Answer:According to relevant sources,crosslinking agent is usually a "solvent like" substance that, when added to materials such as plastics, resins, or elastomers, can improve their processability, increase plasticity, flexibility, stretchability, or expansibility. Adding crosslinking agents can reduce the melt viscosity, glass transition temperature, and elastic modulus of plastics, without altering the basic chemical properties of the plasticized material. Its added objects include plastic, concrete, wall materials, cement, gypsum, and so on. The same crosslinking agent is often used on different objects, but its effect is often not the same.
