CORE/SHELL FLUOROPOLYMER COMPOSITIONS

Core/shell fluoropolymer compositions in particulate form, wherein the core is a highly crystalline polymer such as, for example, tetrafluoroethylene, and the shell is an elastomeric fluoropolymer such as, for example, a vinylidene fluoride/hexafluoropropene copolymer, optionally also containing a c...

Zusammenfassung:	Core/shell fluoropolymer compositions in particulate form, wherein the core is a highly crystalline polymer such as, for example, tetrafluoroethylene, and the shell is an elastomeric fluoropolymer such as, for example, a vinylidene fluoride/hexafluoropropene copolymer, optionally also containing a cure site monomer are outstanding additives for uncured fluoroelastomer compositions, which after curing in the presence of dispersed core/shell fluoropolymers have improved tear strength, tear strength to modulus ratio, and certain other physical properties.
