Shockproof Sponge PORON Foam Sheet

PORON is a fine pitch open-cell urethane foam produced by Rogers Corporation. The uniform, the microcellular structure allows PORON to be easily compressed for dust seals and cushions. Water sealing with PORON is possible in applications with proper compression and moderate water exposure. The average cell size of PORON foam is approximately 100 microns.

PORON cellular urethane foam was engineered to have an excellent memory (compression set resistance). The compression set resistance of PORON makes it a top pick for sealing and cushioning electronics.

PORON urethane foam is manufactured by continuously casting and curing mechanically mixed formulas to the desired thickness.

PORON foam tape is using PORON foam as backing material and coated with one side or two-sided different kinds of adhesives.


  • Low compression set - PORON cellular urethane has superior resistance to taking a compression set as compared to neoprene sponge or polyethylene foam. Less than 2% at 73°F and less than 10% at 158°F makes PORON an ideal gasket material for many indoor enclosure applications where dust, light and incidental splash sealing are required.
  • Energy absorbing - PORON's ability to absorb mechanical shock vibration combined with its low compression set make it an ideal material for shock isolation of battery compartments and sensitive electronics in hand-held devices.
  • Consistent microcellular structure - Fine and consistent open cells make PORON microcellular urethane an ideal dust gasket material, suitable for many cleanroom applications.
  • Adhesive backings - PORON readily accepts most of the pressure-sensitive adhesive offerings. Since PORON does not contain any plasticizers, it does not reduce adhesive shelf-life. The integral skin surface provides a clean, readily bonded surface.
  • Thickness options - PORON is available in a wide range of thicknesses. Offers bonded layers to achieve non-standard thicknesses and stacked/bonded assemblies.
  • Smooth skin - Most grades of PORON foam are manufactured with a smooth skin on both sides. The supported products have a 1 mil PET film bonded permanently to one side.
