More Information
Summary:A process for producing composite polymeric materials which comprise wood pulp fiber and thermoplastic polymer is provided, comprising the step of adding mineral oil to the composition containing wood pulp fiber and thermoplastic polymer during mixing. The wood pulp fiber used is preferably a bleached chemical wood pulp fiber. The process further includes conversion of the composite polymer materials into pellet form. La présente invention concerne un procédé de fabrication de polymères composites qui comprennent de la fibre de pâte de bois et un polymère thermoplastique, comprenant l'étape d'addition d'huile minérale à la composition contenant de la fibre de pâte de bois et le polymère thermoplastique durant le mélange. La fibre de pâte de bois utilisée est de préférence une fibre de pâte de bois chimique blanchie. Le procédé comprend en outre la conversion des polymères composites en pastilles.
