3. Applications and Functions

Polyoxymethylene is a common formaldehyde condensate with high thermal stability and easy formaldehyde release. It can be used as a solid formaldehyde source in various industrial processes, including:

1. Resin Synthesis

Can be used in the production of phenolic resin, urea-formaldehyde resin, etc., suitable for adhesive systems in wood products.

2. Casting Binder Systems

Compatible with cold-box and hot-box molding processes, participating in curing reactions.

3. Chemical Synthesis

Serves as a reactant in some organic synthesis processes, involved in the preparation of functional compounds.

4. Plastic Additive Components

Can be used in modified materials or crosslinking systems, helping to regulate product structure.

5. Coatings and Adhesive Systems

Suitable for specific formulations, acting as a helper component in coating reaction structure formation.

6. Leather and Textile Treatment

Useful in crosslinking finishing processes to support product structure stability.
