Paraformaldehyde Powder (CH2O)N Purity 96% Polyformaldehyde Hazard Class 4
Polyformaldehyde is a kind of polymer, molecular formula is (CH2O)n, white amorphous powder, formaldehyde smell, linear polymer of formaldehyde. There is no fixed melting point, heating will decompose. Melting point 120 ~ 170℃. Easily soluble in hot water and release formaldehyde, slowly soluble in cold water, soluble in caustic soda and alkali metal carbonate solution, insoluble in alcohol, its high polymer insoluble in water. Formaldehyde-like reactions can occur, such as chloromethylation, forming acetals with alcohols and so on.

1. Paraformaldehyde is mainly used in the production and use of herbicides, but also used in the production of synthetic resins (such as artificial horn products or artificial ivory) and adhesives.
2. Paraformaldehyde is also used in the pharmaceutical industry (the active ingredient of contraceptive cream) and the disinfection of pharmacy, clothing and bedding, etc. Paraformaldehyde can also be used as fumigant, fungicide and insecticide.
3.Low degree of polymerization paraformaldehyde instead of ordinary industrial formaldehyde aqueous solution, in the synthesis of pesticides, synthetic resins, coatings and fumigation disinfectants and a variety of formaldehyde downstream products, can not only reduce the energy consumption of dehydration, but also greatly reduce the amount of wastewater treatment.
4.Low degree of polymerization paraformaldehyde because of its higher effective composition than industrial formaldehyde, is a solid particle, conducive to chemical, pharmaceutical and other chemical synthesis and other industrial applications, especially in the use of anhydrous formaldehyde as raw material synthesis, widely used.
5. Paraformaldehyde can also be used as disinfectants, fungicides, fumigants and herbicides, as well as in the manufacture of resins and artificial ivory.
