Understanding Paraformaldehyde (PFA)

Paraformaldehyde (PFA), chemically designated as a polyoxymethylene glycol, is the smallest solid form of liquid formaldehyde. With the molecular formula HO(CH₂O)nH (where n typically ranges from 8 to 100), PFA presents itself as a white crystalline powder or prill with a characteristic pungent odor. The main competitive advantage of using solid paraformaldehyde over aqueous formalin solutions lies in its highly concentrated form (typically 91% to 96% purity) and extremely low water content.

By eliminating excess water carriage, downstream industrial syntheses gain higher yields, shorter process times, and reduced waste generation. The depolymerization of PFA releases gaseous formaldehyde under controlled temperature and catalytic conditions, serving as a clean initiator for various condensation polymerizations.

Critical Technical Parameters

  • CAS Registry Number: 30525-89-4
  • Molecular Weight: (30.03)n
  • Purity Grades: 92% Min & 96% Min (Industrial, Pharma-Grade available)
  • Free Acid Content: ≤ 0.03% (as Formic Acid)
  • Ash Yield: ≤ 0.05%

Global Sourcing & Industrial Solutions

Maximizing industrial efficiency with tailored high-purity solid aldehyde intermediates

Agrochemical Formulations

Paraformaldehyde is a critical building block in synthesizing key crop protection chemicals, including glyphosate, acetochlor, and butachlor. Sourcing dry, high-purity PFA ensures higher reactant concentrations and reduces wastewater processing costs in agro-synthetic plants.

Synthetic Resins & Plastics

Used to manufacture premium Phenolic Resins, Melamine Resins, and Urea-Formaldehyde Resins. Low-moisture PFA allows manufacturers to bypass the vacuum-distillation phase required with liquid formalin, accelerating overall batch run cycles.

Pharmaceuticals & Coatings

In the pharmaceutical field, high-purity paraformaldehyde is utilized as a disinfectant, sterilizing agent, and intermediate for synthesizing organic molecules. In coatings, it helps synthesize alkyd resins and cross-linking agents.

Industrial FAQ & Procurement Insights

Expert answers addressing the primary chemical, logical, and safety inquiries from technical buyers

What is the main chemical difference between Paraformaldehyde and Formalin?
Paraformaldehyde is a solid polymer chain of formaldehyde molecules with a typical purity of 91% to 96%. Liquid Formalin is a water solution containing 37% formaldehyde, with 10% to 15% methanol added as a stabilizer to prevent polymerization. Sourcing solid PFA eliminates water from reacting mixtures, resulting in higher product concentration, lower waste energy, and less equipment corrosion.
How does Shandong Runtai control the polymer length of its Paraformaldehyde?
We employ modern vacuum concentration and low-temperature control units. These maintain the average degree of polymerization (n value) within the 8 to 100 range. This ensures high dissolution rates at temperatures between 50°C and 80°C under acidic or basic catalytic environments, maximizing reactive efficiency.
What are the hazardous shipping regulations for Paraformaldehyde?
Paraformaldehyde is classified as a Class 4.1 flammable solid hazard under UN Number 2213. We use moisture-proof, anti-static woven bags lined with polyethylene, protected with thick pallets, and loaded into sealed ocean containers to prevent friction, heat, and moisture exposure.
What is the typical shelf life of Paraformaldehyde under warehouse storage?
The ideal storage shelf life is approximately 1 year from the date of manufacture when stored in a cool, dry, ventilated area. It must be kept away from open flames, heat sources, and strong oxidizers, acids, or alkalis. Prolonged storage above 30°C may lead to slow sublimation and product caking.
