Rapeseed Oil (Bio-Based Rubber Extender)
Rapeseed oil is a bio-based, renewable process oil and extender used in rubber compounding as a sustainable alternative to mineral-based aromatic and naphthenic process oils. It provides good solvation of NR, SBR, and BR polymers, improves filler dispersion, and reduces compound viscosity. With growing demand for bio-content and eco-label tires, rapeseed oil is increasingly specified in green tire tread compounds to replace part of the mineral oil fraction.
