Within the Absorbable Sealing Medical Glue market, product taxonomy is divided into two core types: polymer‑based adhesives and protein‑based sealants. Polymer‑based adhesives, comprising cyanoacrylate derivatives and synthetic polyesters, dominate with roughly 60 % of unit volume because of their predictable degradation kinetics and broad regulatory acceptance across multiple specialties. These formulations are further sub‑categorized into single‑component and dual‑component systems, each offering distinct handling characteristics and cure times. Protein‑based sealants, primarily derived from fibrin or gelatin, occupy the remaining 40 % and are favoured in applications demanding intrinsic biocompatibility, such as organ surface sealing and microsurgical repair. Sub‑types include fibrin‑derived glues, which provide a physiological clotting cascade, and gelatin‑based matrices that swell to fill irregular defects. The relative pricing, shelf‑life, and regulatory pathways of these types shape procurement decisions, thereby influencing the overall market size through differentiated adoption rates across clinical settings.
