Formaldehyde

Formaldehyde (CAS 50-00-0), also known commercially as Paraform in its solid polymerized form and listed as E240 in food-related contexts, is a high-demand chemical intermediate. It is a biocidal agent used across industrial manufacturing and preservation applications. It functions primarily as a crosslinking agent, disinfectant, and reactive monomer in the production of resins and polymers.

In chemical manufacturing, it is the foundational building block for urea-formaldehyde and phenol-formaldehyde resins used in adhesives, laminates, and molded components for various industrial sectors. Textile and leather processors apply it as a crosslinking agent to impart wrinkle resistance, dimensional stability, and wet strength to finished goods during the manufacturing process.

Water treatment operations use it as a biocide to control microbial growth in industrial cooling systems and process water. In personal care, it functions as a preservative in low-concentration formulations. Pharmaceutical producers rely on it for equipment sterilization and vaccine inactivation processes. Formaldehyde is supplied as an aqueous solution, most commonly at 37% concentration known as formalin.

It is also available in solid polymerized form as paraformaldehyde powder or prills. Technical and industrial grades are standard for resin and chemical synthesis applications across the global market. Pharmaceutical and reagent grades are available for controlled manufacturing environments requiring tighter purity specifications. These grades ensure compliance with rigorous safety and quality protocols.
