BUTTERFLY RUBBER CHARACTERISTICS

A table tennis rubber is made from a combination of a top sheet and a sponge (except for rubbers without sponge).

Top Sheet

The top sheet is the surface on which the ball hits. Therefore, the performance or characteristics of the top sheet has a significant influence on the game. Butterfly rubbers are available in black and red top sheet colors for each rubber. As stated in the ITTF Rules, "The surface of the covering material on a side of the blade, or of a side of the blade if it is left uncovered, shall be matt, black on one side, and of a bright colour clearly distinguishable from black and from the colour of the ball on the other". This means if black rubber is applied to the forehand side, red rubber must be applied to the backhand side (or vice versa). There is no difference in rubber performance between different top sheet colors.

Sponge

The sponge thickness/hardness varies the performance of the rubber which influences your game.

Sponge Thickness
Each rubber has a lineup of multiple sponge thicknesses. You can choose your sponge thickness depending on the performance you desire.
