Description: Binderless dry-formed hardboards were manufactured in the laboratory from refined Masonite pulp cooked for 2.5 minutes at steam pressures varying from 200 to 500 psi. Increasing steam pressure caused a general improvement in mechanical and physical properties except that linear expanaion increased with increasing steam pressures and that bending strength and stiffness peaked at 400 psi steam pressure. Statistical analysis shows that the fines content of the furnish, which increases with higher steam pressures, may be responsible for the improvement of board properties.
