摘要： A bladder shell for inflatable balls having at least a pair of layers of compounded synthetic latex and compounded natural rubber latex or at least a layer of blended synthetic latex and natural rubber latex compounded with anti-oxidant, activators, accelerators, thickening and wetting agents, stabilizers etc. to form a low air permeability and high bounce bladder shell having thickness of between 0.25 mm to 3.0 mm. The present invention also defines a process for the preparation of the bladder shell comprising formation of at least a layer of natural rubber latex and a synthetic latex each. The process of the present invention comprises dipping the former in not only a natural rubber latex bath but also in the synthetic latex bath. In an another embodiment, the process comprises dipping the former in the bath comprising blended natural rubber latex and synthetic latex.
