3. Applications and Functions

Formaldehyde is a chemical raw material commonly used in industry. It has reducing and reactive properties. Common applications include:

- Resin Product Manufacturing: Can be used to produce phenolic resin, urea-formaldehyde resin, melamine-formaldehyde resin, etc., involving adhesive formulation for engineered wood.

- Organic Synthesis Processes: Suitable for synthesizing pentaerythritol, 1,4-butanediol, paraformaldehyde, and other chemical intermediates.

- Industrial Treatment Agent Raw Material: Can be used in processes such as leather tanning, papermaking, and textiles.

- Textile Processing Additive Raw Material: Used in fabric finishing processes to improve wrinkle resistance or stiffness when combined with formulations.

- Adhesives and Coating Material Raw Material: In coatings, sealants, and industrial adhesive systems, it can participate in synthesis reactions and help form crosslinked structures.
