ABSTRACT:
A treatment for finely divided silica reinforcing fillers is provided which comprises heating the silica filler in the presence of a fluoroalkyl-functional diorganopolysiloxane. The treated fillers are especially compatible with fluorosilicone gums, and fluorosilicone rubbers made using said fillers exhibit improved mechanical properties, especially tear strength and compression set.
