Let’s talk about rubber! There are a number of different types around the material rubber, which is an incredibly useful substance. Now, we will compare a certain kind of rubber - NBR (Nitrile Butadiene Rubber) vs EPDM. Both of these rubbers are used across countless products and applications, however they each have some distinguishing characteristics that make them unique. Now, which one suits you better? As I say it always depends on the use case! Read on to learn everything you need know about how the two types of rubber differ.
Before we move forward let us clarify what do we mean by NBR and EPDM. NBR is short for nitrile-butadiene rubber and EPDM is short for ethylene-propylene-diene monomer. Hah those are quite some large words, but fear not! In a nutshell, NBR and EPDM are two different rubbers that can be used in various shapes for whatever reason. One of the uses for this, is they can be turned into seals or gaskets which perform crucial function in several items
So now, let us talk about one of the largest variances between NBR and EPDM至 One of the only significant differences there is relating to how well they handle heat. NBR has excellent heat resistance properties hence resistant to breaking or getting damaged. This gives NBR excellent resistance against automotive engine heat, so it is a good elastomer for parts in engines such as gaskets and hoses.filters EPDM on the other hand is good because it remains pliable even when cold. This makes it a good fit for applications like weatherstripping and door seals, which need to keep cold air from getting into your house during the winter.
Moreover, these two rubbers are oppositely reactive towards various substances like oils and chemicals NBR, for instance is a material which is very immune to oil and grease. This is what makes it ideal for the seals of engines where oil needs to be contained. Conversely, Acids and alkalis are types of chemicals that EPDM resists better. Because of this EPDM is great for chemical rated pipes or tubing, as it wont break down very easily when exposed to chemicals.
If you want weatherstripping for a door or window, EPDM is probably the best choice. The reason for this is EPDM rubber, the material in PondPro's liquid pond liner formula that makes it flexible when cold to bond correctly as a seal with no damage during winter applications.
So let´s make some conclusions about NBR and EPDM. NBR and EPDM are two kinds of rubber that have their own advantages in working with difference requirements. While NBR can withstand high temperatures and is oil-resistant, EPDM works better in cold weather although it has even more resistance to acids and bases.
If you are deciding NBR or EPDM than give thought to the location and purpose of your rubber. If it is going to be in a hot environment, or near oil etc then NBR is the way to go. But if it will be in a cold area, or chemicals are involved EPDM would probably then the best choice for this case.
