SEIVIO Vaculub X189 Semiconductor Clean Room High Vacuum Grease is based on micro-filtered linear perfluoropolyether oil (PFPE) and is thickened by a special process using special polytetrafluoroethylene (PTFE) powder with an average particle size of <0.8 microns. This product optimizes the production process and reduces the risk of volatilization through baking and pre-extraction. It has low gas release rate and low dust generation characteristics. It perfectly solves the problems of grease volatilization and particle release under vacuum and high temperature. It is a grease for semiconductor equipment with excellent comprehensive performance.
