Abstract

A low density paper or cardboard is formed by introducing a polymerisable or polycondensable filler material (e.g. phenoplasts, aminoplasts, expoxy resin, polyvinyl, polystyrene, polyurethane, polyolefine, cellulose-acetate) in the fibre mass of the paper and expanding it (e.g. during polymerisn. or polycondensations, by a plastisol or by terminal decompsn) in situ. The filler material may be in the form of fibres and granules and may be impregnated into an already formed paper sheet or being introduced into the paper pulp. The filler material may contain additives and be bonded to the surface of the paper fibres. The paper is cheap light and cheap to transport.
