Definition
- Noun:
- A chemical process: Vulcanization is the industrial process of treating natural rubber or similar polymers with sulfur or other curatives, typically under heat and pressure. This process forms cross-links between polymer chains, which permanently alters the material's properties, making it more durable, elastic, and resistant to wear and temperature changes.
Usage Examples
- Noun:
- The invention of vulcanization by Charles Goodyear revolutionized the rubber industry.
- The durability of these tires is due to a precise vulcanization process.
- Without vulcanization, rubber products would become sticky in heat and brittle in cold.
Advanced Usage
- Technical Context: In materials science, "vulcanization" specifically refers to the cross-linking of elastomer molecules. The degree of vulcanization affects the final product's hardness and elasticity.
- The engineer adjusted the vulcanization parameters to achieve the desired shore hardness for the gasket.
Variants and Related Words
- Vulcanize (verb): To subject a material to the vulcanization process.
- The rubber must be vulcanized to be used in automotive belts.
- Vulcanized (adjective): Describing a material that has undergone vulcanization.
- He wore shoes with vulcanized rubber soles.
- Vulcanizer (noun): A person who carries out vulcanization or a machine used for the process.
Synonyms
- Curing: A broader term often used interchangeably in the context of rubber and polymer hardening.
- Cross-linking: The specific chemical action that occurs during vulcanization.
Related Phrases/Compounds
- Vulcanization accelerator: A chemical additive used to speed up the vulcanization process.
- Post-vulcanization: Any treatment or property change that occurs after the main vulcanization process is complete.
Noun
- process of treating rubber or rubberlike materials with sulphur at great heat to improve elasticity and strength or to harden them
