Rubber vulcanisation creates chemical sulphur crosslinks between polymer chains

Heating natural rubber latex with sulphur yields heat-resistant elastic tyres

Natural rubber sap degrades easily, becoming sticky in heat and brittle in cold. In 1839, Charles Goodyear accidentally dropped a mixture of natural rubber latex and sulphur onto a hot stove. The process, called vulcanisation, created chemical crosslinks between polymer chains, yielding durable, elastic rubber for tyres.
