NBR vs Nitrile: Understanding the Key Differences

## NBR vs Nitrile: Understanding the Key Differences.

1. What is NBR?

2. What is Nitrile?

3. What are the key differences between NBR and Nitrile?

### 1. What is NBR?

NBR, or nitrile butadiene rubber, is a type of synthetic rubber that is primarily used in industrial applications for its excellent oil resistance and durability. It is commonly used in seals, gaskets, O-rings, and hoses, where resistance to oil, fuel, and other chemicals is required.

### 2. What is Nitrile?

Nitrile, on the other hand, is a type of synthetic rubber that is known for its excellent resistance to oil, fuel, and other chemicals. It is commonly used in gloves, seals, gaskets, and O-rings, where protection against chemicals is essential. Nitrile is also known for its flexibility and durability.

### 3. What are the key differences between NBR and Nitrile?

The key difference between NBR and Nitrile lies in their chemical composition. NBR is a copolymer of butadiene and acrylonitrile, while Nitrile is a copolymer of butadiene and cyanoethene. This difference in composition results in slightly different properties between the two materials.

NBR generally has higher resistance to temperature, abrasion, and tear, making it ideal for applications where these properties are crucial. On the other hand, Nitrile has better resistance to oils, fuels, and chemicals, making it a preferred choice for applications requiring such properties.

In summary, while both NBR and Nitrile are synthetic rubbers with excellent resistance to various chemicals, they have slight differences in their properties due to their chemical composition. It is essential to consider these differences when choosing between NBR and Nitrile for specific applications.
