Paraformaldehyde is a linear oligomer of formaldehyde. It appears as a white amorphous powder or granule with a characteristic pungent odor of formaldehyde. It is a flammable solid with strong hygroscopicity.It is stable at room temperature, but will rapidly depolymerize and release formaldehyde gas when heated or in contact with acids and alkalis. The polymerization degree of industrial-grade products is generally between 8 and 100.

1. Chemical raw materials: Used as a substitute for formaldehyde in the production of synthetic resins, adhesives, pesticides (glyphosate, acetochlor), coatings, etc.

2. Pharmaceutical field: Pulp devitalizer, disinfection and antisepsis, biological specimen fixation.

3. Industrial disinfection: Fumigant disinfectant, bactericide, insecticide.

4. Other applications: Papermaking, fragrances, vitamin A synthesis, plastic and rubber additives.
