The scientific name for bubble beads is super absorbent resin. Super absorbent resin is a newly developed functional polymer material that contains strong hydrophilic groups and has a certain degree of cross-linking. These resins are insoluble in water and organic solvents. They can absorb hundreds or even thousands of times their own weight in water and are very water-retaining. Even if the water is under pressure, it will not be discharged.
For example, starch-grafted acrylates, highly substituted cross-linked carboxymethylcellulose, cross-linked hydroxyethylcellulose-grafted acrylamide polymer, etc., can generally absorb the equivalent of 100% of the volume of resin. humidity, the highest water absorption rate can reach more than 1,000 times. It is usually used as medical material, such as diapers, sanitary napkins, etc., and is also used as leak-proof materiale in the industry.
Detailed information
Uses of super absorbent resin:
Water absorbent polymer resin is a non-toxic polymerization of networked polymers. It has strong water absorption properties.
1. Medical and health care: sanitary napkins, changing mats, diapers, medical mattresses, absorbent paper, extended release medications, ointments, water bags, etc.
2. Agriculture and gardening: seed coating, seed treatment and seedling cultivation.
3. Industry: water-resistant expanding rubber, water-absorbing antifouling paint, anti-static paint, oil field water blocking and oil-water separation, optical cables
Resistant tape and cable paste , waiting for concrete maintenance.
4. Water absorbent for the food industry, preservative for fruits and vegetables.

Oceanic ball (Marine Ball) is a product for baby play areas, naughty castles and outdoor activities, etc., which can bring wisdom and fun to babies. It is made from environmentally friendly PE material and does not add chemicals (fluorescent agents) to ensure the baby's safety and no harm to the baby. When choosing, look for balls that are odorless, burr-free, and have smooth edges. Bring wisdom and fun to babies. The ocean ball adopts two-step non-porous blow molding technology.
Practical
1. The ocean ball adopts two-step non-porous blow molding technology.
2. Bobo balls have pores, but the pores are all in the mold! The pore distribution is very small!
3. During the pro processduction, plastic begins to melt at high temperatures of several hundred degrees. When it flows into the mold cup, it instantly closes the mold, instantly blows air and opens the mold [1] and naturally forms a sphere. shape!
4. If you are a careful friend, if you look closely at the surface of the bullet, there are still traces of tiny ejection holes! However, this does not affect product safety. The products have been strictly tested. It can be said that a 60 kg adult will not break while standing on the ball!
5. In order to allow the ball to have sufficient air pressure, it is recommended to use a pneumatic screw press!
