Para Formaldehyde

We, Hir Primak Enterprise, are engaged in importing, exporting and supplying with excellent quality of Paraformaldehyde (PFA) which is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde is the solid form of liquid formaldehyde, formed by the polymerization of formaldehyde with a typical degree of polymerization of 8-100 units. Since paraformaldehyde is basically a condensed form of formaldehyde, it possesses the same characteristics but with a wider range of applications.

Uses

  • • The most important use of paraformaldehyde is in the production of many thermosetting resins, together with phenol, urea, melamine, resorcinol and other similar reagents.
  • • For production of lon Exchange Resins (chloromethylation reaction).
  • • Disinfection of the air in rooms.
  • • Many other chemicals/resins are manufactured from paraformaldehyde include dichloroethyl formal, methyl phenol, disinfectants, insecticides, pharmaceuticals such as vitamin A, embalming preparations, dyestuff and special plasticizers.
  • • Hardening of Glues.
  • • Manufacture of fluorescent pigments and soluble condensation product for textile auxiliaries, alcoholic solutions commonly known as ‘FORMOCEL’.
  • • In photography, paraformaldehyde is a gelatine hardener and accelerates development.
  • • It is a component of certain antiperspirant powders.
