A Comprehensive Guide to Nitrile Butadiene Rubber (NBR) in China
Nitrile butadiene rubber (NBR), also known as Buna-N, is a versatile synthetic elastomer widely used in various applications. Its popularity stems from its excellent oil and fuel resistance, making it ideal for demanding industrial settings. This guide delves into the specifics of NBR in the significant Chinese market, exploring its properties, types, and market dynamics. Information is compiled from multiple market research firms including Grand View Research (www.grandviewresearch.com), Research and Markets (www.researchandmarkets.com), and Polymerupdate (polymerupdate.com), as well as MarketPublishers (marketpublishers.com).
Comprehensive Insights into NBR
NBR is a copolymer of acrylonitrile and butadiene. The ratio of these monomers determines the final properties of the rubber. A higher acrylonitrile content leads to increased oil resistance but reduces flexibility and low-temperature performance. Conversely, higher butadiene content results in better flexibility and cold resistance. This balance of properties makes NBR highly adaptable. Grand View Research projects significant growth for the Chinese NBR market, highlighting its importance in diverse sectors.
Technical Features of NBR
The specific properties of NBR vary depending on its composition and processing. However, several key features define its performance. These include excellent oil and fuel resistance, good abrasion resistance, and moderate tensile strength. Its chemical resistance is also a key advantage, making it suitable for contact with many solvents and chemicals. The data provided by Polymerupdate highlights the importance of accurate pricing information for this vital material.
| Feature | Description |
|---|---|
| Oil Resistance | Excellent; resists swelling and degradation in many oils and fuels. |
| Abrasion Resistance | Good; withstands wear and tear in various applications. |
| Tensile Strength | Moderate; balances strength and flexibility. |
| Chemical Resistance | Resistant to many solvents and chemicals, but not all. |
| Temperature Range | Varies depending on the grade; generally performs well in moderate temperatures. |
| Flexibility | Good, although this can be affected by the acrylonitrile content. |
Different Types of NBR
Several grades of NBR exist, each tailored to specific applications. These grades are primarily differentiated by their acrylonitrile content and the presence of additives. The reports from Research and Markets (www.researchandmarkets.com) detail specific market segments and their growth potential within China.
| Type | Acrylonitrile Content (%) | Properties | Applications |
