Abstract

Heat-curing, expanding mouldings based on solid polybutadiene rubber and vulcanization systems free from elemental sulfur are distinguished by the following advantageous properties: in the uncured state in which they are supplied, they have minimal rubber-elastic resilience and are readily formable. During the curing process, no unpleasant odors are given off and, after curing, a soft and elastic foam with a continuous outer skin is formed.
