Vulcanisation is used in processing of:a)Rubberb)Polythenec)Bakelited)...
The correct answer is option A
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.

Process of Vulcanisation:
The process of vulcanisation involves the following steps:
- Mixing natural rubber with sulfur and other additives such as accelerators and activators.
- Molding the mixture into the desired shape.
- Heating the rubber at high temperatures (140-180°C) for several hours.
- Cooling the rubber to room temperature.
Advantages of Vulcanisation:
Vulcanisation offers several advantages over untreated rubber, including:
- Improved strength and durability.
- Increased elasticity and flexibility.
- Resistance to high temperatures and chemicals.
- Resistance to aging and oxidation.
Applications of Vulcanised Rubber:
Vulcanised rubber is used in a variety of applications, including:
- Tires for automobiles, bicycles, and motorcycles.
- Industrial hoses and belts.
- Gaskets and seals.
- Electrical insulation.
- Sporting goods such as balls and shoes.
Conclusion:
In conclusion, Vulcanisation is a chemical process that is used to enhance the properties of natural rubber. It involves heating rubber with sulfur to improve its strength, elasticity, and durability. Vulcanised rubber has several advantages over untreated rubber and is used in a variety of applications.
