Poron Foam Gaskets
Why Poron Foam Gaskets?
Alpha Die Cutting’s Poron foam gaskets have open-cell construction, which allows water, air, and gasses to be absorbed. This consistent microcellular structure with fine and consistent open cells makes Poron microcellular urethane an ideal dust gasket material making it suitable for many cleanroom applications. The Poron sheets and strips have an ultra-smooth texture for a sleek surface that’s easy to wipe down.
Poron urethane foam has excellent memory (compression set resistance) giving it a superior resistance to taking a compression set as compared to neoprene sponge or polyethylene foam. Compression at less than 2% at 73°F and less than 10% at 158°F makes Poron an ideal gasketing material for many indoor enclosure applications where dust, light, and incidental splash sealing are required. The average cell size of Poron foam is approximately 100 microns. The uniform, microcellular structure allows the poron gasket to be easily compressed for dust seals and cushions.

Shock Isolation Expert
Poron offers exceptional mechanical shock absorption combined with its low compression set making it an ideal material for shock isolation of battery compartments and sensitive electronics in hand-held devices. Even after extended compression, these high-performance polyurethane foams bounce back to shape faster than most other foams.
Versatile Across Industries
Poron is used in various industries including communications, automotive, electronics, and other industrial equipment and devices.
Exceptional deliveries
At Alpha Die Cutting we have agreed on a committed delivery for the Poron material from our suppliers of 3 business days delivery for most of the Poron material types and thicknesses. This enables us to manufacture a custom gasket within 6 business days max. Adhesive backings – Poron is available with plain backing or with a Pressure Sensitive Adhesive (PSA). Since Poron does not contain any plasticizers it does not reduce adhesive shelf-life. The integral skin surface provides a clean, readily bonded surface. The standard adhesive is Acrylic with a temperature range of -40 degrees to 190 degrees F.
Most grades of PORON foam are manufactured with a smooth skin on both sides.
