Rubber is an elastic hydrocarbon polymer which occurs as a milky colloidal suspension (known as latex) in the sap of several varieties of plants. Rubber can also be produced synthetically.
Explanation
Synthetic rubber is made through the polymerization of a variety of monomers to produce polymers. These form part of a broad study covered by polymer science and rubber technology. Its scientific name is polyisoprene.
Sources
The major commercial source of natural latex used to create rubber is the Para rubber tree, Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Henry Wickham gathered thousands of seeds from Brazil in 1876 and they were germinated in Kew Gardens, England. The seedlings were sent to Colombo, Indonesia, Singapore and British Malaya. Malaya was later to become the biggest producer of rubber.
Other plants containing latex include figs (Ficus elastica), euphorbias, and the common dandelion. Although these have not been major sources of rubber, Germany attempted to use such sources during World War II when it was cut off from rubber supplies. These attempts were later supplanted by the development of synthetic rubber. Its density is 920 kg/m3.

Natural rubber is a white liquid (latex) extracted from the rubber trees. Highly used to make vehicle tires. Synthetic rubber are made out of polymerization of chemicals. Some examples of synthetic rubber are neoprene, silicone, butyl and so on. Rubber undergoes vulcanization process in order to manufacture different kinds of industrial and home purpose rubber products.

Natural latex is made from the rubber tree (Euphorbiaceae.)
The trees are slashed in a criscross pattern so the sap (milky white stuff) flows and collects in blobs. This stuff is then heated up and used to make stuff like condoms and rubber gloves.
The stuff in tires has sulfur mixed in it (vulcanization.)

well rubber comes from the rubber trees in the rainforests of south america i believe
at least thats where the rubber for tires came from when henry ford went to south america looking around for new ideas on cars and thats stuff

nowadays it is made from the byproducts of polymers being made into plastics but a long time ago it was made from the sap of a rubber tree
