Sulphur Dispersions

Powdered sulphur use covers a broad range of applications. Sulphur appears light yellow in color and is found naturally in hot springs, meteorites, volcanoes and salts. Both the powder size and the dispersing medium depends on its intended use.

Sulphur in Agriculture

The farming and gardening industry relies heavily on sulphur in powdered form as it is a primary element needed for plant growth. Sulphur can be applied to adjust the pH balance of soil to optimize the growing conditions. Powdered sulphur is a popular pesticide and fungicide to control unwanted fungus growth or pests on fruits, flowers and vegetables. It also acts as a preservative for a variety of fruits and vegetables, extending the shelf life of freshness.

Sulphur in Rubber Industry

Powdered sulphur also plays an important role in the rubber industry. Some rubbers rely on sulphur dispersion to create their unique properties. A lack of homogeneity in the product can result in a spotty appearance in the rubber product.

Sulphur Nanoparticle Dispersions

Very fine sulphur powders can be used to increase particle dispersion and, in-turn, product efficacy. These are called sulphur nanoparticles. They are dissolved in water or other organic solvents such as ethanol or mineral oil to create sulphur nanoparticle dispersions.

Sulphur dispersion requires solid knowledge of the material and applications. Depending upon the intended use and the dispersion medium, the particle size will vary. However, it’s important that regardless of particle size, all particles are evenly ground. Sulphur dissolves quickly, making the size and consistency of the powder important for even distribution.
