Do you have the characteristics of high density sponge:
In our country, technical professional players generally use domestic sponge for backhand and imported sponge for forehand. But now a lot of joint venture sponge appearance characteristics have been close to imported goods, so it is generally not easy to distinguish.

① The common sponge is divided into high density sponge, molar mass formula sponge and low density sponge according to the structure-high density sponge.
Common sponge is divided into 30 degrees -55 degrees (from soft to hard) according to strength, and the thickness is generally in the middle of 0.3-2.3mm. Sponge produced by different manufacturers is still different in ductility although sometimes the myopia degree at the base price is the same. Pay attention to high-density sponge when purchasing.
③ Common sponge is divided into reverse sponge (with reverse paste sleeve glue) and positive sponge (with positive paste sleeve glue) according to its main purpose.

Do you have the characteristics of high density sponge: The common sponge on the sales market is also divided into two categories: imported and domestic. In the past, it was very easy to distinguish from the appearance and touch. Imported sponge has good ductility, thin and well-proportioned, light net weight, stable quality and slightly soft touch. The arc ball rotates strongly and the route is standard. The net weight of domestic sponge is heavier, the ductility is slightly different, and the touch is slightly hard. Some of the loops float and move down (as the saying goes, better than thieves).
