These thioantimonites are used in the vulcanizing of rubber and in the preparation of matches.
Sulphur chloride dissolves sulphur with great readiness and is consequently used largely for vulcanizing rubber; it also dissolves chlorine.
Another method of vulcanizing articles made from cut sheet rubber consists in exposing them to the action of chloride of sulphur.
In order to make spongy or porous rubber, some material is incorporated which will give off gas or vapour at the vulcanizing temperature, - such as carbonate of ammonia, crystallized alum, and finely ground damp sawdust.
