  • Wood fiber polymer composite extrusion and method
    Publication number: 20040142160
    Abstract: A method for extruding a thermoplastic polymer/wood fiber composite utilizes styrene acrylonitrile as the principal thermoplastic component. Acrylonitrile butadiene styrene is used as a stiffener and modifier to prevent degradation of a foaming agent's efficacy. The method of the invention and the extrusion produced by the inventive method are particularly applicable to extrusions having high aspect ratio cross-sectional shapes and extrusions in which the ratio of wall thickness to interior volume is large.
