· JVASP-127507· MoS

MoS is a molybdenum sulfide compound that functions as a solid lubricant and catalytic material, valued for its layered crystal structure that provides inherently low friction and high shear strength between atomic planes. It is widely employed in aerospace bearings, high-temperature machinery, and industrial catalysis applications where conventional liquid lubricants fail or contamination must be minimized; engineers select it over alternatives because it performs effectively in vacuum, extreme temperatures, and corrosive environments without the maintenance burden of oil-based systems.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
