LOW DENSITY ORIENTED STRAND BOARD

摘要

A low density oriented strand board has an average density of less than abou t 1.5 times the density of wood species used in the board and a homogenous vertical density profile. Low density OSB may be formed by preheating the wo od finish prior to pressing, controlling the moisture content such that the cor e layer has a higher moisture content than the face layers, or a combination o f pre-heating and moisture content control.
