Compreg
Wood can be densified and its properties modified not only by filling its void volume with polymers, molten sulfur, or molten metals but also by compressing it under conditions such that the structure is not damaged. Compressed solid wood has been made in Germany since the early nineteen thirties and marketed under the trade name of Lignostone. These densified materials are used for textile shuttles, bobbins and picker sticks, for mallet heads, for forming jigs and for various tool handles.
Compreg is a phenol formaldehyde resin impregnated wood-veneer laminate; compressed under high heat and pressure to a high specific gravity, thus the properties of wood and a synthetic resin polymer network are combined.
Compreg is much more dimensionally stable than the best untreated compressed wood.
Products normally have mechanical properties higher than untreated wood due to their higher specific gravity.
Compreg is environment friendly and energy efficient.
High resilience, Low Weight, Low Thermal Conductivity, Aesthetic Appearance, Conforms to IS: 15476.
Compreg has been used for special purposes, such as concrete shuttering, deck, electrical insulation, fan blades, silent gears and aircraft parts
