Repsol's new sustainable process oil for tires: Bioextensoil
Repsol wants to be a part of the solution to climate change, helping customers to achieve their sustainability goals. We have developed a new line of sustainable oils: Bioextensoil, a 100% bio-origin oil coming from biorefinery by-products. Tread tire S-SBR/BR was extended with Bioextensoil and its performance was compared with S-SBR extended with conventional oils: TDAE, RAE and naphthenic. The vulcanization process, mechanical properties, mechano-dynamic properties and Payne effect have all been studied. The results show a high plasticizing effect and excellent performance at very low temperatures. Repsol sustainable oil, Bioextensoil, is an interesting option for tire rubber formulations, with good prospects for winter tires.
