B. Dix et E. Roffael, MECHANICAL TECHNOLOGICAL PROPERTIES OF PA RTICLEBOARDS FROM HEARTWOODAND SAPWOOD OF LARCH, Holz als Roh- und Werkstoff, 52(5), 1994, pp. 341-341
Subject The properties of particleboards from heart- and sapwood of la
rch bonded with a binder based on diisocyanate (PMDI) were evaluated.
The results can be summarized as follows: Boards made from heartwood a
re always of lower thickness swelling than sapwood boards. The interna
l bond strength of the boards decreases with the age of the tree. Espe
cially the V100-value is very low for heartwood boards from 102-year-o
ld trees.
