Table tennis rubber

[1] The thickness and density of the sponge layer underneath also affects how the rubber will handle the ball.

The International Table Tennis Federation (ITTF) regulated the thickness of the foam + rubber layer to a maximum of 4 mm (1⁄6 inch) thick, which has been the regulation in table tennis since.

On July 1, 1986, two years before table tennis's introduction to the Olympics, the ITTF made it a rule that competition paddles had to have black rubber on one side and red rubber on the other side.

[1] They are smooth on the outside, leaving the pips on the inside touching the foam, which is why it is called inverted.

[2] Inverted rubber's wide variety of speeds and spins make it a favorite among players.

Manufacturers will provide speed and spin ratings to differentiate their type of inverted rubber from others.

[6] After the ITTF banned speed glue due to health concerns, manufacturers have employed different methods to create inverted rubber with similar effects of speed glue.

However, if the opponent sends backspin, the spin is again returned but will be topspin to the opponent which can cause confusion as inverted rubber or short pips rubber would return backspin for the same stroke.

[3] Choosing the right table tennis rubber can be a complex process due to the various factors players must consider, such as playing style, speed, spin, and control.

Traditionally, players often seek professional advice by visiting specialized table tennis shops, where experts can guide them through the selection process.

These shops offer a hands-on experience and tailored advice, which is invaluable for both novice and experienced players.
