Products Description
Paraformaldehyde is the solid form of liquid formaldehyde. Classified as a thermoplastic, ParaFormaldehyde, Para Formaldehyde compound exhibits the typical characteristics of similar polymers with long-chain polyoxymethylene glycols, namely the ability to turn to liquid when exposed to heat and solidify upon cooling or being frozen to a hard, glass-like material. In fact, ParaFormaldehyde, Para Formaldehyde can be melted and cooled repeatedly and still retain its properties unchanged.

Application
- In coating applications, low acid content in paraformaldehyde is important for a greater gloss control and stability. Paraformaldehyde made with very low acid content in a chemical resistant environment can prevent formation of acidic by-products.
- In microbiology laboratories, fixation process (immunofluorescence) uses formalin 4% concentration. A blog by researchers mentioned that preparing this solution "fresh" from paraformaldehyde is better than using formalin that has been kept for some time. It is because more methylene glycol is present compared to its dimer and trimer oligomers and such solution of formalin 4% is absent of methanol.
- Paraformaldehyde can be used as a substitute of formalin to produce the resinous binding material, which is commonly used together with urea, melamine, phenol, resorcinol, tannin or other reactants in the manufacturing of particle board, fibreboard and plywood.
