Abstract

The org. fibre material of wood fibre, sea weed, straw or wood shavings etc, is pre-treated with an impregnating agent based on tar oil and bitumen, phenols, chlornapthaline, or urea formaldehyde condensates, prior to bonding and additional fillers. Pref. plastic fibres, splinters or shavings with a dia. >=0.3 mm are added.
