Production and Properties of Isocyanate-Bonded MDF Manufactured from Acacia Mangium
Medium density fiberboards (MDF) were manufactured from fast-growing Acacia mangium wood. The boards were produced at two levels of density, 600 and 750 kg/m³. Isocyanate and urea- formaldehyde resin adhesives were used asbinders. The physical, mechanical and dimensional stability properties we...

| description | Medium density fiberboards (MDF) were manufactured
from fast-growing Acacia mangium wood. The boards were
produced at two levels of density, 600 and 750 kg/m³.
Isocyanate and urea- formaldehyde resin adhesives were used
asbinders. The physical, mechanical and dimensional
stability properties were determined according to JIS 5906.
Both adhesive and density affect significantly the
properties of boards tested. It was found that the higher
the density, the better the quality of the boards.
Isocyanate bonded boards showed higher strength and more
stable than urea - formaldehyde bonded boards, even when
used at lower percentage of resins, 3 % and 13 %,
respectively. It was also found that isocyanate bonded
boards at low density had properties meeting the Japanese
Industrial Standard, JIS 5906, Type-150 board whereas at
high density (750 kg/m³), the boards met the Type-200. The
properties of urea-formaldehyde bonded MDF also met JIS
Type-150 for the lower density and Type-200 for the high
density boards, but MOR in wet condition failed the
standard. |
