evaporation loss

Exposure of a grease to high temperatures can cause evaporation of some of the liquid lubricant, thus causing the remaining grease to become drier and stiffer or leading to other undesirable changes in the grease structure. Greases containing low-viscosity oils for good low-temperature performance may be susceptible to evaporation losses at higher temperatures. Evaporation also can cause problems where vapors may be hazardous or combustible, or interfere with operations. in most applications, even high-temperature applications, evaporation is not a serious problem because of effective sealing.
