Â
It is designed for the bonding seal such as crank shaft seals and valve stem seals.
Â
Features of SF-361C are:
l          Excellent mold release
l          Excellent hot tear resistance
l          Excellent bonding performance
l          Good mold flow
Recommended Processing Procedures
SF-361C can be compounded with internal mixers or two-roll mills with standard fillers and other ingredients that are used in typical fluoroelastomer formulations. All the dry ingredients should be blended before adding to the rubbery solid. During compounding, full cooling should be accompanied. After mixing, the compound should be cooled as quickly as possible.
