SULPHUR-FREE EXPANDING AND HEAT-CURING RUBBER MOULDINGS

摘要

Hot hardening, expanding shaped parts based on solid polybutadiene rubber and vulcanization systems, free from elementary sulphur and characterized by the following advantageous properties: when delivered in a non-hardened state said preforms have only a slight rubber elastic restoring force and are easily deformable; no unpleasant odours occur during the hardening process, and a soft elastic foam with a closed skin is formed when used in a hardened state.
