Verfahren zur Regenerierung von vernetztem vulkanisiertem Fluorkautschuk und dessen Verwendung
Filler-containing, cross-linked, vulcanized fluorine rubber waste is regenerated by treatment with at least one of CH3SO3H, ClSO3H, CF3SO3H and fuming sulfuric acid, followed by dissoluting into a solvent and separating solvent-insoluble filler therefrom, whereby revulcanizable fluorine rubber is re...

description | Filler-containing, cross-linked, vulcanized fluorine rubber waste is regenerated by treatment with at least one of CH3SO3H, ClSO3H, CF3SO3H and fuming sulfuric acid, followed by dissoluting into a solvent and separating solvent-insoluble filler therefrom, whereby revulcanizable fluorine rubber is recovered from the fluorine rubber waste, almost irrespective of types of cross-linking systems used for formation of cross-linked, vulcanized fluorine rubber. |
