Do not use this more than two years

User echo after the purchase of a cap made this a bit worried: the hat so cheap, the materials used will not harmful?

For this problem, Beijing University of Technology, Associate Professor of Materials Science and Engineering, said Li Haihua, this new york hats in use mostly absorbent gel. Any water-soluble or hydrophilic polymer, through a certain chemical or physical cross-linking cross-linked, can form a hydrogel. Specifically, may be polyoxyethylene, polyethylene glycol, or other gel-type substances. These gel-type substances generally unlikely to cause harm, but use a long time after the degradation of these substances may produce harmful small molecules.

It is proposed to use such materials for no more than two years.
