Versatile, one‑component polyurethane binders designed to bond a wide range of substrates—including flexible foams, recycled materials, and mixed particulate systems—into durable composite products. These binders are combined with materials such as foam scrap, EVA, cork, gravel, or other aggregates and cured to form cohesive structures. Compared with alternative binding technologies, they offer broad substrate compatibility, efficient processing, and balanced mechanical performance, enabling the creation of high‑value products from diverse and recycled inputs. Chemical type: Polyurethane (PU) binder Chemical name: Isocyanate‑terminated polyurethane prepolymer CAS number: Mixture
