Paraformaldehyde (paraform, CAS 30525-89-4; (CH2O)n) is the solid polymerized form of formaldehyde and a source of formaldehyde gas on heating. Established uses include production of formaldehyde-based resins, wood preservation, leather tanning, and service as a disinfectant, fumigant and fungicide in industrial settings.
Frequently Asked Questions
What is the use of paraformaldehyde powder?
Paraformaldehyde is the solid polymerized form of formaldehyde and acts as a source of formaldehyde gas on heating. Established industrial uses include production of phenol- and urea-formaldehyde resins, wood preservation, leather tanning, and service as a disinfectant, fumigant and fungicide in industrial settings.
Is 4% paraformaldehyde the same as 4% formaldehyde?
Paraformaldehyde (CAS 30525-89-4) is the solid polymer (CH2O)n; dissolving and depolymerizing it yields a formaldehyde solution, so a 4% paraformaldehyde-derived solution corresponds to roughly 4% formaldehyde by weight. They are different physical forms of the same formaldehyde chemistry — one is the dry powder feedstock, the other the aqueous solution.
How to prepare a solution from paraformaldehyde powder?
Paraformaldehyde solutions are prepared by depolymerizing the powder in water, typically with gentle heat and a small amount of base to clarify, then adjusting concentration. Follow the SDS for handling; RawSource supplies paraformaldehyde 95% powder (CAS 30525-89-4) with CoA and SDS for in-house preparation.
What is the HS code for paraformaldehyde?
Paraformaldehyde classifies under HS code 2912.60. Verify the destination tariff line with your customs broker before importing.
What is the cost of bulk paraformaldehyde 95% powder?
Bulk pricing depends on volume, packaging and destination. Request a current quote from RawSource with your target quantity and ship-to location for landed pricing on the 95% powder.
