Vulcanizing agent history
Natural rubber was being used in tire industry until 1839. Natural rubber had some problems, for example, it wasn’t durable enough and wouldn’t work properly under harsh conditions. Natural rubber becomes sticky or melts in high temperature and when it gets cold, it becomes brittle. IN 1839 Charles Goodyear, the founder of Goodyear tire company which is one of the first tire manufacturers in the world invented the vulcanizing agent to perform vulcanization process on rubbers. He actually named it Vulcanization after Vulcan, God of fire in Roman mythology. Sulfur is used in tires along other materials such as antiozonant wax to give more durability to it.
