👉 In a context of materials science and engineering, "pre-absorbent" refers to a material that is used as an intermediate in the process of forming a polymer, which can be further processed into various products. Pre-absorbents are typically used for the production of synthetic polymers, such as plastics, rubber, or fibers. Pre-absorbents are often characterized by their high degree of stability and resistance to degradation during processing. They are typically made from natural materials like cellulose, lignin
