White powdery solid with a pungent odor (formaldehyde-like smell). A flammable solid, linear polymer of formaldehyde, no fixed melting point. Decomposes upon heating, releasing toxic formaldehyde gas. Melting range: 120–170°C, flash point: 70°C, ignition temperature: 300°C, explosive limits: 7.0–73.0%. Soluble in water (releasing formaldehyde), slowly dissolves in cold water, soluble in sodium hydroxide and carbonate solutions, insoluble in alcohols and ethers.

Applications:

Paraformaldehyde replaces industrial formaldehyde solutions in synthesizing pesticides, resins, coatings, and fumigation disinfectants. It reduces dehydration energy consumption and wastewater treatment demands, serving as an eco-friendly raw material. Its high formaldehyde content and solid form make it ideal for chemical synthesis (e.g., pharmaceuticals, organic chemicals) requiring anhydrous formaldehyde. Also used as a disinfectant, sterilizer, fumigant, herbicide, resin, and artificial ivory.
