Abstract: Methods of making anti-sticking perfluorinated articles are described. The methods include molding curing, and heat-treating a composition prepared from a coagulated and dried blend of latex dispersions of a perfluoro-elastomeric gum and a perfluoroplastic. The curing steps are performed at temperatures below the melting point of the perfluoroplastic, while the heat-treatment step occurs at a temperature above this melting point. The resulting articles are also described.
