General explanation of natural rubber.

Rubber is the most important natural polymer and can be seen from the extensively used in industrial use. Rubber used for centuries by the virtual race western hemisphere before being introduced to Europe by Columbus. However, despite being introduced by Columbus, the term rubber actually created by Joseph Priestley when coutechouc notes that can be worn to remove the writing of the pencil. Since then, the term rubber from natural polymer is pinned on. Rubber is politerpen material will naturally synthesized via enzymatic polymerization isopentilpirofosfat.

In general, almost all natural rubber obtained as a latex made from rubber around 32-35 percent and about 5 percent of other compounds, including fatty acids, sugars, proteins, esters and salts. Including rubber polymer with very high molecular weight, and atmorfus, Although he was becoming crystallized randomly at low temperatures. When converted to a rubber latex foam with mechanical aeration process followed by vulcanization. Rubber gloves and latex balloons are usually made of one of the applications from utilizing rubber. Most latex coagulated using compounds (eg acetic acid) and applied in a compact form.



In addition, latex is a dispersion of polymer solution has a very small particle size, which measure about 60 to 1000 nanometers. Latex will live to be processed until the dispersed colloidal clusters where the rubber is going to be hard. For example, in the manufacture of latex base. In the other case will be controlled instability of latex liking. Latex particles that can lead to negative ion exchange called latex d with ionic mass, and particles that carry a positive ion exchange called mass cationic latex.

Thus, the use of rubber to date very much. One of them is used in the manufacture of tires but also can be found in a number of commercial products including footwear, rubber seals, electrical insulators, sports equipment and so forth.
