e. Fluoro-elastomers (e.g. Viton ®, Tecnoflon ®)

Methods of curing such fluoroelastomer compositions and articles made from such fluoroelastomers are also provided.

Fluoro-elastomers (e.g. Viton ®, Tecnoflon ®

Provided are curable fluoroelastomers.

The fluoroelastomer compositions contain at least 23.4 mole percent hexafluoropropylene.

Such fluoroelastomers may be vulcanized with polyhydroxy curing agents.

Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile-containing cure site monomer are cured with certain carbazates.

Such fluoroelastomers may be vulcanized with polyhydroxy curatives.

Made from fluoroelastomers containing at least one vinylether group as a constitutional unit; and

This composition can give products of crosslinking of fluoroelastomers excellent in heat resistance and chemical resistances including steam resistance, and can provide crosslinkable fluoroelastomer compositions excellent in processability.

Made from fluoroelastomers containing at least one vinylether group as a constitutional unit; and

The compositions provide for a method of improving scorch safety of curable fluoroelastomer compositions.

Made from fluoroelastomers containing at least one vinylether group as a constitutional unit; and

Compositions and techniques useful to effectively recycle cross-linked (i.e., vulcanized or cured) fluoroelastomers are disclosed.

Optionally, the fluoroelastomers may be dual cured by both a polyhydroxy system and an organic peroxide system.
