Abstract
Provided is a curable fluoropolymer composition comprising a fluoropolymer comprising interpolymerized units of tetrafluoroethylene, perfluoro(aliphatic vinyl)ether, and a nitrogen-containing cure site monomer; a catalyst to form cross-links with the nitrogen-containing cure site monomer; an organic peroxide; a co-agent to participate in a peroxide cure; and a hydrotalcite compound. Also provided is an article comprising the cured fluoropolymer reaction product of the curable composition and a method for forming a shaped article.
