Paraformaldehyde provides a solid formaldehyde source for resin manufacture and organic synthesis. Typically supplied as white powder, prills or granules, this relatively low-degree polymer releases formaldehyde when heated under appropriate conditions. Its applications include synthetic resins, adhesives and herbicide-related chemical manufacture. It should not be confused with the high-molecular-weight polyoxymethylene resins used as engineering plastics.

Low-Degree Formaldehyde Polymer: Paraformaldehyde is a polymer of formaldehyde with a relatively low degree of polymerization. It serves primarily as a solid source of formaldehyde for chemical processing.
Chemical Manufacturing Applications: Paraformaldehyde is used in resin production and organic synthesis, where formaldehyde is required as a reactant. Engineering-plastic heat resistance and mechanical strength are not applicable product characteristics.
Product Identification: Paraformaldehyde (CAS 30525-89-4) is typically supplied as a white powder, granules, or prills. It is distinct from high-molecular-weight POM engineering resins such as Delrin®.
Thermal Decomposition: Heating can cause paraformaldehyde to depolymerize and release formaldehyde gas. Formaldehyde is toxic, irritating, and carcinogenic; handling requires appropriate ventilation and protective measures according to the SDS.
Product Description of Paraformaldehyde CAS#30525-89-4
Paraformaldehyde, also known as polyoxymethylene (POM), is a high-molecular-weight polymer derived from formaldehyde, typically consisting of 8 to 100 repeating units. Long-chain polyoxymethylene is widely used in the manufacture of heat-resistant engineering plastics, commonly referred to as polyoxymethylene plastics (POE), and is commercially recognized under brands such as DuPont’s Delrin®.
Under elevated temperatures, polyoxymethylene decomposes readily and releases formaldehyde with a slight characteristic odor, making proper handling and processing conditions essential.
Product Application of Paraformaldehyde CAS#30525-89-4
Paraformaldehyde is mainly used in the production and use of herbicides, and is also used to make synthetic resins (such as artificial horn products or artificial ivory) and adhesives. It is also used in the chemical book pharmaceutical industry (active ingredients of contraceptive creams) and for the disinfection of pharmacies, clothes and beddings. Paraformaldehyde can also be used as a fumigant, fungicide and insecticide.

Dispersed PVC Resin
White fine powder
Polyvinyl chloride paste resin, also called dispersed PVC resin, is a fine white powder designed to disperse in plasticizers. Its small primary particles produce homogeneous plastisols for coating, impregnation, and casting. Applications include artificial leather, wallpaper, vinyl toys, gloves, automotive interiors, adhesives, and coatings requiring a workable paste-based processing route.![Xylene]( "Xylene")
XyleneXylene
Colorless liquid
Xylene is a clear, colorless aromatic hydrocarbon liquid with a characteristic odor. Insoluble in water but compatible with many organic solvents, it dissolves resins, oils, and rubber while providing useful evaporation behavior. It serves as a coating thinner, ink solvent, resin-processing medium, adhesive ingredient, and industrial cleaning solvent.![Ethyl acetate]( "Ethyl acetate")
Ethyl acetateEthyl acetate
Colorless liquid
Ethyl acetate is a clear, colorless ester solvent distinguished by its fruity odor and rapid evaporation. It mixes with ethanol, ether, and other organic solvents while having limited water solubility. Its solvency for oils, resins, and organic materials supports coatings, printing inks, adhesives, extraction, leather processing, and industrial cleaning.![Sodium Lauryl Ether Sulfate(SLES)]( "Sodium Lauryl Ether Sulfate(SLES)")
