FIELD: chemistry.
SUBSTANCE: elastomeric composition for sealing materials based on a copolymer of tetrafluoroethylene and perfluoromethylvinyl ester and perfluoroalkyl vinyl esters which contain a cyano group, contains perfluorodiimidoyl amidine as a curing agent and further contains nano-sized nickel metal in the presence of a perfluorinated dispersant.
EFFECT: improved processability of rubber mixtures, vulcanisates have high nominal tensile strength, good physical and mechanical properties, resistance to nitric acid, high heat resistance after ageing for 70 hours.
