Title: Innovations of David Paul Hultman

Introduction

David Paul Hultman is an accomplished inventor based in Munising, MI (US). He holds a total of 4 patents that showcase his contributions to the field of polymer-reinforced materials. His innovative work has significantly impacted the development of stronger and more efficient paper products.

Latest Patents

One of Hultman's latest patents involves a method of forming polymer-reinforced paper that exhibits improved cross-direction tear. This process includes preparing an aqueous suspension of fibers, with at least 50 percent being cellulosic fibers by dry weight. The suspension is distributed on a forming wire, and water is removed to create the paper. The paper is then treated with a polymer-reinforcing medium containing a bulking agent, which can range from 15 to 70 percent by weight based on the dry weight of the cellulosic fibers. The bulking agent may be a polyhydric alcohol or a polyethylene glycol with a molecular weight between 100 and 1,500. The resulting polymer-reinforced paper demonstrates enhanced cross-direction tear when tested with an Elmendorf Tear Tester, particularly when the moisture content is no greater than 5 percent by weight.
