Paraformaldehyde Chemical Properties:

Paraformaldehyde is a polymerized form of formaldehyde (CH,O) and is a stable white crystalline powder. Irritating odor. Because pure formaldehyde is unstable at ambient conditions, paraformaldehyde is used as a readily-usable form of formaldehyde at use sites. Then,formaldehyde gas is generated during heating. Paraformaldehyde is used for different applications as a source of either gaseousformaldehyde or solution formaldehyde.


Paraformaldehyde Storage:

Recommended storage temperature 2-8℃.

Handle and store under inert gas. Moisture sensitive.

Paraformaldehyde Package:

25kgs bag, 20 tons in one 20ft container with pallets


Paraformaldehyde Application

  • Used as a agricultural chemical, fungicide, bactericide, and wood preservative.

  • The polymerized form of formaldehyde, used in root canal sealers that provide antimicrobial activity.

  • Used as a fumigant, a disinfectant and in the manufacture of synthetic resins like melamine resin, phenol resin and polyacetal resin.

  • Used in cell culture. It also serves as a fixative in electron microscopy.

  • Used in the preparation of formalin fixatives for tissues or cells.
