Paraformaldehyde (PFA) is a high-purity solid polymer of formaldehyde with the chemical formula C2H6O2. It is supplied in white powder or granular form and offers a stable and concentrated source of formaldehyde for industrial applications.
Compared with aqueous formaldehyde solutions, paraformaldehyde provides higher effective formaldehyde content, improved storage stability, and lower transportation risk. Under controlled conditions, it releases formaldehyde gradually, making it an ideal raw material for resin production, agrochemical intermediates, pharmaceuticals, disinfectants, and fine chemical synthesis.
With consistent quality, reliable packaging, and suitability for long-distance shipment, paraformaldehyde is widely used by B2B customers requiring efficient, safe, and cost-effective formaldehyde supply.

Application
Paraformaldehyde is widely used as a raw material in the production of phenolic resins and urea-formaldehyde resins, providing a stable and high-purity source of formaldehyde.
C2H6O2 serves as a key intermediate in the synthesis of agrochemicals, including herbicides, pesticides, and fungicides.
Paraformaldehyde is applied in pharmaceutical and fine chemical synthesis, where controlled formaldehyde release is required.
C2H6O2 is used in the manufacture of disinfectants and biocides, contributing to effective antimicrobial performance.
Paraformaldehyde is utilized in textile and leather processing, such as finishing agents and anti-wrinkle treatments.
C2H6O2 is employed in laboratory and industrial chemical reactions as a convenient solid alternative to aqueous formaldehyde solutions.
