Charles Goodyear and the Vulcanization of Rubber
At that time, rubber appeared to be a “miracle material.” The gooey, milky sap, bled from trees in Brazil, was waterproof and easy to stretch. Called latex in its fluid form and rubber when it hardened, the substance could be formed to fit a variety of uses. Rubber barons and wealthy families staked their fortunes on its potential.

Vulcanization - an overview | ScienceDirect Topics
Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.

FAQ - Rubber Lined Tank Experts | Abtrex Industries
Rubber is comprised of long polymer chains. These chains can move independently of each other, distorting the material. Vulcanization crosslinks the chains and prevents this movement. Basically, vulcanized rubber has a memory; it will distort under stress, but will return to shape after the stress is removed. Other benefits are:

What is Vulcanized Rubber? (with pictures)
Vulcanized rubber is a natural elastomer that has been made more durable by a biochemical process that cures the rubber. During vulcanization, the milky latex from a rubber tree is combined with a curing ingredient — usually sulfur — and heated under pressure.

Is Rubber Eco Friendly?
Vulcanization involves the adding of sulfur to the rubber itself, in order to create “cross-linked” bonds that strengthen the material. De-vulcanization, then, involves the destruction of these bonds to bring the rubber back to a more pliable state.

How does rubber vulcanization work? - Answers.com
Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Even with natural rubber, large amounts of sulfur, as well as high temperatures and long heatingOnly with vulcanization accelerators can the quality corresponding to today's level of technology be achieved.

What is vulcanised rubber? | 10 Answers
How Vulcanized Rubber is Made. It is necessary to use vulcanization to make commercial-grade rubber because natural rubber is not stable enough to produce goods with.Vulcanized rubber is stronger than non-vulcanized rubber because its bonds are made of cross-links at an atomic level.
Send InquiryWhat is the chemical equation for the vulcanization of rubber?
Best Answer: Vulcanized rubber is a non-molecular solid, as such, it does not have a molecular formula like water. It is a polymer of isoprene [ poly(isoprene) ], doped or 'vulcanized' with sulfur to make the rubber more durable amongst other things.

Vulcanization of rubber [SubsTech]
Vulcanization of rubber is a process of improvement of the rubber elasticity and strength by heating it in the presence of sulfur, which results in three-dimensional cross-linking of the chain rubber molecules (polyisoprene) bonded to each other by sulfur atoms.
