WebbThe results show that the grease produced with a minimum ratio of fumed silica to sludge (10:90) was high temperature grease with a dropping point of 272.5°C. Further analysis show that the grease produced is high temperature grease with a worked penetration of 270-290 which makes the grease fall into NLGI number of two.
