Applications

In industry: chemical raw materials herbicides, insecticides, fungicides, disinfectants, high-grade coatings, dyes, synthetic resins, papermaking additives, developers and other raw materials.

In the application of new materials: after the depolymerization of polyformaldehyde, formaldehyde is formed in solution, which can be used as fumigant, disinfectant, fungicide and fixative.
