PROCEDE POUR LA PRODUTION DES FEUILLES A PARTIR D'UNE MELANGE DE FIBRES VEGETAUX ET DE POLYOLEPHYNES

摘要

Manufacture of sheets having a high resistance to water absorption by hot calendering of a mixture produced from 25 to 75% by weight of vegetable fibres and from 75 to 25% by weight of molten polyolefine. As unexpected, such a mixture does not stick to the calender rolls during the sheeting step.
