X-FACTOR is a top-tier professional forehand rubber, designed with Epsilon sponge and advanced X-Factor technology, delivering perfect ball contact, exceptional stability, and optimal control. The AI-optimized C57.5 version features a thicker top layer, shorter and more compact micro-pore arrangement, and an improved tacky surface, providing an intuitive feel with every stroke.
The Epsilon sponge, with its innovative distribution of air bubbles, ensures effective energy transfer on shots even at distance, while the advanced NIF technology adds ultra-slow elasticity for precise control near the net. Digitally developed technologies ELASTRO FUTURA, CYCLOID, and DYNAMIC FRICTION increase spin and speed, enable an optimal spin–distance range, and greater tolerance across different strokes.
The rubber is ideal for aggressive players who want a combination of control, speed, and top rotation. Suitable for both professionals and top recreational players who want to exploit the benefits of advanced AI technologies in modern table tennis.

This technology was enabled by artificial intelligence. Chinese gluable rubber offers great control on short distances because of its hard sponge and gluable surface. But the use of this rubber weakens the balls, hit far away from the table. To replace these deficiencies, players use amplifiers, that strengthen the rubbers tension at strikes from a distance.
The so named 'FACTOR X' is the key factor of the Chinese dominance over table tennis. February of 2024 the ITTF introduced regulation for gradual prohibition of amplifier use. They developed Jekyll & Hyde C55.0. This is the first rubber with double tension (dual tension) with X-Factor, which doesn’t need the booster of dual tension because it is already integrated. This was enabled by the use of artificial intelligence.
Inside the Epsilon sponge, our new technology for sponge making, are bubbles smaller and evenly distributed.
The success of Hugo Caldera has highly improved, since when he became the first non-Chinese player, that switched to C55 with X-FACTOR rubber on both sides of the board.
New development platform DEEP LEARNING. CYCLOID is innovative methodology, which enables the development of rubbers in a DEEP LEARNING way. With this methodology we can develop rubbers, for witch its more likely, to allow success in offense and defense.
The trajectory of the ball is significantly larger. Not only have the blocks at the net decreased, but the balls also land deeper towards the edge of the table without falling out.
The speed increases with new calculated ratio between rotation and distance, and it gives more powerful advantages to speed. New dynamic energy allows the ball at topspin to gain more power and create new opportunities for winning.

Is a new technology that enables better grip of plastic balls. Because the new balls have great rebound, but a much more slippery surface, making them decently harder to control.
That is why they developed Dynamic Friction technology, used for winter tires that allows for an optimal grip.

The newest technology of the upper layer and sponge, optimized for ball speed. Experience the new improved elasticity of the rubber.
ELASTRO FUTURA – new era of artificial intelligence
Digital methodology CYCLOID, that is based on the new technology of artificial intelligence, mechanism DYNAMIC FRICTION following snow tires and energy-efficient CARBO SPONGE are key forces that fuel the ELASTRO FUTURA generation. The most advanced technology of rubber production, supported by the platform for development of artificial intelligence, has recalibrated levels of rotation based on distance. New balances have been created in the science of table tennis rubbers.
