This product, sometimes referred to as rubber makers is very fine and very pure. The minimum purity from this manufacturer is 99.5% but the certificate of analysis shows it at 99.95%. It is recovered during gas manufacturing as a molten sulfur. It is then cooled on a stainless steel belt and forms into a flake form. The flakes are then taken off the belt and ground into a fine powder.
Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth.
Sulfur can increase the sensitivity of some mixtures, especially those based on chlorate or perchlorate oxidizers. Mixtures of chlorates and this are also known to ignite spontaneously and should therefore be avoided at all times. Mixtures of perchlorates and this are less likely to ignite spontaneously but are still very sensitive and need to be treated with extreme caution.
Burning will produce sulfur dioxide gas, inhalation of which should be avoided because it is extremely poisonous.
