Abstract:

Seventeen greases were shear worked at ambient temperatures by three different shear methods. The approximate shear rates of these methods were 20sec., 450sec., and 10,000sec. The breakdown of the greases was evaluated by consistency changes as determined by the 14 scale worked penetration, ASTM Federal Test Method D-1403. It was found that the greases made with synthetic thickeners were usually more shear stable than those made with soap base thickeners. In a majority of greases the higher the rate of shear, the greater the breakdown. Author
