Rubber, a ubiquitous material with diverse applications, plays a pivotal role in various industries. Among the different types of rubber, nitrile rubber stands out for its unique properties and versatility. Also known as NBR (acrylonitrile-butadiene rubber), nitrile rubber has gained prominence in industrial applications due to its excellent resistance to oil, fuel, and other chemicals. In this blog post, we will delve into the fascinating world of nitrile rubber, exploring its composition, properties, and wide-ranging applications.
Composition
Nitrile rubber is a synthetic copolymer composed of two principal monomers: acrylonitrile and butadiene. The percentage of these monomers in the polymer determines the specific characteristics of the resulting nitrile rubber. Generally, a higher acrylonitrile content enhances oil and chemical resistance, while a higher butadiene content contributes to improved flexibility and low-temperature performance.
