Description

Paraformaldehyde is a high-purity polymeric form of formaldehyde, widely recognized as a critical reagent and chemical intermediate in industrial synthesis. Its controlled release of formaldehyde upon heating makes it a versatile and safer-to-handle alternative to gaseous formaldehyde solutions. This product is essential for manufacturers in the agrochemical, resin, and pharmaceutical sectors, where it serves as a key building block for synthesizing various active ingredients, adhesives, and disinfectants.

Application

• Chemical Synthesis: A fundamental reagent for producing herbicides, pesticides, and other agrochemicals.
• Resin Manufacturing: A crucial cross-linking agent in the production of phenolic resins, urea-formaldehyde resins, and other thermosetting polymers used in adhesives, coatings, and molded products.
• Disinfectant & Biocide Formulation: Used as a source of formaldehyde in disinfectants, fumigants, and preservatives for industrial and agricultural applications.
• Pharmaceutical Intermediates: Employed in the synthesis of various active pharmaceutical ingredients (APIs) and other fine chemicals.
• Laboratory Reagent: Utilized in research and development as a fixative and a source of anhydrous formaldehyde for organic reactions.
• Textile Treatment: Acts as a cross-linking agent in durable press finishes for fabrics to improve wrinkle resistance.

Quality Control

Our Paraformaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, including testing for formaldehyde content, ash, and acidity. A Certificate of Analysis (COA) detailing all specifications and test results is supplied with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept sealed when not in use to prevent sublimation and maintain product integrity. Recommended storage temperature is 15-25°C.
