Microcellular Polyurethane foam is an excellent gasket material for low squeeze applications where conformability is necessary. A typical application is a rectangular electrical enclosure that may have only four mounting points in its corners. Microcellular Polyurethanes such as Poron® will conform to an electrical box’s uneven sheet metal or plastic surfaces with the typical low squeeze applied by the box’s fasteners. Microcellular Polyurethanes’ extremely low compression set and quick return to its original thickness is also a perfect choice for applications such as door seals with variable gasket loading.
Microcellular Polyurethanes should be considered for any dust, moisture, or environmental seal that has challenging conditions such as low and variable loading and requires a positive seal over the life of the product.
