Advances in PHD Polyol Technology for Automotive Molded Flexible Foam

The application of high resilient (HR) polyurethane foam in automotive seating provides benefits for both the consumer and the manufacturer. The foam manufacturer benefits from the ease of production, cost effectiveness and design freedom. The major advantage for the consumer is the ability of HR polyurethane foam to give an initial soft «latex-like» feel at low deformations yet provide good support at higher deformations [1,2]. However, if only an unmodified polyol is used, this support is usually not sufficient for most TDI-based seat cushion applications at reasonable densities
