Application of renewable hydrophobic formulations for wood composite panel manufacturing

Purpose and goal:

This mobility project was built on previous collaborations between Linnaeus University and IKEA on the replacement of petroleum-based additives and adhesives in wood-based products, e.g., fibreboard panels. The scientific objective of this project was to develop knowledge on the performance of tall oil-based hydrophobic formulas and evaluate the optimum application condition for manufacturing more sustainable wood composite panels through a constant knowledge transfer between academia (Linnaeus University) and industry (IKEA).

Expected results and effects:

The hydrophobic effect of tall oil-based formulas was precisely evaluated by analyzing their behaviour at different influencing factors, including various emulsification chemistries, matrices, and application parameter conditions. The results emphasised that the mechanical properties of the panels were slightly affected by the influencing factors, while the modification of tall-oil-based hydrophobic formulas resulted in considerable alterations in the water resistance of the fibreboard panels.

Approach and implementation:

The project followed a stepwise approach to provide an understanding of the application of the tall oil-based hydrophobic formula in fibreboard panels at various manufacturing parameters and pressing conditions. Moreover, an industrial integration framework was designed in the project to evaluate the outcome and define the required steps for further utilization of the results.

Overall, the project demonstrated the great potential for industrial implementation of the results by creating relevant fundamental knowledge, which resulted in the formation of the TallBoard project.
