It's a process called "vulcanization."
sulfur
Vulcanized rubber is process that changes the properties of natural rubber so that it is more usable for products. Natural rubber hardens rock-solid in freezing temperature and melts into goo in summer heat. For an interesting reprint of a Readers Digest article on the invention of rubber - see the attach link.
mixture of water-cement-fine sand in a certain ratio which is usable to fill gaps, voids and other repairing purpose
usable water
Both usable.
Usable, with no restrictions.
rubber is the sap from a tree. cook it down to a syrup then add sulfur to crosslink the polymer chains and you have usable vulcanized rubber.
Natural Rubber is like chewing gum.To make a stable usable product you mix in sulphur and heat the mixture up. This is called Vulcanization.This is how tires, Bouncy balls, etc were made until the second world war.Since then the process is similar but the ingredients have change to give us synthetic rubber.
If you mean a mixture of metallic elements, it is an alloy.

Yes, usable is an adjective to describe a noun as able to be used; for example usable information.
Usable is an adjective used to describe something/someone.
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.
"Usable" is spelled as U-S-A-B-L-E.
