Difference Between NBR and EPDM rubber

A lot of people want to understand the difference between NBR rubber and EPDM rubber. They have very similar characteristics but can be used in different conditions. Let’s describe them in detail.

NBR rubber

NBR rubber has a lot of advantages. It has high resistance to swelling in relation to benzene, oils and fats. There are a lot of spheres where NBR is so useful. They are hydraulics, engine building, machine building, oil industry, apparatus building.

One more advantage of this material is the low price.

But you need to understand that it isn't resistant to high temperatures. But the level of temperature resistance depends on the ACN percentage. You can easily choose the level of this substance for your conditions.

Let’s describe rubber materials that are produced by Kauchuk Rubber.

Basic properties of NBR rubber

The most important characteristics of this material are high hardness and resistance to abrasion. Despite the narrow corridor of permissible temperatures, they are appropriate for most goals. But we recommend not to use this material when the temperature is above 80 degrees.

The less temperature, the better NBR rubber properties are. The best temperature is about 5 degrees below zero. Kauchuk Rubber proposes different types of NBR rubbers by the quantity of the ACN in their composition. It offers low, medium, high and very high ACN amounts.

When NBR Rubber is used?

Usually NBR is used in the spheres that need high elasticity and low permanent deformation. For example, in the sealing technique or as a pretensioner for less elastic substances. It can be used for:

1. Wipers. But only for special situations.

2. Rod and piston seals for low pressures.

3. Shaft seals.

4. O-rings.

EPDM rubber

EPDM rubber is used for producing shockproof polypropylene, different products of rubber, for insulating wires and cables. EPDM can be used autonomously or in combination with other kinds of rubbers. For example, it is necessary for creating tires and some details made of polypropylene.

Also this substance is used in residential buildings. There are many appointments of it in construction. For example, as a sealant, waterproofing or roofing. Also you can see it in modern children’s and sports grounds.

Basic properties

It has a wider corridor of allowed temperatures. They are more resistant to high and low temperatures and can be used between -50 and +150 degrees. In other cases they are similar in characteristics to NBR rubber. They are resistant to ozone and have great dielectric properties.

To sum up, EPDM rubber is greater when you want to use it in more extremal temperature conditions. If you want to buy qualitative rubbers, go to the site https://kauchuk-rubber.com/ and contact managers via the contact form.
