The prepolymer crystallises slowly at room temperature.
When the NCO/OH ratio is higher than twice the stoichiometric ratio, the resulting product (named semi - or quasi-prepolymer) possesses a large excess of non reacted free isocyanate.
Bush also played an important role in the development of the flexible polyurethane foam and furniture industries through his service as a founding member of the PFA, through his involvement with the International Sleep Products Association (ISPA), and as president of the American Furniture Manufacturers Association’s Suppliers Council. He received the Exceptional Service Award and the Robert MacMorran Award from ISPA, and was inducted into the American Furniture Hall of Fame in 2006.
on the Formation of Polyurethane Prepolymer ..
Robert Schiffler was an engineering innovator. He and his technical staff at Fecken-Kirfel, through their combined efforts, with creativity, ingenuity and vision contributed tremendously to the acceptance of new slabstock products, and thereby, the rapid growth of the flexible polyurethane foam industry.
Robert Hay began his career in the early 1950's as a chemist with Firestone Tire and Rubber Company. His early work concentrated on applied research and development related to latex foam. In 1955, Hay was assigned to a task group that developed vinyl covered polyester-based polyurethane foam dashboard pads for Ford and General Motors. This was one of the first large volume applications of prepolymer polyurethane foam in the U.S.
In this prepolymer system, the reactivity is independent of …
Richard Tucker, Sr. led Wm. T. Burnett Company's venture from garneted cotton batting into early polyurethane foamproducts. While he ardently shares credit with all Wm. T. Burnett employees, Richard Tucker is a true pioneer and wasa leader in the development of commercially viable polyurethane foam products.
While still in his early 20's, Tucker saw the development of the first continuous pouring machine, built in 1954 forBurnett in the Bayer laboratories in Germany. The massive equipment had a reciprocating pour head and laid the prepolymermixture into waxed pans that traveled beneath the pouring head on a conveyor.

Prepolymer Preparation - Werner
Beamech has been involved in many major innovations including early equipment designs to support the continuous processing of flexible polyurethane foam products. Today, the company supplies conventional, Maxfoam, Vertifoam and Ultima foam processing equipment, flat topping systems, bulk tank farm equipment and liquid carbon dioxide systems, as well as rigid foam laminators and rigid slabstock machinery. Beamech was awarded several patents for its processes and equipment, including the continuous variable pressure foaming process and equipment (VPF) and CO2 vertical round block equipment.
with industrial polyurethane products
Warren Neill Pollock was responsible for the design and setup of one of the first commercial flexible polyurethane foam manufacturing operations in the United States, at Curtis Wright Corporation, in the 1950s. After he joined General Foam Fabricators, Inc., Pollock led the development of the round, or cylindrical, foam block processing that greatly expanded the capabilities of the FPF industry. The capacity to peel continuous thin sheets of foam for laminated fabrics made tremendous savings possible in raw materials and product.
are suitable for polyurethane prepolymer synthesis.
Early in his career, Karl Lens moved from vinyl to the polyurethane foam business. In 1959, Karl and his partner, Irving Rifkin, founded Crest Foam Industries, Inc., in Flushing, New York, which produced and peeled thin gauge polyester foam primarily for flame lamination to fabric for the garment industry. Crest Foam, now a division of British Vita, was the second U.S. producer of thermally reticulated foam, and was a dominant regional supplier and one of the most diversified and technologically advanced foam companies in the United States.

Jerry Pool’s career in the foam industry took him around the U.S. – and around the world – where he solved production challenges and addressed air quality and environmental issues with innovations and improved process technologies. In the United States, Pool worked at NOPCO Chemical Company in Chattanooga, Tennessee; Diamond Shamrock in New Jersey and Chattanooga; Flexible Foam Products in Ohio; Clark Crain Foam in Chicago; Leggett & Platt Urethane Foam Division in North Carolina and Mississippi, and Future Foam in High Point, North Carolina. In 1993, Pool established a consulting business which focused on environmental and OSHA compliance, polyurethane process and machinery technology.
Preparation of a Novel Prepolymer of Polyurethane Acrylate
In 1958, he became a polyurethane chemist for the Scott Paper Company, later working on products for the Technical Products Group of the Foam Division with the late Robert Volz – also a PFA Hall of Fame Member – and the inventor of reticulated polyurethane foams.
