Polyurethane foams (PU) are used in many automotive applications due to their durability and sound absorption properties. This paper examines the effects of reusing predominantly silica‐filled thermoset composites as a reinforcing agent when ground to a particle size less than 106 μm (0%, 2.5%, 5%, 7.5% by wt%) on mechanical, physical, thermal, and sound absorption properties of PU foam. Young's modulus...
In this study, flexible polyurethane foam samples were prepared using concentrations of up to 50% of two novel polycarbonate polyols, Polyol D 251‐20 and Polyol D 351‐30, derived from the copolymerization of carbon dioxide (CO2) and epoxides, to determine whether the final foam products meet automotive standards for use in seating applications. In other words, CO2‐based polyols were substituted for...
