GB13455 0.02Ash Content Urea Moulding Compound With 30% Melamine
Product description
The amount of urea-formaldehyde resin used to make plastic products accounts for only about 10% of total production. In the case of low molar formaldehyde and urea prepared urea-formaldehyde resin, and filler (pulp, wood powder), color, lubricant, curing agent, stabilizer (hexamethylenetramine, ammonium carbonate), plasticizer (urea or thiourea) and other components mixed, and then after drying, grinding, ball milling, screening, urea-formaldehyde pressure molding powder. The temperature and pressure of urea-formaldehyde plastics are 140~150℃ and 25~35MPa, and the pressing time varies according to the thickness of the products, generally 10~60min.
The polymer is non-combustible, water resistant, heat resistant, aging resistance, arc resistance, chemical corrosion resistance, with good insulation, gloss and mechanical strength, widely used in wood, plastic, paint, paper, textile and other industries

The product must be stored under neutral conditions. Linear UF resins can be cured at room temperature with ammonium chloride as curing agent. The molding powder is cured by heating at 130~160℃, and the curing process can be accelerated by accelerators such as zinc sulfate, trimethyl phosphate and diethyl oxalate. Urea-formaldehyde resin is mainly used in the manufacture of molded plastics, household goods and electrical components, and can also be used as board adhesives, paper and fabric sizing, laminating panels, building decorative boards, etc. Because of its light color and easy coloring, products are often rich in color.
