Condensation reaction of PFL polymer
Polymerization reaction takes place within some hours at a temperature of about 95-100°C. The polymerisation is stopped by cooling when the target viscosity is reached.

Plywood panels testing & evaluation
Wood failure test
Shear strength test
Requirements of the EN314.2 standard
Free formaldehyde emissions: CARB II rule = 0.05ppm
According to CARB rule: 0.04ppm (ASTM E1333) corresponds to 0.3mg/L (F**** as per JIS A1460)

Conclusions• The BIOCORE lignin samples can give resins with adhesion performance
comparable to that of a standard PF.
• Phenol substitution levels up to 70% can be achieved with good results.
• Plywood panels produced with PFGL resin having up to 60-23 sub. Level of Ph.-F, can be classified as of class 3 panels (non covered - exterior use) .
• All plywood panels produced fulfill CARB II rule for free formaldehyde emissions.
• The new resins are less harmful for the environment and the people, while offer a solution for more sustainable products.
