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 -

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.

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.
