Molybdenum disulfide grease, also known as moly grease, is a lubricant commonly used in automotive, industrial, and marine applications. It is composed of molybdenum disulfide, a synthetic oil, and a thickener. It is used as a lubricant for bearings, gears, and other high-load components. It is also used as an antiseize agent and to reduce friction in engines and transmissions.
When rubber is exposed to molybdenum disulfide grease, there can be a few common types of failure. As the molybdenum disulfide grease is a lubricant, it can cause rubber seals to slip and move out of place, leading to leaks. Additionally, the synthetic oil in the grease can cause the rubber to swell and become brittle, leading to cracking and eventual failure.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
