  • Interesting fact: Heavyweight tire manufacturer Goodyear is in no way affiliated with Charles Goodyear, the inventor of vulcanized rubber. They merely admired his inventiveness and his process that was so easy to duplicate that competitors simply stole it.
    • n vulcanization A method of treating caoutchouc or india-rubber with some form of sulphur, to effect certain changes in its properties, and yield a soft (vulcanized india-rubber) or a hard (vulcauite) product. This was originally effected by dipping the rubber in melted sulphur and beating it to nearly: 300. Several other methods have been employed, probably the best of which for general purposes consists in mechanically mixing the rubber at a moderate heat with flowers of sulphur, and subsequently “curing” it in superheated steam at from 250 to 300 Fahr. The process was invented by Charles Goodyear, who obtained his first patent for it in 1844. Other ingredients, as litharge, white lead, zine-white, whiting, etc., are added to the sulphur to give color, softness, etc., to the rubber. The substance thus formed possesses the following properties: it remains elastic at all temperatures; it cannot be dissolved by the ordinary solvents, neither is it affected by heat within a considerable range of temperature; finally, it acquires extraordinary powers of resisting compression, with a great increase of strength and elasticity. Vulcanized india-rubber is employed with great success for very many useful purposes, as for waterproofing cloth, for boots, shoes, mats, toys, belting, buffers, wheel-tires, washers, valves, pipes, fire-hose, medical and surgical appliances, etc. Hard vulcanized rubber is known as ebonite or vulcanite. See vulcanite. Also spelled vulcanisation.
