Dpg (d) Elemental Sulfur For Natural synthetic Rubber in United Kingdom
Sulfur vulcanization
Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Even with natural rubber, large amounts of sulfur as well as high temperatures and long heating periods are necessary, with the end products often being of an unsatisfactory quality.

Rubber - Additives | Britannica
Rubber - Rubber - Additives: A number of ingredients are added to both natural and synthetic rubber in order to obtain certain desirable properties. By convention, mix formulations begin with the amount of the designated elastomer—for instance, natural rubber (NR), butadiene rubber (BR), or styrene-butadiene rubber (SBR)—given as 100 parts by weight.

An Effective Solution for Elemental Sulfur Deposition
Zealand, Norway, Russia, Saudi Arabia, the United Kingdom, and USA. Solid elemental sulfur has a vapor pressure, even at ambient and sub-ambient temperatures. Under the right conditions sublimation will occur from the vapor phase to the solid phase causing the sulfur to deposit in various areas of the natural gas system.
