Yasaka Zap Biotech 36-38
Rubber description:
This is a hybrid rubber characterized by a medium-hard, non-elastic top sheet paired with a moderately firm sponge. It features a slightly tacky surface that provides decent grip, though it requires active engagement of the sponge to maximize spin production. It is primarily functional for technical fundamentals, excelling in controlled movements such as serving, pushing, flicking, and controlled brush looping rather than high-speed offensive exchanges.
Playing Characteristics
- Spin and Speed: The rubber requires significant physical effort to generate high levels of speed and spin, as the lack of elasticity in the topsheet limits its performance in mid-distance rallies.
- Feel and Dwell: The rubber provides a firm, solid feel. The combination of a hard topsheet and a Biotech sponge results in a stiff contact, necessitating a high-impact stroke to compress the sponge and achieve a proper grip on the ball.
- Suitability: Due to its predictable, lower-rebound nature, it is well-suited for repetitive training drills and developing backhand stroke patterns.
Durability and Quality
- Consistency: As a budget-oriented Chinese rubber, it exhibits notable variability in production. Issues regarding surface consistency and sponge thickness can occur, and the level of tackiness may differ between individual sheets.
- Longevity: The surface grip is prone to degradation over time, and the rubber’s performance is generally considered better suited for practice environments than for high-level competitive match play.

This table tennis rubber is easy to use and offers more control than many others on the market. Players, regardless of their skill level, will find it intuitive and comfortable. The enhanced grip allows for precise ball placement, making it an excellent choice for both casual and competitive play.

This rubber is nothing special; you get what you pay for.
It is totally adequate for training purposes, whether using a robot or drills. However, it is not something one would want to rely on during games.
The rubber has a medium-hard feel and offers some grip on the top sheet. The sponge is marked as 36-38 Biotech (made by Palio) but feels somewhat harder. Additionally, the top sheet is also firm, in contrast to the CJ8000. The smell is fairly strong when removed from the vacuum-sealed package.
In terms of spin and speed, this rubber does not compare well with modern options. You will need to put in considerable effort to generate speed or spin.
Quality control is somewhat lacking, which I believe is typical of Palio-produced rubbers. While many people complain about DHS and their quality control, I personally find Palio to be miles behind DHS in this aspect. Occasionally, I noticed the pips were misaligned or too far apart (this was only on the red sheet, as I cannot see through the black one), along with issues related to sponge thickness and more. Furthermore, the rubber tends to lose its grip relatively quickly.
I do not want to completely dismiss this rubber; it is an acceptable option for the price. It is good for training, reasonably inexpensive, and lasts about a month (sometimes even less). It can serve as a decent choice for a first paddle or a training paddle.
Have fun and enjoy playing table tennis!

This is a good rubber for the price.
It performs best in serving, pushing, flicking, and brush looping. The surface is hard and durable; however, it is not very elastic. It is slightly tacky and becomes very grippy when the ball makes contact. Like other inexpensive Chinese rubbers, the grip can fail at times, especially during mid-distance attacks, serving, and pushing. To achieve the right grip, it is essential to engage the sponge properly due to the hard surface and limited elasticity.
The hybrid nature of the rubber, which is slightly tacky and grippy, offers a wide range of spin possibilities, making it quite effective for serves and serve returns.
One thing to note is that one sheet can be tackier than another, even when they are the same color. However, this is a common issue with Chinese rubbers.
In terms of durability, I have found this rubber to outlast Sriver rubbers. In my experience, Sriver rubber becomes too bouncy after about three months, even with only a couple of practice sessions each week (this was approximately five years ago). Additionally, Sriver tends to lose its grip too quickly. In contrast, Zap seems to have a much longer lifespan.
I have also tried Sriver FX and EL on a Donic Persson Powerplay, but this does not provide much insight into how the rubber’s surface bounces. Even when I used it on a much slower blade, I did not achieve better results; the rubber simply wore out.
Recently, I tested Zap 36-38 biotech on Blue Thunder 550 and 555 blades.
