Natural rubber is made from latex which is taken from trees and is widely used in many products to this day. Synthetic rubber is preferable in most applications today due to the fact that it is more durable than natural rubber and the chances of allergic reactions are smaller.
Natural rubber, or gum rubber, is made from latex. A LOT of rubber available today is synthetic, made from petroleum. And a large amount of the gum rubber contains a percentage of synthetic rubber.

Rubber is made from extract of SAP tree Natural rubber, also called India rubber or caoutchouc, is an elastomer (an elastic hydrocarbon polymer) that was originally derived from latex, a milky colloid produced by some plants. The plants would be 'tapped', that is, an incision made into the bark of the tree and the latex sap collected and refined into a usable rubber. The purified form of natural rubber is the chemical polyisoprene, which can also be produced synthetically. Natural rubber is used extensively in many applications and products, as is synthetic rubber.
well they are a fossil fuel and they form over many and many of years
Foam? Like old coffee cups and such? They never biodegrade. Unlike plastic that will take a thousand years foam will never biodegrade. In ten millions years of something is digging in the ground, it could find your cup that you left behind.
If the question is in regard to the chemical symbol of rubber, rubber does not have a chemical symbol. This is because rubber is a chemical compound rather than a single chemical element. Many rubber compounds are hydrocarbons (composed of carbon and hydrogen), and there are many, many different rubber compounds. A general division of rubbers is that between natural rubber and synthetic rubber, and these have been developed over years to suit a wide variety of applications.
Yes, rubber has been in trade for many years. The white sap from the bark of the Hevea tree, found in South Americs is the natural rubber which was used up until 1839. This was the year that Charles Goodyear accidentally discovered vulcanization of rubber for industrial uses.

Natural latex is made from 100% natural rubber. Talalay latex is a type of latex that combines natural and synthetic latex usually 70% natural latex and 30% synthetic rubber made from raw materials derived from oil based products.

The paper and the tobacco will begin to break down as soon as it gets wet; BUT if the butt contains a plastic filter it may take a thousand years.
Natural rubber is easily attacked by many oils, and solvents. In the open, ozone also attacks the intermolecular bonds.
No. Vulcanized rubber (usually artificial rubber) is very difficult to reprocess. This is why there are many millions of trashed tires accumulating in areas of the US and elsewhere. Sometimes they are burned, or shredded to use in various products. Or they may be used to form artificial reefs. But this occurs for only a small fraction of used tires. Most are left to slowly biodegrade over hundreds of years.
