SEIVIO Vaculub G352 low dust-generating high vacuum grease is based on micro-filtered linear perfluoropolyether oil (PFPE) and is thickened through a special process using special polytetrafluoroethylene (PTFE) powder with an average particle size of <0.8 microns. During the deep processing process, impurities such as volatile and low molecular weight as well as trace metal elements and compounds that are prone to pollution reactions are removed, making it capable of operating in extreme environments such as ultra-high vacuum, clean rooms, and high radioactivity. It is specially developed for dual-sensitive scenarios of high vacuum and cleanliness. The core is to meet the low volatility requirements of the vacuum environment while generating extremely low dust, and to avoid particles and volatiles from contaminating precision workpieces.
