Metal Forming Lubricants

We offer an array of task-specific products for the full spectrum of drawing and stamping processes. Our applications include componentry for the agriculture, medical, appliance, automotive, aviation and marine industries. Despite the complex and multifaceted nature of die stamping and metal drawing, Sun Chem’s century of expertise ensures that you will receive the appropriate lubricant for your requirements.



High Temperature Greases

Greases for very high temperatures (VHT) or Ultra High Temperatures (UHT) can be used in service at continuous temperatures ≥200°C and can withstand peaks of 300°C. These conditions require special chemistries, very different from traditional mineral greases.

Description
Lubrication at temperatures >200°C is very often poorly controlled. Use of traditional or even synthetic greases is not enough, or requires almost daily topping up. To resist decomposition or strong evaporation of the base oils at these extreme temperatures, the solution is to employ non-conventional chemistries. The thickener should be infusible or show a dropping point close to 300°C.

Very High Temperature VHT greases thus conserve sufficient viscosity to effectively lubricate the mechanical elements.

Under still more extreme conditions, it is preferable to use pastes highly charged with solids (graphite, copper, zinc,…). The grease is thus only a vector to give a uniform deposit of a dry lubricant to protect the
