ABSTRACT:
This invention is directed to an extrudable compound, an extrusion method using a polymer, a cellulosic fiber, and at least one lubricant selected from the group consisting of ethoxylated esters of hydantoins, ethoxylated esters of sorbitol and sorbitan, and ethylene bisamides made from fatty acids containing 6–10 carbons and composites manufactured through such processes which simulate conventional wood products.Another embodiment of the invention is directed to a composition containing polymer, a cellulosic fiber from an agricultural waste product and a lubricant containing a mixture of an alkylene bisamide derived from a C10–C18is fatty acid and an alkaline earth salt of a fatty acid.
