Superabsorbent polymers can be used as a food packaging material and fresh-keeping material, and the preservation effect is much better than that of a polypropylene film. For example, it is used as a backing pad for meat foods to prevent liquid from flowing out when taken out of the bag. Because SAP absorbs water and does not absorb oil and non-polar substances, it can be used in oil-water separating agents, fire extinguishing agents, fire-extinguishing cloths, and durable alkaline batteries. SAP is used in papermaking to improve paper quality and reduce costs. In textile printing and dyeing, a certain degree of moisture can be maintained to prevent static electricity. SAP can be used as a leak-proof agent for fiber-optic cables. It can be directly covered with a high-absorbent resin or made into a bag-covered cable to prevent water from invading the cable. At present, the application of power cables and communication cables is expanding, especially in the field of fiber optic cables.
