Cellulosic fibers derived from a chemical wood pulp were added to low density flexible and rigid foams in weight fractions ranging from one to five parts-by-weight (pbw) of the polyol. Foams containing no fibers or milled glass fibers at five and ten pbw were used for comparison. Evaluation of selected properties of the foams revealed that low weight additions (2 pbw) of a fluffed cellulose fiber resulted in generally improved properties over foams containing no fibers, glass fibers, or an expanded cellulose fiber.
