In industrial production, rollers are an essential component for conveying, supporting and handling materials. Among them, Nitrile Rubber Roller is widely used in many industries due to its excellent oil resistance and wear resistance.

This article will explore the composition, characteristics, application areas and performance of Nitrile Rubber Roller under different working conditions to help readers fully understand this important industrial component.

What is Nitrile Rubber (NBR)?

Nitrile Rubber (NBR) is a synthetic rubber copolymerized by acrylonitrile (ACN) and butadiene (BD) monomers. According to the acrylonitrile content, NBR can be divided into the following categories:

1. High acrylonitrile content (42~46%): has excellent oil resistance, but low cold resistance.

2. Medium-high acrylonitrile content (36~41%): a good balance between oil resistance and cold resistance.

3. Medium acrylonitrile content (31~35%): moderate oil resistance and cold resistance.

4. Medium to low acrylonitrile content (25~30%): good cold resistance, suitable for low temperature environment.

5. Low acrylonitrile content (18~24%): excellent cold resistance, but poor oil resistance.

What are the characteristics of nitrile rubber?

Nitrile rubber has: excellent oil resistance, good wear resistance, heat resistance, good elasticity and strength and other significant characteristics.

1. Excellent oil resistance: especially suitable for environments in contact with mineral oil, vegetable oil and some fuel oil.

2. Good wear resistance: suitable for high wear conditions and extend the service life of the roller.

3. Heat resistance: can be used for a long time in air at 120°C or oil at 150°C, suitable for high temperature conditions.

4. Good elasticity and strength: with good elasticity and mechanical strength, it can maintain stable performance in high pressure environment.
