Technology for industrial lubricants

Silicone lubricants

Silicone lubricants, either silicone greases or silicone oils, are a category of lubricants that exhibit properties of low attrition and high resistance to oxidation and moisture.

Introduction

Silicone lubricants can be formulated in different forms, such as lubricating greases, compounds, dispersions or pastes. In particular, phenyl silicones are distinguished by their ability to maintain their performance in low-temperature applications down to about -73°C and are often used for bearing lubrication under extreme conditions. Other types of silicones can be formulated into compounds used for lubricating rubber or plastic in static or dynamic applications.
