Abstract
The invention pertains to a process for cryogenic milling mixtures of (per)fluoroelastomers and semicrystalline thermoplastic VDF polymers, and to free-flowing micronized pellets obtainable therefrom, said micronized pellets advantageously yielding, after extrusion and compounding, excellent mechanical properties, even improved over those of base fluoroelastomer matrix.
Claims20
A process for manufacturing micronized pellets of a (per)fluoroelastomer composition, said process comprising milling a composition comprising at least one (per)fluoroelastomer (A) and at least one thermoplastic semicrystalline vinylidene fluoride polymer (F) at a temperature below glass transition temperature of said (per)fluoroelastomer.
