Paraformaldehyde is high formaldehyde content of solid formaldehyde, solid granular shape, easy to store and transport. At a higher temperature can become formaldehyde vapor, easy to replace high concentration of formaldehyde to participate in various reactions, is conducive to chemical, pharmaceutical and other chemical synthesis and other industrial applications, especially in the requirement of the use of anhydrous formaldehyde as raw material synthesis, widely used.

The main aspects are as follows: 

(1) pesticides: synthetic acetochlor, butylachlor and glyphosate; 

(2) Paint: synthetic high-grade automotive paint; 

(3) Resin: synthetic urea-formaldehyde resin, phenolic resin, polyacetal resin, melamine resin, ion exchange resin and various adhesives; 

(4) paper making: synthetic paper strengthening agent; 

(5) casting: casting agent, synthetic casting adhesive; 

(6) Aquaculture: fumigation disinfectant.

(7) Organic raw materials: used for the preparation of pentaerythritol, trihydroxymethyl propane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethylacrylamide, alkyl phenol, methyl vinyl ketone, etc.

(8) Others: medicine and disinfection.Used as raw materials for organic chemicals, synthetic resins, and also as pharmaceutical fumigants.
