Racket covering black technology: “Osmose Inverse” technology adhesive for the tradition racket covering is easy to be lossed because of the oxidation reaction between tradition adhesive molecule and sunshine, air and water. While the chemical state of the new adhesive molecule is very stable and not easy to be lossed. Moreover, “Osmose Inverse” technology can make the new adhesive molecule store inside of the rubber not outside of the surface as traditional technology. Under the premise of the loss of rubber surface, the ne adhesive molecule can release supplement by themselves, and make sure the rubber surface keep the durable adhesive
With Double Fish new patent technology “Osmose Inverse” QIJI rubber contains “new viscosity molecular”, which will maintain the stickiness of rubber surface. Using fully foaming (sponge cake), this flexible rubber can create fully shape changing, same time fast recover and high resilience, which comes out with powerful loop drive.
