Compositions and techniques useful to effectively recycle crosslinked (i.e., vulcanized or cured) fluoroelastomers are disclosed. The invention utilizes an additive system that includes a cure-enhancing additive, a crosslinking agent, and an accelerator.

Recycle of vulcanized fluorinated elastomers

Fluorine-containing thermoplastic elastomeric compositions comprising: (A) a continuous phase comprising: (1) about 0 to 90 weight percent of thermoplastic polymer having a melt temperature or glass transition temperature greater than about 150.degree. C., and (2) about 10 to 100 weight percent of block thermoplastic elastomer having a melt temperature greater than about 150.degree. C.; and (B) a disperse phase comprising particles or domains of cured, fluoroelastomer composition. Such compositions are preferably prepared by dynamically vulcanizing the ingredients of the fluorine-containing thermoplastic elastomeric composition.

Polymer blend composition of fluorinated elastomers, thermoplastic

An elastomeric pre-stretched tubular member comprising from about 2.5 to about 25 volume percent carbon black, from about 0.8 to about 3.0 volume percent of platelet-shaped conductive particles, and optionally high permittivity inorganic fillers and platelet-shaped inorganic dielectric fillers, with the balance being the compounded elastomeric component.
