GOLD BALL HAVING A FOAMED LAYER CREATED BY INFRARED RADIATION

摘要

This invention is directed to a golf ball having a foamed layer and the method for creating the foamed layer by the heating of blowing agents with infrared radiation. Either physical blowing agents can be de-volatized, or chemical blowing agents (both organic and inorganic) may be decomposed wherein the blowing agents are generated within the layer. The resultant layer is less dense than the core layer beneath it.
