Title: Sven Barfoed: Innovator in Polyfuran Foam Technology
Introduction
Sven Barfoed is a notable inventor based in Copenhagen, Denmark. He has made significant contributions to the field of polymer chemistry, particularly in the development of polyfuran foams. With a total of 3 patents to his name, Barfoed's work has advanced the understanding and application of these materials.
Latest Patents
One of Sven Barfoed's latest patents is focused on the process of preparing polyfuran foams. This innovative method involves polymerizing or copolymerizing furfuryl alcohol, either alone or in combination with prepolymers or precopolymers of furfuryl alcohol. The process requires the presence of a liquid acidic compound, with the liquid feed material containing at least 20% of free furfuryl alcohol. Additionally, at least 50% of the hydroxyl groups in the mixture must be present as free furfuryl alcohol. The resulting polyfuran foam exhibits non-flammability characteristics as determined by the muffle furnace test.
Another significant patent by Barfoed details a synthetic foam and the process for its preparation. This involves a polymerized mass of at least 50 parts by weight of furfuryl alcohol, along with at least one part by weight of an amino compound such as urea, thiourea, or melamine, and up to 49 parts by weight of formaldehyde. The process also includes the use of fillers to enhance the foam's properties.
