Natural rubber is produced from plants and is classified as a polymer. A polymer is a chemical compound with large molecules made of many smaller molecules of the same kind......
Some polymers exist naturally and others are produced in laboratories and factories.
Natural
rubber is one of the most important polymers for human society. Natural
rubber is an essential raw material used in the creation of more than
40,000 products. It is used in medical devices, surgical gloves,
aircraft and car tires, pacifiers, clothes, toys, etc. Natural rubber is
obtained from latex, a milky liquid present in either the latex vessels
(ducts) or in the cells of rubber-producing plants.
Around
20,000 species of plants produce latex, but only 2,500 species have
been found to contain rubber in their latex. The biological function of
rubber for the plants is not fully known. However, it has been shown
that rubber can help plants to heal after they are damaged, by covering
wounds and stopping the bleeding. This blocks the entry of harmful
bacteria and viruses into the plants.
The properties of rubber
include high strength and the capability to be stretched many times
without breaking. Natural rubber compounds are exceptionally flexible,
good electrical insulators, and are resistant to many corrosive
substances.
Synthetic (man-made) rubber can be produced through a
chemical process, but people have not been able to produce a synthetic
rubber that has all the properties of natural rubber. So, natural rubber
cannot be replaced by synthetic rubber in most of its applications.
This is why natural rubber is still very important to human society
getting information like this is one major reason you need to attend
World Rubber and Plastic Expo.
