Detailed explanation-1: -Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.
Detailed explanation-2: -Charles Goodyear, (born Dec. 29, 1800, New Haven, Conn., U.S.-died July 1, 1860, New York City), American inventor of the vulcanization process that made possible the commercial use of rubber.
Detailed explanation-3: -While Charles Goodyear is credited with developing the process that made it possible to create rubber products, you can’t accurately discuss the history of rubber without mentioning early Mesoamerican people, 18th century English entrepreneurs or German and Russian chemists.
Detailed explanation-4: -Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
