What is vulcanization of rubber?

Vulcanization is a chemical treatment that heats rubber with sulfur or other curing agents to create cross-links between polymer chains. This process transforms the rubber from a soft, pliable state into a durable, elastic material with enhanced strength, heat resistance, and longevity.

How do plasticisers & vulcanising agents make rubber more elastic?

Plasticisers: Plasticisers soften rubber and make it easier to mould. They keep rubber elastic at low temperatures, helping it to remain flexible and easy to process. Vulcanising agents: Vulcanising agents, such as sulphur, are ‘reinforcing agents’ for rubber. They make rubber stronger and more elastic by cross-linking its molecular structure.

When was rubber vulcanized?

The vulcanization of rubber began with Charles Goodyear’s groundbreaking discovery in 1839. Here’s how it evolved. 1839: Goodyear accidentally mixed sulfur with raw rubber and exposed it to heat, revolutionizing rubber’s properties. Early Applications: Waterproof shoes and durable industrial components.

What is vulcanization used for?

Modern Techniques: Advanced curing agents and methods, such as microwave vulcanization and silicone rubber vulcanization, have refined the process for higher efficiency and versatility. Today, vulcanization is used to produce everything from custom rubber gaskets to rubber tubing for medical and industrial applications.

What is the difference between vulcanized rubber and rubber cement?

Rubber cement is a temporary adhesive used for bonding, while vulcanized rubber is a chemically treated material that is durable, flexible, and resistant to heat. Why is vulcanized rubber better than raw rubber?

What is a rubber compound?

A rubber compound is like a formula that gives rubber its unique properties. It is made by mixing raw materials such as natural rubber, fillers and additives. The process is similar to cooking – choosing the right ‘ingredients’ according to the desired qualities.
