- Inverted (non-Chinese): This is the most widely used rubber type. The surface is smooth, with the pimpled side facing inwards toward the blade. This enables the player to generate high levels of spin and speed. Spin is mainly generated not by the action of the topsheet alone, but also by the ball sinking into the sponge and allowing greater surface area to contact the ball.
- Inverted (Chinese): Chinese rubbers typically have stickier (or "tackier") topsheets. Spin is generated mainly by the topsheet, as opposed to the sponge, which is relatively more condensed and firmer. The result is usually a far better short game and potential power capabilities than normal inverted.
- Short pimples (or "pips"): Short pimples-out rubbers are usually used by close-to-the-table hitters (for example, Liu Guoliang). They do not generate as much spin as inverted rubbers, but also make the user less susceptible to the opponent's spin. Speed generated from a short pip rubber is generally faster than the inverted with the same sponge. Depending on the thickness of the sponge it is also possible to play a chopping game with short pimples (an exponent of this style would be Ding Song) by varying the spin of the return. Whilst blocking and attacking a "dead ball" effect is often noticed.
- Long pimples (or "pips"): Long pimples-out rubbers carry relatively long and soft pips. They do not have the ability to generate any real spin of their own, but feed off the opponent's spin, to allow the user to confuse the opponent and upset their rhythm. Long pips are not very susceptible to the opponents incoming spin, and tends to "return" the opponents spin back upon impact, as the pips bend and slide. They are usually used by close-to-the-table blockers, or choppers. They are usually only used on the backhand side, as they offer very limited attacking capabilities. Depending on the grippiness of the sides of the pimples and the thickness of the sponge it is also possible to play an aggressive game with long pips, though with not much spin capability.
- Anti-spin: Anti-spin, like long pimples, cannot generate any real spin, but just allows the user to produce a no-spin ball. Anti-spin is also not very susceptible to the opponents incoming spin, due to the low coefficient of friction of the rubber's surface. This is also used to confuse the opponent, and is not widely used at international level.
