3.Product Feature And Application of Paraformaldehyde

1) paraformaldehyde is mainly used in the production and use of herbicides, but also used in the production of synthetic resin (such as artificial horn products or artificial ivory) and adhesives. Paraldehyde is also used in the pharmaceutical industry (an active ingredient in contraceptive cream) and in disinfecting pharmacies, clothing and bedding.

2) Paraformaldehyde can also be used as a fumigant disinfectant, disinfectant and insecticide.

3) Low degree of polymerization of paraformaldehyde instead of ordinary industrial formaldehyde aqueous solution, in the synthesis of pesticides, synthetic resin, paint and fumigation disinfectant and other a variety of formaldehyde downstream products, can not only reduce the energy consumption of dehydration, but also greatly reduce the amount of wastewater treatment, which is a green environmental protection project for the benefit of the country and the people.

4) Low degree of polymerization of paraformaldehyde is a solid particle because of its higher effective composition than industrial formaldehyde, which is conducive to chemical, pharmaceutical and other chemical synthesis and other industrial applications, especially in the requirements of the use of anhydrous formaldehyde as raw material synthesis, widely used.

5) It can also be used as disinfectants, fungicides, fumigants and herbicides, as well as in the manufacture of resins and artificial ivory.

4. Product Details of Paraformaldehyde 

Polyoxymethylene (IUPAC named Polyoxymethylene, POM) is a formaldehyde polymer (high molecular weight polyformaldehyde), generally having a structural length of eight to one hundred single Chemicalbook bits. Long chain paraformaldehyde is commonly used in heat-resistant plastics, also known as polyformaldehyde plastics (POE, Derlin from DuPont). Poly - formaldehyde decomposition fast, will release a slightly smelly formaldehyde.
