Paraformaldehyde
Paraformaldehyde (PFA)
Polyformaldehyde is the solid form of liquid formaldehyde, formed by the polymerization of formaldehyde, with a typical polymerization degree of 8-100. Due to its nature as a condensed form of formaldehyde, polyformaldehyde has a wide range of applications, stable purity, and reliable quality, making it the preferred choice for manufacturers pursuing efficient production and high-performance chemical formulations.

Applications of Paraformaldehyde
Paraformaldehyde has a wide range of applications, mainly in chemical industry, pesticides, resins, pharmaceuticals and disinfection. The largest consumption field is herbicide production, especially glyphosate.
🌾 Pesticide Industry
- Herbicides: Paraformaldehyde is a key raw material for glyphosate and is also used to synthesize acetochlor, butachlor, and other herbicides.
- Other pesticides: Used to produce insecticides and fungicides.
🧪 Resin & Chemical Synthesis
- Synthetic Resins: Used to manufacture urea-formaldehyde resin, phenolic resin, melamine resin, ion exchange resin, etc.
- Organic Synthesis: Serves as a formaldehyde source for the Prins reaction and various hydroxymethylation reactions, producing ethylene glycol, trimethylolpropane, and N-methylolacrylamide.
- Adhesives: Raw material for adhesive manufacturing.
