Question

what is vulcanization​

Answer 1

Answer:

Vulcanization is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other rubbers via various means.

Answer 2

• Vulcanization is a chemical process that improves the physical qualities of natural or synthetic rubber.
• The final rubber has a higher tensile strength, is less prone to swelling and abrasion, and is more elastic across a wider temperature range.
• Vulcanization is accomplished by heating rubber with sulphur in its most basic form.
• Charles Goodyear, a U.S. inventor, discovered the method in 1839 and identified the critical role of several other compounds in the process.
• Vulcanization proceeds more quickly or at lower temperatures when a substance known as an accelerator is used.
• Sulfur is not simply dissolved or scattered in the rubber; it is chemically bonded, primarily in the form of cross-links, or bridges, between the long-chain molecules.
