Description
Radiation-thermal resistant greases were developed, using pentaphenyl ether (5P4E) and mono-alkyltetraphenyl ether (R-4P) for base oil and bentonite (B) for thickeners. The radiation-thermal resistance of the greases were evaluated by measuring changes in penetration, oil separation, weight loss (amount of volatilized and/or evaporated base oil), and molecular weight of base oil after irradiation with γ-rays at high temperatures (125, 150, 175 and 200degC). The greases showed excellent stability against both radiation and high temperature, and was found usable under the condition up to 4 MGy at 150degC. (author)
