Flexible polyurethane foams
Flexible polyurethane foams are one of the most important classes of cellular plastics used in the production of materials such as sponges, memory foams, pillows, furniture, automotive upholstery materials, packaging, footwear, and more. The total consumption of flexible polyurethane foam was estimated at over 7 million tons in 2007, with an average annual growth rate of about 5%. In general, industries that manufacture flexible polyurethane foams use fillers to modify the properties of the material in specific ways to achieve dimensional stability, easy mold release, and service density. The production cost of flexible polyurethane foam largely depends on the cost of polyols, which make up the highest percentage of the materials used in foam production and are characterized by their ability to induce superior mechanical properties. Suitable fillers that are relatively inexpensive can be incorporated into the foam matrix as a replacement for polyol. The influence of CaCO₃ filler in the flexible polyurethane foam matrix serves a dual purpose of achieving sustainable mechanical properties and reducing production costs. It was found that the optimal composition of CaCO₃ is 20 wt.%, which simultaneously represents a production cost reduction of 18.54%. In flexible polyurethane foams, fillers promote an increase in density and compression resistance.
