The company offers specialized support for urea formaldehyde (UF) resin applications, covering raw material supply and process optimization. UF resin synthesis involves condensation of urea and formaldehyde (molar ratio 1:1.2 - 1:2.5) under alkaline (pH 7 - 9) then acidic (pH 4 - 6) conditions, with molecular weight control through reaction time (2 - 4 hours) and temperature (70 - 90°C). The company can assist in optimizing resin properties for specific uses:
- Wood adhesives: Viscosity 1000 - 3000 cP, gel time 60 - 120 seconds, for plywood and particleboard (bond strength > 1.0 MPa).
- Molding compounds: Filler-loaded (wood flour, talc) grades with high hardness (Shore D 75 - 85), low water absorption (< 1.5%), for electrical switchgear.
- Textile finishes: Low formaldehyde release (< 30 ppm) grades for wrinkle-resistant fabrics, using blocked formaldehyde technology.
Environmental solutions include formaldehyde scrubbing systems for resin production emissions (removal efficiency > 99%) and wastewater treatment (biological degradation of urea).
