| Foams are becoming attractive not only for reduced material consumption, which in turn lowers the cost of production, weight reduction and fuel savings but also; for developing a spectrum of new properties, which are the critical to qualities of specific applications. Polymer foam is polymer matrix with either air bubbles or air tunnels incorporated in it, known as either closed-cell or open-cell structure. Closed-cell foams are generally more rigid, while open-cell foams are usually flexible. Foams in the area of damping devices like in sports equipment or accessories which are exposed to high level of impact, can be manufactured with specially filled fluids called Shear thickening fluids (viscosity of fluids increases with increase in shear rate or stress). In building and construction for sealing and thermal insulation applications closed cell, sometimes crosslinked foams are being utilized. | ||

| 满足特定要求的泡沫生产的关键在于正确选择原材料和过程参数，后者管理体积膨胀，细胞大小和分布以及开放单元的含量。在IIT德里，正在进行研究，以调查和开发组成变化和加工参数对各种聚合物的泡沫性的影响，例如PP（商品聚合物），PLA（生物聚合物和可生物降解者）及其各种混合物和纳米复合材料通过使用物理吹动剂。靶向泡沫材料也通过各种泡沫表征技术开发。 | ||
