Fluid Plasticizers Including Fluorinated Organic Compounds for Use in Curable Fluoropolymer Compositions and Fluoroelastomer Compositions, and Methods for Improving Processability and Low Temperature Use Properties of Such Compositions

Abstract

Curable fluorine-containing compositions and fluoroelastomer compositions are described herein that provide for reduction in viscosity and improvement in processability, as well as a lowering of a lowest use temperature of a fluoroelastomer by incorporating in such compositions a fluid plasticizer that includes at least one, at least partially fluorinated organic compound and that is capable of reducing viscosity and improving processability of a fluoroelastomer formed from a curable fluorine-containing polymer in comparison to a fluoroelastomer formed from the same curable fluorine-containing polymer without the at least one, at least partially fluorinated organic compound and/or that is capable of achieving a lowest use temperature of a fluoroelastomer formed from the curable fluorine-containing polymer that is lower than a lowest use temperature of a fluoroelastomer formed from the same curable fluorine-containing polymer without the at least one, at least partially fluorinated organic compound. Methods of improving processability and/or reducing viscosity and/or lowering the lowest use temperature of a fluoroelastomer are also described.
