The effect of urea resins synthesized with different mole ratios on physical properties of high density fiberboards (HDF) and formaldehyde emission
The indispensable product of living spaces, the raw material of high density fiberboard (HDF) based derivative products (laminate flooring derivatives, etc.) are HDF boards. The test values (physical and formaldehyde emission properties ) of HDF boards are targeted both physical properties and forma...

The indispensable product of living spaces, the raw material of high density fiberboard (HDF) based derivative products (laminate flooring derivatives, etc.) are HDF boards. The test values (physical and formaldehyde emission properties ) of HDF boards are targeted both physical properties and formaldehyde emission E1 or E0 standard. In this study, 50% yellow pine (Pinus sylvestres L), 30% fir (Abies nordmanniana L), 20% beech (Fagus orientalis L) were used biomass. HDF boards of 7.7mmx2100mmx2440mm were produced on the production line which using three different moles of urea-formaldehyde resins (R; 1.17, X; 0.98 and Y; 0.88).
