High-Quality Paraformaldehyde from China Suppliers - Trusted Factory for Resins and Laboratory Applications
Appearance:
Paraformaldehyde is a solid form of formaldehyde, It is often found in the form of small, granular particles or as a fine powder. It is soluble in water and commonly used as a source of formaldehyde in various applications. Paraformaldehyde can depolymerize to release formaldehyde gas when heated, making it useful for applications where a slow release of formaldehyde is required, such as in disinfection, preservation, and as a fixative in biological specimens. It is also used in the production of resins, plastics, and as a fumigant in agriculture.
Applications:
The applications of paraformaldehyde include:
-
1
Disinfection and Sterilization: Paraformaldehyde is used as a disinfectant and sterilizing agent in various settings, including healthcare facilities, laboratories, and industrial environments.
-
2
Agriculture: It is used as a fumigant and preservative in agriculture to control pests, fungi, and bacteria in stored agricultural products and soil.
-
3
Production of Resins: Paraformaldehyde is a key raw material in the production of resins, such as phenol-formaldehyde and urea-formaldehyde resins, which are used in the manufacturing of wood products, adhesives, and coatings.
-
4
Chemical Synthesis: It is used as a source of formaldehyde in various chemical reactions and synthesis processes.
-
5
Biological Fixative: Paraformaldehyde is used as a fixative in biological specimen preparation for microscopy and other laboratory analyses.
Packages:
Packed in 25kg Hazardous chemicals packaging bags
Characteristics:
Chemical Structure
It is a polymer of formaldehyde, typically existing as a white, crystalline powder. Its structure consists of linear chains of formaldehyde molecules.
Solubility
Paraformaldehyde is soluble in water, and upon heating or in the presence of acids or bases, it can depolymerize back into formaldehyde.
Melting Point
It has a melting point of around 150-160°C (302-320°F), which can vary depending on the degree of polymerization.
Reactivity
Paraformaldehyde is reactive and can release formaldehyde gas, which is a known irritant and potential carcinogen.
Antimicrobial Properties
It exhibits effective antimicrobial properties, making it useful as a disinfectant and preservative in laboratory and medical settings.
