| 21. | Additionally, solid silicone rubber materials are processed at higher temperatures and require longer vulcanization times.
|
| 22. | For example, the vulcanization of polyisoprene results when mercapto radicals couple forming disulfide and polysulfide crosslinks.
|
| 23. | Hutchison had obtained a license in 1850 from fellow American Charles Goodyear's patented vulcanization process.
|
| 24. | "' Sodium lignosulfonate "'( lignosulfonic acid, rubber vulcanization, organic polymerization.
|
| 25. | It is also useful as a catalyst for transesterification and for the room temperature vulcanization of silicones.
|
| 26. | Driven by software, a series of robots carry the tires right through construction to molding and vulcanization.
|
| 27. | Elastomers are usually thermosets ( requiring vulcanization ) but may also be thermoplastic ( see thermoplastic elastomer ).
|
| 28. | In the rubber and plastics industries, it is an antioxidant, vulcanization accelerator, and radical scavenger.
|
| 29. | Western inventors discovered the properties of gutta-percha latex in 1842, although the people of its vulcanization.
|
| 30. | As mentioned previously, vulcanization is a necessary step to prepare the uncured silicone mold for spin casting production.
