Wholesale China Paraformaldehyde Suppliers - High-Quality Factory Production for Industrial and Laboratory Use Factories, Supplier
Paraformaldehyde, a white crystalline solid, is a polymeric form of formaldehyde made up of linear chains of formaldehyde molecules. Produced through the polymerization of formaldehyde gas under specific conditions and heat, this versatile chemical is highly soluble in water. When heated or treated with acids or bases, paraformaldehyde can be easily depolymerized back into formaldehyde. As one of the leading suppliers in China, our factory provides high-quality paraformaldehyde, widely used in various industrial applications such as the production of resins—including phenolic and urea-formaldehyde resins—which are essential for adhesives, coatings, and composite materials. Additionally, paraformaldehyde is known for its effective antimicrobial properties, making it an ideal disinfectant and preservative in laboratories and medical environments. It is also a crucial agent in histology for tissue fixation. Choose our factory for reliable paraformaldehyde supply and quality assurance.
Paraformaldehyde is a solid form of formaldehyde. It is often found in the form of small, granular particles or as a fine powder. It is soluble in water and commonly used as a source of formaldehyde in various applications. Paraformaldehyde can depolymerize to release formaldehyde gas when heated, making it useful for applications where a slow release of formaldehyde is required, such as in disinfection, preservation, and as a fixative in biological specimens. It is also used in the production of resins, plastics, and as a fumigant in agriculture.
