    Thiokol is a trade mark for various organic polysulfide polymers. [1] Thiokol polymers are used as an elastomer in seals and sealants.The distinction between the polymers first commercialized by the Thiokol Chemical Company and subsequent polysulfide materials is often unclear.

  5. Sodium polysulfide - Wikipedia

    en.wikipedia.org/wiki/Sodium_polysulfide

    Sodium polysulfide is a general term for salts with the formula Na 2 S x, where x = 2 to 5. The species S x 2−, called polysulfide anions, include disulfide (S 2 2−), trisulfide (S 3 2−), tetrasulfide (S 4 2−), and pentasulfide (S 5 2−). In principle, but not in practice, the chain lengths could be longer.

  7. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...
