Dye intermediates are petroleum downstream products, which are further processed for any application. On processing they are transformed to finished dyes and pigments. The dye intermediates serve many industries like textiles, plastics, paints, printing inks and paper.
Speciality chemicals are materials used on the basis of their performance or function. Consequently, in addition to "effect" chemicals they are sometimes referred to as "performance" chemicals or "formulation" chemicals. They can be unique molecules or mixtures of molecules known as formulations.
Dyes are the chemical substances that impart their colour to an article and are soluble in water. Dyes can be natural or synthetic Natural dyes: When the dye is obtained from the plants, it is called as a natural dye. Examples: Dyes obtained from beetroot, flowers etc. Synthetic dyes: When the dye is man-made using certain chemicals called coloured pigments, it is called as a synthetic dye. Example: Alizarin red, Indigo blue.
Petrochemicals are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane. The two most common petrochemical classes are olefins (including ethylene and propylene) and aromatics (including benzene, toluene and xylene isomers).
