Latest Patents
One of Schumacher's latest patents is titled "Process for the production of molded products using internal mold." This process involves reacting an organic isocyanate component with an isocyanate reactive component. If the isocyanate component is based on a prepolymer of an isocyanate and a fatty acid ester, then the isocyanate reactive component must contain a fatty acid. Alternatively, if the isocyanate component contains a fatty acid, then the isocyanate reactive component must contain a zinc carboxylate. This innovative system is designed to release from bare steel.
Another significant patent is "Mold for the preparation of reinforced reaction injection molded products." This mold consists of an upper and lower mold part that define a mold cavity when closed. A channel surrounds the cavity, and one upper edge of the channel forms part of the outer edge of the mold cavity. The channel is partially filled with an elastomeric material, and a shear plate is attached to the other part. When the mold is closed, the shear plate presses against the elastomeric material, allowing gases to escape from the mold cavity.
