Product Overview
Description
Water absorbing expansion bags are a new type of flood control product that is widely recognized by users due to its superior performance and convenient use. They have been widely used in Europe, America, Japan, and other places. The only layer of the water absorbing expansion bag is made of four in one ultrasonic polypropylene non-woven fabric with high water permeability, which has strong adhesion and good waterproof effect. The inner core is a polymer material with efficient water absorption and high water retention performance, endowing the water absorbing expansion bag with strong water absorption ability. Compared with traditional water absorbent materials, they expand rapidly after absorbing water and form gel, which is difficult to flow under external pressure, showing excellent water retention performance. They also have stable structure, good biocompatibility, and are insoluble in water and organic solvents.
