How Rubber Is Made/ Fun Facts

These scraps then adhered into solid rubber that could be shaped, pressed into various molds, or made into long sheet of rubber. This masticator made manufacturing rubber pliable which opened the doors to the rubber industry. Vulcanization During the 1830's manufacturing rubber became a serious problem. In the winter time became rigid and hard.

Vulcanization Facts for Kids

Vulcanization is a kind of chemical reaction between sulphur, or another agent, and natural rubber.It makes cross-links between the molecular chains in the rubber. The reaction is not reversible. The purpose of this is to harden the rubber so it does not melt or soften in relatively low temperatures.

How to Remove Vulcanized Rubber From Metal

Vulcanized rubber is more durable and elastic than natural rubber, giving it a wider range of commercial applications. Vulcanized rubber is attached to metal in a variety of products, usually with contact cement or another adhesive. To remove vulcanized rubber from metal you must strip away the rubber then remove the adhesive layer between the

Sulfur vulcanization

Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties.

Sulfur Vulcanization

Vulcanization is a chemical process that converts natural rubber and other polydiene elastomers into cross-linked polymers. The most common vulcanization agent is sulfur. It forms bridges between individual polymer molecules when heated with rubber. Often a catalyst and initiator is added to accelerate the vulcanization process.

History of the Vulcanization of Rubber

Not unlike curing, vulcanization is the treatment of rubber with heat and originally sulfur to bring it to a molecular state which can be used in a variety of applications. Adding sulfur to the vulcanization process gives the rubber better strength, elasticity, and durability. Natural rubber is most like chewing gum or Play-doh in its natural state.

Making Rubber Stronger: How to Vulcanize Rubber

Making Rubber Stronger Through Vulcanization Rubber is a polymer of isoprene that is formed with double bonds between each of the individual monomers (or units). In simple terms, one of these bonds is flexible and can allow the polymer to take up many shapes and sizes, which is what basically gives rubber its property of elasticity.

Vulcanized Rubber Molds

In the mid 1800's, Charles Goodyear discovered that by adding sulfur, heat and pressure to the rubber, a process called vulcanization occurs. The sulfur bonds to the rubber molecules and "cross-links" them. In effect it bridges the gaps between the rubber molecules and pulls them into a cohesive "super molecule".

Rubber Chemistry

In rubber, the monomer is a carbon compound called isoprene that has two carbon-carbon double bonds. The latex fluid that seeps from rubber trees has many isoprene molecules. As the latex dries, the isoprene molecules crowd together and one isoprene molecule attacks a carbon-carbon double bond of a neighboring molecule.
