UPM BioMotion^TM RFF can be added directly during extrusion or as a masterbatch in extrusion or further processing of thermoplastic materials. Compounds containing UPM BioMotion^TM RFF at various loadings are suitable for all common processing technologies used in thermoplastic conversion like e.g., extrusion, injection molding, compression molding, blow molding, thermoforming, film blowing and 3D printing. Even at high filler loadings easy processing in extrusion, injection molding and other conversion methods is given up to temperatures of 260°C without the characteristic strong odor which is known from Kraft lignin.

During the processing and recycling of thermoplastics, UPM BioMotion^TM RFF offers several advantages. Thermoplastic materials containing UPM BioMotion^TM RFF exhibit excellent thermal stability in terms of melt flow index (MFI) and oxidation induction time (OIT). The MFI remains constant over a series of up to ten processing cycles while the OIT even increases. No color changes of the thermoplastic materials are observed. Thus, UPM BioMotion^TM RFF could potentially replace some of the additives typically used for thermal stabilization, especially in polyolefin processing.

Furthermore, UPM BioMotion^TM RFF can be used in unlimited amounts as an additive for industrial, home, soil, and marine biodegradable products (according to DIN EN 13432 and DIN EN ISO 224031). This opens possibilities for various biodegradable applications with increased renewable material content.
