Hancock claimed to have invented vulcanization independently, and received a British patent, initiated in 1843, but finalized in 1844. In 1855, in the last of three patent disputes with fellow British rubber pioneer, Stephen Moulton, Hancock's patent was challenged with the claim that Hancock had copied Goodyear. Goodyear attended the trial.
Goodyear's patented machine for making vulcanized rubber fabric. Charles Goodyear invented a process for "vulcanizing" rubber by heating it to a high temperature in the presence of sulfur and lead carbonate or another chemical, so that it was converted from a soft, sticky, gummy product (so-called India rubber) to a hard, resilient, elastic, flexible product (so-called vulcanized rubber).
Worker placing a tire in a mold before vulcanization. Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. [1] The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic ...
Thomas Hancock patents the vulcanization of rubber in Britain immediately followed by Charles Goodyear in United States. [3] 1856: Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869

The discovery of the rubber vulcanization process is disputed. Some contest that it was invented by Charles Goodyear in America 1839, and patented in 1844. [13] Other accounts attribute it to Thomas Hancock in Britain in 1843. [14]

The discovery of the process to vulcanize rubber was made by Charles Goodyear in 1838, and was granted a US patent in 1844. Vulcanization stabilized the rubber, making it durable and flexible. In late 1843, Thomas Hancock filed for a UK patent, which was also granted in 1844, after the Goodyear Tire and Rubber Company patent had been granted ...
