Paraformaldehyde (PF) 91%

Paraformaldehyde (PF) 91%

Category:

Industrial Chemical / Polymerized Formaldehyde / Chemical Intermediate

Description:

Paraformaldehyde (PF) 91% is a white, free-flowing polymerized form of formaldehyde containing approximately 91% formaldehyde by weight. It is a highly concentrated solid source of formaldehyde, commonly used in resins, agrochemicals, pharmaceuticals, disinfectants, and industrial chemical synthesis. Known for efficient reactivity, PF 91% acts as a convenient alternative to aqueous formaldehyde solutions, especially where low moisture content and higher purity are required.

Applications:

• Manufacture of amino resins (UF, MF resins)
• Agrochemical intermediate (herbicides, pesticides, fungicides)
• Disinfectants and biocide formulations
• Pharmaceutical intermediates
• Rubber and plastics chemical synthesis
• Lubricant and fuel additive manufacturing
• Paper, leather, and textile processing chemicals
• Laboratory fixatives and preservatives

Storage & Handling:

• Store in cool, dry, well-ventilated area
• Keep containers tightly closed to minimize formaldehyde vapor release
• Avoid heat, moisture, and incompatible materials
• Wear gloves, goggles, and protective clothing during handling
• Ensure proper ventilation or exhaust systems
• Avoid inhalation and contact with skin or eyes
