New Class of Overbased Sulfonate Grease Fortified with Alkylated Naphthalene Base Oil for Superior High Temperature Rheological Stability
Overbased Calcium Sulfonate (OBCS) Grease has received growing attention in recent years, especially in the North American Market. Its production has grown more than three folds from 1.3% in 2009 to 5.4% in 2012, according to a recent NLGI survey. Today, despite a great deal being known about how to produce good quality OBCS grease, its production remains in the hands of only a few grease manufacturers.
