear resistance.
Laminated carcass
1. Tight structure, no impurities, can be well combined with glue, not easy to degumming. 2. The nature rubber is in the out of the winding bladder, vulcanized the outside rubber, yarn and bladder together and provides external support. 3. Smooth surface, uniform thickness, maintain roundness, soft, improved the stability of reboundness and better hand-touching.
