vulcanize
/ˈvʌlkənʌɪz
/(also vulcanise)
verb [with object]
Harden (rubber or rubber-like material) by treating it with sulphur at a high temperature: (as adjective vulcanized) the development of a method for fixing vulcanized rubber firmly on to mild steel...
- Some of the first useful polymers were chemically modified natural polymers such as vulcanized rubber and cellulose acetate.
- This rubber can be vulcanized (treated under heat and pressure with sulfur to improve elasticity and strength).
- For example, I can recall from elementary school the story of Charles Goodyear and vulcanizing rubber.
Derivatives
vulcanizable
- This material is again vulcanisable and does not require any auxiliary agents for this process.
- In contrast to chemical cross-linking in the case of vulcanisable rubbers, this process is reversible.
- The sealing mixture obtained after mixing is vulcanisable at room temperature and can be processed during one day.
vulcanization
- It is used in the manufacture of antioxidants, pharmaceuticals, dyes, and in the vulcanization of rubber.
- Natural rubbers, before vulcanization, tend to be sticky and soft at high temperatures, while at low temperatures they are brittle and stiff, making them difficult to process.
- Aniline is used in the manufacture of a number of products including dyes, pharmaceuticals, antioxidants, and vulcanization accelerators in rubber compounds.
vulcanizer
- The rubber is cut to the size of the mold, placed in the vulcanizer, and creates a rubber stamp through a similar process of heat and pressure.
- Use an accurate glass or metal thermometer and make sure that your vulcanizer is really performing as expected before attempting to use this rubber.
- When portability is essential, the SVP conveyor belt vulcanizer meets the needs of a variety of job requirements.
Origin
Early 19th century (in the sense 'throw into a fire'): from Vulcan + -ize.
