Properties: when the temperature is lower than the phase transition temperature, the polymer can be dissolved in water to form a free flowing liquid. When the temperature rises above the phase transition temperature, the aqueous solution of the polymer will undergo phase change to form a non chemically crosslinked gel, and the process of forming a gel is reversible. When the temperature drops, the gel solution transition can occur.

Warm tip: in order to obtain the best use effect of the product, the material should always be kept at a low temperature under dry conditions to avoid frequent thawing and freezing. In order to ensure the stability of the product, please pay attention to opening the package for use after drying at a constant temperature!
