Poron foams are used for sealing, gasketing, sound dampening, vibration isolation, and shock absorption. Made by Rogers Corporation, these open-cell urethanes absorb energy and exhibit low outgassing and low compression set. Poron foam materialis inherently flame retardant, and does not contain plasticizers and residual chemicals that can contaminate devices or promote embrittlement. By understanding the features and benefits of Poron cellular urethanes, you can determine whether Poron is right for your application.
Material Properties
Low compression set, which means that this open cell foam won’t lose the ability to self-expand after being subjected to normal compression cycles.
Poron gaskets won’t remain permanently deformed after an applied force is removed.
Poron cellular urethanes also absorb mechanical shock, which makes them a good choice for indoor enclosures, battery compartments, and electronic devices.
Indoor vs. Outdoor Applications
In general, sealing with Poron gaskets improves as compression set and gasket material width increase. Poron is not recommended for outdoor enclosures, however, and heavy rain or standing water may cause wicking. This open cell foam is not the best choice for some low and high temperature conditions either, so some buyers may require seals, gaskets, or insulation made from silicone, neoprene, or EPDM instead.

Die Cutting Tolerances and Tooling Considerations
With die cutting, tight tolerances are achievable, but product designers may need to balance die cutting tolerances with die cutting costs.
With its fine, consistent microcellular structure, Poron urethanes are often used as dust gaskets in cleanrooms and in medical applications.
This high-density polyurethane foam also meets UL flammability standards.
Resists many petroleum products, automotive fluids, and chemicals.
Because Poron does not contain plasticizers, this microcellular foam has a good shelf life and a clean surface for bonding.
