Same is Apollo rubber.
Be aware, the great tackiness of topsheet will produce less spin. Konrad Tiefenbacher, a sport engineer of Germany, proved this effect back in 1980s.

THREE SECRETS OF CHINESE GRIPPY RUBBERs.

Actually, Chinese rubber manufacturers have developed three different technologies for producing table tennis rubber sheets with tacky surface. Very specific technologies, very intricate machinery in use.

1) As is a common knowledge with all table tennis folks, table tennis rubber must be durable and elastic to project the ball forcefully, and the smooth surface must be grippy to better spin the ball. Back in 1972, Tianjin Friendship factory presented a novelty rubber material producing a really tacky feeling to the touch. And the Europeans can't make the such so far.
The most popular technology to produce stickiness on rubber surface makes use of the effect of "incomplete vulcanization". The whole of rubber piece is heated to 120*Celsius while the outer side is only heated to 70*Celsius. Thus, the external surface of rubber sheet (a thinnest layer of hundredths of a millimeter) retains much similarity to a raw rubber material, i.e. it is very and very sticky.
The disadvantage of this technology is obvious. The stickiness fades as the outer layer wears out. For example, Hurricane DHS rubbers.

2) 29-06-2020 12:20:00
Another Chinese rubber technology is using special rubber blendings to which liquid Nitrosamines are introduced. This method was first invented by the American engineer Henry Fischer in 1934.
Fischer's rubbers are easy to discern just by sniffing -- it would deliver a loud smell of rotten fish and the pimples inside would be as sticky as the outer surface of the sheet. The best pleasure you get with Fischer's rubber -- the grippiness is never to fade.   Double Fish manufacturer of China is now employing Fischer's Formula in making many rubber products of their own.

3) and finally, the most ingenious Chinese technology is a two-layer topsheet, where the outer layer is made of sticky silicone. An innovation of dubious legality that does not comply with the ITTF rules at all. Just purchase a sample and tear off the outer layer of silicon material. See the photo.

PS// The old good wisdom is just in place here:

If players obeyed the rules, you would still play hard bat with pimples out. Innovations never originated from ittf, they came from players.
