Latest Patents
One of Heimo Ludke's latest patents is a process for the production of fiber-containing polyurethane moldings. This invention allows for the creation of polyurethane moldings with an inhomogeneously colored surface, featuring color contrasts in a fiber-like distribution. The process involves incorporating colored fibers of a specified type into a polyurethane forming reaction mixture. These fibers must meet specific criteria, including a staple length of 0.1 to 6 mm and a denier of 0.1 to 25 dtex. The coloring agent used must not migrate or dissolve in the polyurethane-forming materials. The fibers are typically used in quantities representing 0.1 to 10 wt. % of the reaction mixture. Examples of moldings produced using this process include shoe soles, shoe heels, multiple layer soles, and padded components.
Another significant patent by Ludke is a process for the production of non-cellular molded articles. This process describes the successive production of at least two non-cellular molded articles that differ in their mechanical properties. Both articles are based on organic polyisocyanates, which are trimerized in the presence of compounds reactive with isocyanate groups. The equivalent ratio of NCO groups to reactive groups is varied within the range of 1:0.8 to 1:0. In a second embodiment, a uniform article is produced with anisotropic mechanical characteristics that vary continuously and/or stepwise.
