VULCANIZABLE COMPOSITIONS BASED ON ELASTOMERIC COPOLYMERS OF VINYLIDENE FLUORIDE, VULCANIZATION PROCESS EOF AND VULCANIZED COMPOSITIONS THUS OBTAINED |
摘要 |
Vulcanizable compositions of vinylidene fluoride copolymer elastomers, a process for the vulcanization thereof, and vulcanizates produced thereby. The vulcanizable compositions comprise, in addition to the elastomeric fluoride copolymer, an inorganic acid acceptor, a basic compound, a polyhydroxy or polythiol vulcanizing agent, and a phosphorus complex compound additive. The presence of the phosphorus complex additive facilitates satisfactory vulcanization rates without scorching. The vulcanized fluorinated elastomers produced therefrom may be used as gaskets for sealing purposes and as protective layers in contact with corrosive chemical agents. They are particularly useful in applications such as sealing gaskets requiring strong adhesion to metallic surfaces even under severe temperature conditions. |
