Utilizing biofillers to create low-isocyanate foam with good mechanical properties

an iowa state university research team has developed a method to create low-isocyanate polyurethane foam using biofiller recycled from landfills. they said the foam’s stability and compressive modulus were improved. this foam is made from bio-based polyols. to achieve the foam hardness typically imparted by isocyanates and avoid foam collapse, they used a prepolymerization step.…
