Title: Christoph Lohr: Innovator in Reactive Polyurethane Technology
Introduction
Christoph Lohr, hailing from Mettmann, Germany, is a prominent inventor known for his significant contributions to the field of polyurethane technology. With an impressive portfolio of 12 patents, Lohr has made notable advancements that focus on reducing environmental impact through innovative material compositions.
Latest Patents
Among his latest inventions, Lohr has developed reactive polyurethane compositions with a low residual monomer content. This invention describes reaction products derived from 2,4'-diphenylmethane diisocyanate, comprising at least 95 wt. % of the 2,4' isomer. By utilizing polyether-polyols and/or polyalkylene glycols, these compositions can be transformed into adhesive products that maintain a very low content of monomeric diisocyanate, specifically less than 0.5 wt. %, making them suitable for various applications.
Another notable patent by Lohr pertains to low-monomer polyurethane foams. This cross-linkable foamable composition is characterized by a low content of monomeric isocyanates, achieving its properties through a carefully controlled reaction process involving polyester diols and/or polyether diols with asymmetric and symmetric aromatic diisocyanates. The result is a composition with less than 0.1 wt. % of monomeric asymmetric isocyanate and below 2 wt. % of monomeric symmetric isocyanate.
