Understanding resin behavior during hot pressing of medium density fiberboard MDF is important to optimize panel properties. Before gelation, the mobility of the resin can affect its distribution and penetration on the wood cells during pressing. The resin in MDF boards occurs as coverage on the fibers surface and also penetrates within the fibers. In this paper, the effect of final resin content and physical—mechanical properties of MDF panels was measured under different conditions of press time, temperature and initial resin content. The measurements were performed by the Kjeldahl method. Results showed that a higher amount of initial resin led to a higher resin content in MDF boards.

Evaluation of UF resin content in MDF boards after hot-pressing by Kjeldahl method | SpringerLink

Indexing Jurnal Sylva Lestari :. This makes MDF suitable to partially replace solid wood, particularly for interior application. Approximately over than million m 3 of MDF are produced in , resulting in a large amount of waste MDF will be generated in the next 20 years. MDF is produced using urea-formaldehyde UF resins adhesive.

This study was conducted to evaluate the effect of panel density and resin content on properties of medium density fiberboard MDF to obtain some insights on MDF properties as a function of panel density and resin content. As the panel density and resin content increased, the internal bonding IB strength of MDF panel consistently increased. In physical properties, thickness swelling TS and water absorption WA decreased with an increase in both panel density and resin content.
