The chemical industry is an industry involved in the production of chemicals. This industry includes the production of petrochemicals, agrochemicals, pharmaceuticals, polymers, paints, and oleo chemicals. The chemical industry as a whole is involved in chemical processes which include chemical reactions to form new substances, separations based on properties such as solubility or ionic charge, and distillations, besides transformations by heating and other methods. It is involved in the processing of raw materials obtained by mining, agriculture among other supply sources, into materials, substances, chemical compounds that are finished products or are used in other industries.
Rubber Products in chemical industry
There are wide varieties of rubber products manufactured for a full range of Chemical Metering and Dispensing Equipment Applications. Besides the rubber products, rubber is itself used in various chemical processes. In practically all chemical plants, there are some process or reaction in which a corrosive reagent is used or produced. Hard rubber of suitable compound is chemically inert to a high degree and is used in connection with a great many corrosive materials. Essentially, hard rubber is rubber compounded with a relatively high percentage of sulfur. Many laboratory tests have been made in which hard rubber has been mixed in various chemicals for long periods of time. Various chemical acids like sulfuric acid , nitric acid, hydrochloric acid, acetic, hydrofluoric, phosphoric acids, sodium and potassium salts, zinc chloride, calcium chloride, and many others, as well as corrosive gases, such as chlorine, hydrochloric acid gas, etc. use hard rubber in their chemical processing. Hard rubber is also attacked by most rubber solvents, such as benzene, carbon disulfide, and chloroform, which soften and swell the rubber.
