<p>PURPOSE:To obtain a regenerated fluororubber usable at a high temperature without causing hardening, and having excellent properties, by treating a fluororubber with an amine, and stirring and washing the treated rubber in a solvent capable of swelling the fluororubber or reacting with the amine. CONSTITUTION:Crushed waste fluororubber is treated with an amine, and stirred and washed in a solvent capable of swelling the fluororubber (preferably an organic solvent such as alcohol, ketone, ester, ether, cyclohexanone, etc., organic acid, or water) or a solvent reactive with the amine (preferably ketone or organic acid). The amount of solvent for washing the rubber is preferably 2-3pts.wt. per 1pt. of the rubber.</p> |
