Flexible open cell Polyurethane (PU) foam is one of the most versatile materials created. By adjusting the chemical composition and manufacturing parameters the resulting material can have widely varied attributes to address a wide range of application requirements from explosion suppression in aircraft to providing a comfortable night’s sleep in bedding. PU foams can be produced in different densities, firmness, resiliency, colors, absorbency, and other parameters that make it an ideal solution for many products. An added attribute of PU foams is that they are incredibly easy to work with. PU foam is a lightweight material that can be cut, molded or shaped to fit into any application. In addition, PU foam is often subjected to post-processing procedures to provide added benefits.
