Latest Patents
One of Pisaric's latest patents is for biologically degradable leather, which is a groundbreaking advancement in sustainable materials. This invention involves polyurethane ureas that can be synthesized through the reaction of a hydrophilic NCO prepolymer. This prepolymer is derived from a polyhydroxy component that consists of 9 to 100% by weight of a polyether, which contains 30 to 100% by weight of ethylene oxide. The process also includes a mixture of hydrophilic and hydrophobic NCO prepolymers, which are reacted with an aldimine or ketimine-containing hardener mixture in the presence of water and organic solvents. Approximately 30 to 70% of the NCO groups of the prepolymers are reacted with the amino groups of the hardener, while the remainder reacts with water. This innovative approach not only enhances the properties of the material but also contributes to environmental sustainability.
