Abstract

Heat-vulcanizable organopolysiloxane compositions well adopted for extrusion and molding, and facilely converted into elastomeric shaped articles having improved physical and electrical properties, e.g., seals and sections, include a diorganopolysiloxane oil containing from 0.05 to 3 mol % of vinylsiloxy recurring units, as well as an amine having a pKa greater than 7.5 in aqueous solution at 25.degree. C. and a boiling point of less than 270.degree. C. at atmospheric pressure.
