UF Urea Formaldehyde Powder

Industry Base Urea Molding Compound Raw Material

 

what is Urea formaldehyde

 

Urea formaldehyde is a translucent thermosetting resin made by heating urea and formaldehyde in ammonia or pyridine solution. It is widely used as a component of molding materials, adhesives and protective topcoats.

The fiberboard industry is a big consumer of resin, where it is used as an adhesive. Although it has many advantages, it can still release formaldehyde gas under certain conditions. These resins can be used as viscous

liquids or spray-dried powders, and water needs to be added before use.

 

CAS 108-78-1 PH 7.5 Value Melamine Raw Material UF Urea Formaldehyde Powder 0

 

The English abbreviation UF. Cross-linking occurs during processing and molding, and the product is an insoluble and infusible thermosetting resin. The cured urea-formaldehyde resin is lighter in color than phenol-formaldehyde resin,

translucent, resistant to weak acids and weak bases, good insulation performance, excellent abrasion resistance, and low price. Urea and 37% formaldehyde aqueous solution can be polycondensed under the catalysis of acid or alkali

The linear urea-formaldehyde oligomer is obtained, which is industrially used as a catalyst to react at about 95°C, and the molar ratio of formaldehyde/urea is 1.5 to 2.0 to ensure that the resin can be cured.
