Rubber made by vulcanization is ___________material.

Hint: In common terms vulcanization of rubber means applying some range of processes to make it hard. Thus with the help of vulcanization the quality of rubber can be improved. It will become harder which makes it suitable for industrial and commercial use. Now the rubber will become better than previous for its use.

Complete Step By Step Answer:
Vulcanization of rubber is a chemical process through which the physical and chemical properties of a natural substance can be changed for better use in future. With the help of vulcanization the tensile strength of rubber can be enhanced. It will become more elastic than previous by the help of vulcanization. Basically this process of vulcanization takes place by heating the natural rubber in the presence of sulfur. Thus we get the cross linked structure of rubber which makes it more useful in industries and also commercially. To proceed this process of vulcanization faster we add some material known as accelerator which helps in more production of the vulcanized rubber. Therefore we can say that rubber made by vulcanization is a man-made material. Since its quality also improves, we can say that rubber made by vulcanization is a better material. But overall the properties of the natural are completely changed in the process of vulcanization which is the advantage of the process.

Note:
Nowadays sulfur is not added with natural rubber during the process of vulcanization due to some environmental issues. Thus some metal oxides or even peroxides are added to natural rubber for vulcanization which give us a similar quality of vulcanization as produced by adding sulphur.
