Properties of model rubber compounds with different vulcanization activators

Abstract

Influence of various vulcanization activators on properties of unfilled elastomeric compositions based on synthetic polyisoprene and oil-extended butadiene-styrene rubbers is investigated. Plastoelastic and relaxation properties, and also scorching resistance and kinetics of curing of rubber mixes with traditional and composite vulcanization activators are defined. As the composite vulcanization activator “Vulkativ-FC” was used. Its feature is the lowered content of zinc oxide and presence in the composition saturated fatty acids. The correlation of elastic and strength properties of vulcanizates with type and containing of the applied activator is established.
