PVC plastisols were formulated with silicone surfactant, mechanically shipped to form froths, and oven‐fused to form open‐cell foams. These were much softer than conventional chemically‐blown foams which contain mixtures of open and closed cells. Increasing plasticizer content and decreasing foam density also had the expected softening effects on foam properties.
