China Paraformaldehyde Suppliers - High-Quality Factory Production for Industrial and Laboratory Use

Paraformaldehyde is a white, crystalline polymer of formaldehyde that occurs as linear chains of formaldehyde molecules. Produced through the polymerization of formaldehyde gas under specific conditions and heat, this substance is highly soluble in water. When subjected to heat or treated with acids or bases, paraformaldehyde can be depolymerized back into formaldehyde. As a key ingredient, it finds extensive use in various industrial applications in China, especially in the manufacture of resins like phenolic and urea-formaldehyde resins, which are essential for adhesives, coatings, and composite materials. Paraformaldehyde also acts as a powerful disinfectant and preservative in laboratories and medical settings due to its excellent antimicrobial properties, making it a preferred choice among suppliers. Moreover, it plays a vital role in histology for efficient tissue fixation, showcasing its versatility and importance in both industrial and scientific fields, with numerous factories producing high-quality paraformaldehyde to meet global demand.

    Appearance

    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.
