Carbon Disulfide
Carbon Disulfide (CS₂) is a volatile, flammable, and highly toxic organic solvent composed of carbon and sulfur. At 99% purity, it is a clear to pale yellow liquid with a pungent, sweet, ether-like odor. Carbon Disulfide is produced primarily by the reaction of carbon (charcoal) with sulfur vapors at high temperatures. Due to its excellent solvent properties and reactivity, it is used across multiple industries, including the production of rayon, cellophane, rubber chemicals, and pesticides. Despite its utility, Carbon Disulfide requires careful handling because of its toxicity, flammability, and environmental hazards.
Ink reducer (Ethanol)
Ink reducer (Ethanol) is a volatile, colorless liquid used to adjust the viscosity, flow, and drying time of printing inks. Composed primarily of high-purity ethanol (ethyl alcohol), it acts as a solvent or diluent in various ink systems—particularly in flexographic, gravure, and screen printing. This reducer enhances printability by improving ink transfer, leveling, and penetration into substrates. Ink reducers based on ethanol are fast-drying and widely compatible with alcohol-soluble and water-alcohol hybrid inks used in packaging, label printing, and paper conversion industries.
