Granular Material Urea Formaldehyde Moulding Compound For Plastic Toilet Cover
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.
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.
Applications:
Powder for tableware, bowl, cup, plate, cover of bottle;
Granule for electrical switches,plugboard, lampholders, low-voltage appliances, dash-board.etc.
Storage:
Storage: Kept in airy, dry and cool room.
Storage period: six months from the manufacturing date. Test should be undertaken when expires.
Qualified products can still be used.
Transportation Caution: avoid moisture, heat, dirt and packaging damage.
Package: plstic knittin bag with inner wet-proof plastic bag.
