The paper focusses on the influences of non-rubber constituents such as proteins on the properties of silica-filled NR compounds at varying mixing dump temperatures. The work demonstrates that when high amounts of proteins are present in NR, modification of the silica surface by silane is partially hindered. The rheological properties, Payne effect and rubber to filler interactions as well as physical properties of silica reinforced NR at varying protein contents with silane coupling agent are discussed ER -
