2. What is Plastic Sulphur ? A form of rubber-like Sulphur - produced when molten Sulphur is rapidly poured into cold water. (It is only produced with red molten Sulphur that contains S8 chains.) The S8chain Sulphur cools too rapidly to allow the chains to reform into crowns and they lose energy while parallel to one another. This creates a structure with the chains all aligned but only held by the Van der Waals’ forces. Plastic sulphur is unstable at room temperature, as the S8 chains slowly return to S8 crown molecules. The rubber-like structure gets more brittle as the crystals are slowly formed.
