The differences between EPDM, neoprene and nitrile rubber foams
Many customers looking for rubber foams become confused when foam rubber suppliers invite them to choose between several high quality synthetic alternatives. Three such popular alternatives – EPDM, neoprene and nitrile – therefore deserve closer analysis.
EPDM and neoprene are perhaps the most similar to each other in terms of advantages to the user. Both are resistant to extremes in temperature; both are unlikely to crack when exposed for long periods in the open air; and both are highly tear-resistant. As such they each serve excellently as the main constituent in foam products, such as seals and gaskets.
EPDM, however, is more resistant to water than neoprene, making it a much more suitable alternative for applications such as sealing and protecting a flat roof, or in situations where a high degree of steam is anticipated.
Neoprene, on the other hand, performs better than EPDM when up against oil and grease, making it a more suitable alternative for automotive components such as engine filters.
Nitrile rubber meanwhile is, like neoprene, an effective material for situations where oil and grease are present. Nitrile does not, however, climb quite as far as neoprene in terms of resistance to high temperatures.
When it comes to rubber foam, UK companies currently make good use of all three of the above, so it is worth taking further advice and keeping an open mind on the relative merits of each for any particular applications.
