👉 A gel fluid is a semi-solid, viscous substance that exhibits properties of both liquids and solids. It is composed primarily of a polymer network or long-chain molecules that are entangled, giving it a structure similar to a gel but with a higher degree of cross-linking compared to a typical gel. This network traps liquid within its structure, making gel fluids neither entirely fluid nor solid; they can flow like a liquid but also retain their shape and resist deformation like a solid. This unique combination of characteristics makes gel fluids useful in various applications, including medical devices, cosmetics, and industrial processes, where their ability to maintain form while allowing for some flexibility is highly beneficial.
