7. Question & Answer

What gives natural rubber a permanent shiny finishing? Apr 19 2022
Natural rubber is made by vulcanizing latex mixed with sulphur. Commonly, the resulting natural rubber is dull instead of shiny. However, there are also products made out of natural rubber that are shiny, such as the wellington boots in the picture below. My question is: In addition to vulcanizatio...
