The new generation T3 carbon sponge adopts carbon big hole sponge developed from static foaming technology, the pores are relatively uniform in size and more evenly distributed, with excellent integrity and mechanical pr0perty. The carbon sponge provides stronger supporting force, compounded with the golden ration of the pores with the pore walls, so the rubber sheet keeps a larger compression ratio when the is battling and the elastic energy stored can be output more stably.T3 carbon sponge and shaped astringent plastic surface complement each other, bringing not only superior flexibility and power, but also excellent rotation performance and ability to control the ball, thus giving full play to the good-holding and strong- force features of T3 rubber sheet.
