The Effect of protein content in natural rubber on performance of silica filled compounds as influenced by processing temperature
Material type:
TextPublication details: Kautschuk Gummi Kunststoffe 2013Description: 27-33Subject(s): Summary: The use of a bi-functional silane coupling agent enhances the interaction between silica and apolar rubbers such as Natural Rubber (NR). 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.
