It's organic, of course.

Ping-pong is a racket.
Viscose glue is organic glue and inorganic glue, which is widely used.
1. The main components of organic glue are rubber molecules and organic solvents, and the rubber molecules left after sol volatilization are cross-linked into polymers to play a role in adhesion.
The proportion of organic solvents in the composition of glue is usually higher than that of rubber, and the commonly used organic solvent is cyclohexane.
Heptane, etc. This is also the current general glue, its market is much lower than inorganic glue, occupying a larger market.
2. The main ingredient of inorganic glue is inorganic.
adhesives, such as cyclohexane, which is now often used. The appearance of inorganic glue is colorless, tasteless, and clear as water. Inorganic glue is currently the most high, and it is necessary to use a sponge with a high reputation.
It is recommended to buy a bottle of special glue, other general glue is not sticky, you can stick it with 502, but your racket will be wasted.

1. The ingredients are different.
Organic glue is a glue made of natural rubber plus synthetic rubber, and then mixed with organic solvents; Inorganic glue refers to glue that contains no or less organic chemical components in the solvent, generally containing polyvinyl alcohol.
Sodium stearate, white latex, and a small amount of talcum powder.
and urea. Flavors and other ingredients are sold.
2. The taste is different.
Organic glue smells pungent; And inorganic glue has no taste.
3. The performance is different.
Due to the similar principle of organic glue, the glue containing organic matter can penetrate into the sponge of the racket to fill bubbles, so that the sea servant source cotton expands rapidly and increases the speed after hitting the ball; Inorganic glue will reduce the velocity after the shot.
4. The use time is different.
Organic glue is volatile and produces toxic gases, which have a negative impact on the athlete's body, so there will be a special place to stick the racket before the table tennis match; The old inorganic glue is non-toxic, and according to the decision of the International Table Tennis Federation, it will be held in the Beijing Olympics.
After the meeting, inorganic glue is always used.

Although organic glue is toxic, it should not be a big problem for the eyes, but it is harmful to the respiratory organs of people! Now the International Table Tennis Federation has banned the use of organic glue, just because it is toxic, but the racket sticky with organic glue is elastic and very comfortable to pull the ball. It is recommended that you still use inorganic glue, whether from the perspective of health or trend, it is best not to use organic glue.

Hello dear to table tennis competitions with inorganic glue At present, international table tennis competitions use inorganic glue. In the new ITTF (International Table Tennis Federation) rules implemented on May 1, 2015, the official rule is to replace the previously widely used water-based organic glue with water-based inorganic glue. The difference between inorganic glue and organic glue is that their composition is different.
Inorganic glue is mainly composed of cellulose silicate and the products of its secondary chemical treatment, such as crystal glue, as well as ethoxysilane glue, such as domestic Hebei Jialede table tennis glue. Organic glues, on the other hand, mainly use synthetic resins containing organic substances such as phenyl groups. The advantages of inorganic glue are that the adhesive force is durable and stable, the damage to the racket laminate is small, it is easy to clean with water, and it is also friendly to health and the environment.
Although organic glue has the advantage of strong adhesion, it has volatile harmful gases and damage to the rubber material on the racket, and long-term use may cause health effects on the human body. Therefore, inorganic glue has gradually become the mainstream of modern table tennis competitions.

Summary. Hello, if it is a table tennis match, the table tennis racket must be used with organic glue.
Hello, if it is a table tennis match, the table tennis racket must be used with organic glue.
Hello, the general table tennis game ball Zen socks are inorganic glue, and organic glue good land water has been banned by the International Table Tennis Federation, the main reason is that it is slightly toxic, and he Hong has a negative effect on the user. Due to the excellent swelling effect of organic glue, it is also widely used in the amateur world.
The characteristics of organic glue The main components of organic glue are rubber molecules and organic solvents, and the rubber molecules left after sol volatilization are cross-linked into polymers, which play a role in eliminating adhesion. The composition of glue is usually organic solvents. But this glue will only be used in amateur places.

The organic glue of table tennis is a volatile glue with low toxicity, which can cause harm to the human body, so it is forbidden to use it.
For the first time, the team competition system was introduced in the table tennis competition of the Beijing Olympic Games, and many rules were implemented for the first time.
