Besides, canoe, kayak, lacrosse, snow shoes, moccasins, bow & arrow, toboggans, corn and pumpkins, I found this:http://www.nativeministries.com/article.php?id=771 RUBBER PRODUCTS: Native Americans made rubber products as early as 1700 BC. The Olmec and later the Maya would collect the sap from rubber trees (Hevea brasiliensis) to produce many rubber products. They also understood the process of vulcanization used in waterproofing such items as capes, shoes, bottles, tarpaulins, ponchos, baskets, and also used in making rubber balls. A rubber ball has been found at the Olmec site of La Venta dated to 1000 B.C. This process would not be discover by the European counterparts until Charles Goodyear discovered vulcanization and patented it in 1844. The Olmec became so identified with rubber that they became known as the "Rubber People". For more information see, "Encyclopedia of American Indian Contributions to the World" by Emory Dean Keoke and Kay Marie Porterfield, under the heading Latex.2) FREEZE-DRYING: As early as AD 1000 Native Americans were using the process of freeze-drying. It is basically the same process that is used today in making such foods as instant mashed potatoes. By freeze-drying the shelf life of the product could be extended into years instead of weeks. Although the Inca used this technique on a number of vegetables it was used mostly to preserve their surplus potatoes. For more information see, "Encyclopedia of American Indian Contributions to the World" by Emory Dean Keoke and Kay Marie Porterfield under freeze-drying.
United States Rubber Company was created in 1892.
Keds is a brand of canvas shoe with rubber soles, introduced in 1916 by U.S. Rubber.
Vulcanized Rubber can cost anywhere from one dollar to twenty dollars by the sheet. There are also vulcanized rubber molds you can purchase that range around twenty five dollars.
Rubber for factories in the U.S. was heavily dependent upon imports from countries such as Malaysia, Indonesia, and Thailand, which were the leading producers of natural rubber. The reliance on these imports was particularly pronounced during the 20th century, especially during World War II when domestic production was insufficient to meet demand. Synthetic rubber also became an alternative during this time, but the U.S. continued to depend on natural rubber from these key Southeast Asian countries for many industrial applications.
Charles Goodyear.
Vulcanization was discovered by Thomas Hancock from England in 1845; in US the first was Charles Goodyear also in 1845, but after Hancock. The subsequent claims of Goodyear (a discovery from 1839) were no longer taken into account.
vulcanization process of rubber and vulcanization process of rubber.
The inventor of vulcanized rubber, which is rubber that doesn't melt or freeze easily, was Charles Goodyear. He discovered the process of vulcanization in 1839 by mixing rubber with sulfur and applying heat. This process made rubber more durable and suitable for a wider range of applications.
the Goodyear brothers invented vulcanization of rubber.
vulcanization
Vulcanization.
yes definitly tools
latex from rubber trees is mixed with sulfur during vulcanization process
He didn't invent vulcanization of rubber. He discovered it in 1839 and patented the process on June 15, 1844. However, there is credible evidence that the Mesoamericans may also have used this process to make stable rubber for use as rubber balls in around 1600 B.C.
Sulphur, in a process called vulcanization.
Sulfur is commonly used as the element for hardening rubber through a process called vulcanization. It creates cross-links between rubber polymer chains, making the material more durable, elastic, and resistant to heat and wear.
