Justement j’étais en train de faire des recherches sur ce revêtement.

"A three year endeavor has settled into a beautiful harbor. As a Nexy brand manager who studied the history of two representative rubber producers, ESN factory in Germany and Butterfly in Japan, I concluded that a thinner column structure for the currently selling rubbers’ top sheet can be an attractive upgrade formula for the future of table tennis. And, I applied this methodology for the Japanese factory, which bore fruit of Karis. Karis was quite different from all other contemporary rubbers, and many found that this uniqueness facilitated better play. Still, I thought Karis was too different in comparison to the popular rubbers most players use. So, I began persuading Tibhar, Nexy’s life-long friend brand, to produce a Karis structure type rubber with ESN. It started three years ago, and today I have MX-K in hand. In order to spare you from searching my earlier articles to understand the reasons for this technical upgrade, I included the following summary, which explains how to make better rubbers out of ESN technology.
MX-K is a very strong rubber, inheriting every good thing about MX-P with some additional features.
•Weight: Compared with MX-P, MX-K is a little lighter without sacrificing any power.
•Gripping Power: With the unified movement of top sheet and sponge, MX-K works well close to the table as well as away from the table. You can especially feel an easy contact of the ball, even when you are not in the best position. This rubber is more forgiving and allows more flexibility.
•Steady Control: MX-P shows some unexpected movement when you are not hitting the ball with the correct swing movement. But with MX-K, you can feel easier control for all conditions.
•Harder Sponge Version: With MX-P, ESN might have had some difficulty releasing hard sponge rubbers, and it took many years until they release MX-P 50. However, with this new top sheet structure, we can easily produce a good rubber with harder sponge. MX-K H with 52.5 degree sponge is available! This is still very easy to play with and retains exceptional power.
MX-K is a Tibhar brand rubber, but all rubbers are to delivered to Korea, and Nexy headquarters will be selling to all countries. So, it’s almost a Nexy rubber, and I will regard this rubber as a representative for Nexy business. There could be some video files taped in Korea and in Germany, and I will provide those YouTube links"
