主权项

1. A process for the processing of a perfluoropolymer material, the process comprising the steps of:
i) Dissolving one or more uncured perfluoropolymer materials in a solvent containing one or more liquid perfluorinated solvent(s) to form a solution; ii) Optionally adding one or more porogens and/or one or more functional additives to the solution formed in (i) to form a mixture; iii) Applying the resultant solution or mixture formed in steps (i) and (ii) to a substrate to form one or more partial or continuous deposited layers on the substrate; iv) Applying an amount of energy to the substrate or the one or more deposited layers to at least partially remove the solvent from the one or more deposited layers; and v) Curing the perfluoropolymer within the deposited layer to form a perfluoroelastomeric product. vi) Optionally removing the porogen from the perfluoroelastomeric product.
