Title: Otto Plewan: Innovator in Molding Compositions
Introduction
Otto Plewan is a notable inventor based in Neuotting, Germany. He has made significant contributions to the field of molding compositions, holding a total of 5 patents. His work primarily focuses on the development of sinterable materials that have applications in electric cells.
Latest Patents
Among his latest patents, Plewan has developed a sinterable, finely particular molding composition based on vinyl. This molding composition is essentially composed of a mixture of at least two polymers based on vinyl chloride and at least one water-soluble surfactant. One of the polymers is a sinterable vinyl chloride/alkyl acrylate copolymer, which can also contain polymerized units of vinyl acetate and ethylene. Additionally, at least one further polymer is a vinyl chloride polymer that can contain up to 5% by weight of polymerized units of vinyl acetate and ethylene. This innovative molding composition is particularly suitable for producing sintered, porous, flexible moldings, especially separator compartments for electric cells.
Another significant patent involves a sinterable, finely divided molded material based on polyvinyl chloride. This molding material is composed of a vinyl chloride (graft) copolymer, at least one anionic and/or nonionic emulsifier, and, if appropriate, small quantities of additives. The vinyl chloride (graft) copolymer contains 95 to 70% by weight of polymerized units of vinyl chloride, 5 to 30% by weight of polymerized units of an alkyl acrylate having 3 to 10 carbon atoms, 0 to 7% by weight of polymerized units of ethylene, and 0 to 15% by weight of polymerized units of vinyl acetate. This molding material is also suitable for the production of flexible, sintered moldings, particularly separator plates for electric cells.
