  • CR 242 & EPDM 414 tape on electrical cabinets

    by Gordon Johnson
    The type of sponge rubber used for the seal depends greatly on the service application & the degree of “float" or tolerance variation. Doors that open and shut frequently needs a different seal to one that is closed and only opened for annual service or irregularly. Neoprene N42 is best for a regular opening applications, EPDM E41 super soft best for irregular openings

  • Fuel resistance of foams & sponge rubber-an explanation

    by Gordon Johnson
    The correct definition of   “fuel resistance”  is defined by the SAE (society of automotive Engineers ) & they have a standard test  SAE J18  which measure the degree of “swell “ in sponge rubber (Neoprene )  & plastics (EVA & PE) ,  when exposed to fuels. This “swell”  is indicative to the degree of stress cracking that will occur to a product over time. Stress cracking is the process of degradation or in  simplistic  terms, product failure.
