Paraformaldehyde (PFA)
High purity and stability Purity ≥96%, low free formaldehyde content (<0.5%), reduce side reaction risks, and ensure the quality of downstream products (such as resins, pesticides). Customized granularity selection Provide powder (60-80 mesh) or granules (2-5mm) forms, suitable for different production scenarios (such as powder coatings require fine particle size, and granularity is easy to feed). High reactive activity Fast depolymerization speed, efficiently release formaldehyde monomers in synthesis, and improve reaction efficiency (suitable for the production of ulotropine, phenolic resin, etc.)
