  • Neoprene N42 & EPDM E41 tape on electrical cabinets

    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
  • Covid-19 & our EVA foam

  • What is the difference between EVA & PE foam

    What is PE foam & what is EVA foam

    When we talk about closed cell foams, we generally refer to PE (polyethylene) and EVA (ethylene vinyl acetate) However the end properties of a foam are only partly determined by the base resin and are also the result of the method of manufacture.

  • Electrical cabinet sealiing with neoprene tape to achieve an IP rating

    Experience has shown that Neoprene self adhesive tape is most successful achieving this IP seal when a constant compression rate in the neoprene tape  of 10% of its thickness occurs.

  • Fuel resistance of foams & sponge rubber-an explanation

    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.
