Light Density Polyester and Polyether Urethane Sponges and Foams have an open cell structure. The evenly spaced structure of these materials and a high proportion of open cells make them suitable for an infinite number of applications. The open-cell structure makes it highly flexible and conformable compared to its closed-cell counterpart.

Both types of urethane foams are strong, tough, and durable with excellent physical properties. They can be formulated to work equally well in some applications but there are applications where, after considering all the physical and environmental aspects of the application, one will be a better choice than the other.
The lists below are generally true of these types of urethane foams:
*When beginning your foam selection process, it is important to reference the information on the Technical Data Sheet to ensure that the appropriate foam type is being used to meet your application’s property requirements.
