Latest Patents
One of his latest patents is a method and apparatus for the production of polyurethane foam. This invention involves mixing foam-forming chemicals to create an unfoamed liquid mixture, which is then fed into an open-topped trough. The design allows for a dwell time during which an exothermic and gas-forming reaction occurs, resulting in a partially foamed froth. The trough can be tilted to adjust the volume and dwell time, enabling continuous foam production without process shutdowns. Another notable patent focuses on producing fire-retardant polyurethane foams. This flexible foam is created by reacting an isocyanate with a polyol, incorporating a fire-retardant additive that includes melamine. This innovative approach enhances the safety and functionality of the foam products.
