NAF (no added formaldehyde) and ULEF (ultra-low-emitting formaldehyde) certifications are required for many board products. Borregaard's sustainable biopolymers are compatible and complementary with many NAF systems and can be used to formulate ULEF resins, which meet regulatory requirements in the following resin applications:
- Particleboard
- Plywood
- Medium Density Fiberboard
- High-Density Fiberboard
- PMDI based wood adhesive systems
- Soy-based binder systems
- Glass and mineral insulation
Borregaard's biopolymers are viable alternative adhesive formulants. Different grades are available, with varying concentrations of cross-linkable functionality. This functionality includes aromatic groups, carboxyl groups and higher aldehydes. Simply by substituting a portion of the classic resin system with Borregaard lignin, emissions can be reduced. Borregaard biopolymers can be used in all types of water-based adhesive systems, including systems based on protein, sugar and PMDI.
Key benefits:
- Savings in operational expenses
- Increased performance
- Improved sustainability
- Safe to handle
- Easy to dissolve
