GENERAL INFORMATION

492P is a 5 mil porous film produced from Ultra High Molecular Weight (UHMW) polyethylene . The process yields a highly uniform pore structure in the x, y and z directions. The film has been rendered Hydrophilic by plasma treatment. 492P is an open cell, tortuous path structure wirth a void volume of 25 to 35%. Application areas would include filtration, diagnostics, wicks and support media for finer membrane structures where porosity, chemical inertness and mechanical strength are important.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
