What Is Vulcanized Rubber? – Properties, Applications, Uses

What Is Vulcanized Rubber

What Is Vulcanized Rubber –Vulcanization is the process of heating liquid rubber with sulphur to cross-link rubber molecules, polymers, or macromolecules made up of repeated units or monomers called isoprene.

What Is Vulcanized Rubber

 

Rubber’s elasticity and strength are improved tenfold by cross-linking, but the amount of cross-linking must be carefully regulated to avoid brittle and inelastic effects. When inventor Charles Goodyear dropped some sulfur-containing rubber onto a hot stove, he discovered the vulcanization mechanism by mistake. Goodyear pursued this discovery and established the method.

THE IMPACT OF VULCANIZATION ON RUBBER?

Vulcanization causes the rubber to retract, altering its physical properties. Mechanical techniques can also be used to compel rubber to withdraw.

The difference between vulcanization and other techniques is that vulcanization keeps the rubber in its original form.

As rubber is vulcanised, the rubber shrinks while preserving its original form. Vulcanization is the process of shrinking rubber to a smaller size without deforming or changing its shape.

Vulcanization not only changes the size of rubber while preserving its shape but it also prevents it from potential deformation. Rubber hardens and becomes less susceptible to deformation as it shrinks.

When exposed to enough stress, vulcanized rubber will deform but it will not deform as easily as non-vulcanized rubber. As rubber is vulcanized, it becomes stronger, increasing its tensile strength and lowering the risk of physical damage.

APPLICATIONS OF VULCANIZED RUBBER?

Today, vulcanised rubber is used to produce a wide variety of goods. Vehicle tyres are probably the most well known and widely used application of vulcanised rubber, which are often reinforced with carbon black for added protection.

Every year, more than a billion tyres are produced around the world, making the tyre industry one of the largest users of vulcanised rubber. Other common applications for vulcanised rubber include: Belt Conveyors, erasers, toys, shoe soles and hoses, etc

PROPERTIES OF VULCANISED RUBBER

Vulcanized Rubber is resistant to alkalis and weak acids and repels water. Vulcanized Rubber is useful as an adhesive, a coating composition, a fibre and an electrical insulator due to its elasticity, resilience, impermeability, adhesiveness and electrical resistance.

In general, vulcanized rubber outperforms in terms of ageing and weathering, resistance to oil, solvents, oxygen, ozone, and some contaminants and temperature stability across a wider range.

Vulcanized rubber has the advantages of less heat buildup from flexing and greater resistance to tearing when humid.

ADVANTAGES AND DISADVANTAGES OF VULCANIZED RUBBER

ADVANTAGES

Rubber shrinks while maintaining its original form when it is vulcanised. The vulcanization process also hardens the rubber, making it less prone to deformation particularly when compared to non vulcanized rubber, which deforms much more easily when stressed.

The rubber’s tensile strength is also improved as it hardens. Since its bonds are made of cross links at the atomic level, vulcanised rubber is stronger. Vulcanized rubber can withstand more stress and damage as a result of this.

Vulcanized rubber is also stiffer than non-vulcanized rubber, making it more stretch resistant, to begin with. Vulcanized rubber, on the other hand, has the same elasticity as non vulcanized rubber

DISADVANTAGES

Vulcanized rubber does not have many disadvantages, but it does have a few drawbacks.

Rubber is slightly poisonous when burned and cools easily after melting, posing a risk to those who handle it. In most situations, the only way rubber will hurt anyone is if he or she deliberately burns it.

CONCLUSION

We hope you can use this knowledge to source efficiently for your needs, now that we have covered the basics of Vulcanized rubber, such as what it is, its properties and its applications.

However, Vulcanized rubber is only one of the several common types of rubbers, each with its own set of characteristics and applications.
