The first process, called Pressure Vulcanization involves heating the rubber with sulfur under pressure, with a temperature of 150C. The second process, called Free Vulcanization, simply involves passing very hot steam or air through the rubber.
How do you make vulcanized rubber?
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.
What is the difference between rubber and vulcanized rubber?
Natural rubber is a naturally occurring material while vulcanized rubber is the material that forms after the vulcanization of natural rubber. The key difference between natural rubber and vulcanized rubber is that natural rubber is thermoplastic whereas vulcanized rubber is a thermoset.
