They collect latex from the rubber tree by tapping it and let it drip into a bucket and wait till it stops. It is then processed and various chemicals added, predominately sulphur to allow it to be hard and still flexible at the same time.
Well, there are rubber trees, but you have to turn the rubber in the tree into rubber bands
The rubber that comes from oil is called 'synthetic rubber'. The rubber that comes from trees is called 'natural rubber'.
Rubber is primarily made from natural latex, which is obtained from the sap of rubber trees, particularly the Hevea brasiliensis species. This latex is harvested by tapping the trees, a process that involves making incisions in the bark. Additionally, some synthetic rubber is produced from petroleum-based chemicals, but natural rubber remains a significant resource derived from these trees.
There is natural rubber, made from the latex of the rubber tree (Hevea brasiliensis).There are several manmade rubber compounds, including butyl rubber, neoprene, and nitrile rubber.
Resin or Natural Rubber can be made from the sap of trees.
A major source of commercial natural rubber latex is from the Pará rubber tree (Hecea brasiliensis). There are also other species of rubber producing trees.
Both maple syrup and natural rubber are made from the sap of trees
Some erasers have rubber(natural or synthetic). The rubber is made from rubber trees. It also contains styrene, buadience, sulpher, vynil, colorants( to get it the color you want like green for example), pumice, and vegetable oil.
Natural rubber is typically a milky white colour when it is harvested from rubber trees. However, it can also have a yellow tint due to oxidation over time.
Synthetic rubber is made from molecules generated during the process of refining crude oil or natural gas liquids. Natural rubber is derived from rubber trees and is not derived from oil.
Most rubber comes from the sap of hevea trees. The trees originated in Brazil, but are now also grown in Southeast Asia.
Before the invention of "Synthetic Rubber", natural rubber grew inside of trees (called rubber trees). Vietnam was rich in rubber trees. During the Vietnam War, US armored columnes frequently engaged NVA troops inside the rubber tree plantations.
