Reactive extrusion is a process in which a reactive compound is combined with a polymeric material and then extruded through a die to form a product with unique properties. This type of extrusion is used to create products with specific chemical, physical, and mechanical properties that are not achievable with traditional extrusion processes. Reactive extrusion can involve the addition of cross-linking agents, catalysts, stabilizers, and other additives to the polymeric material in order to create the desired product.
