Abstract: A suspending agent composition comprising (i) a fast hydrating guar gum and (ii) a high molecular weight polysaccharide, wherein the suspending agent composition has a rheological coupling ratio for yield point ranging from about 1 to about 2 when placed in an aqueous solution at a concentration of equal to or less than about 0.5 grams/deciliter and a ratio of about 90 weight percent (wt. %) fast hydrating guar gum and 10 wt. % high molecular weight polysaccharide. A wellbore servicing fluid comprising the suspending agent and methods of making and using the suspending agent.

Abstract: Compositions and processes for preparing extrudable powder blends containing at least one vinyl chloride resin and a cellulosic material are provided. More specifically, compositions and processes for preparing extrudable free-flowing powder blends containing PVC and wood flour (WF) are also provided for preparing foamed or nonfoamed extrudates. The processes provided herein incorporate components which may contain up to a total of 25 weight percent water. Processes for preparing foamed extrudates are also provided wherein a cooling fluid is used to increase the expansion ratio of the foam. Finally provided are composites having an extrudable thermoplastic substrate and at least one capstock layer disposed thereon containing a PVC/WF composition.
