Comprehensive Insights into China’s NBR Market
China’s NBR market is a significant player in the global rubber industry. Numerous manufacturers cater to diverse needs, from large-scale production for industrial applications to specialized production for medical and automotive sectors. Companies like Ningbo Kaxite Sealing Materials Co., Ltd. (www.kaxite-rubber.com) and those listed on TradeWheel (www.tradewheel.com) represent the breadth of this market. The price fluctuations, as reported by Polymerupdate (polymerupdate.com), significantly impact the profitability and competitiveness of these companies. Understanding the market dynamics is crucial for both buyers and sellers.
Technical Features of NBR
NBR’s versatility stems from its chemical composition—a copolymer of acrylonitrile and butadiene. The ratio of these monomers determines the final properties. Higher acrylonitrile content increases oil resistance but reduces low-temperature flexibility. This balance is key to selecting the appropriate NBR grade for a specific application. Manufacturers like Kaxite (www.kaxite-rubber.com) offer a range of NBR grades to meet varied requirements. Websites like www.seal-china.com showcase the diverse applications of these technically advanced materials.
| Feature | Description |
|---|---|
| Acrylonitrile Content | Percentage of acrylonitrile in the copolymer; affects oil resistance and flexibility. |
| Tensile Strength | Measure of the material’s ability to withstand stretching before breaking. |
| Elongation at Break | Percentage increase in length before breaking; indicates flexibility. |
| Hardness | Measured on the Shore A scale; indicates the material’s resistance to indentation. |
| Oil Resistance | Resistance to swelling and degradation in the presence of various oils. |
| Temperature Range | Operational temperature limits; varies with acrylonitrile content. |
| Abrasion Resistance | Resistance to wear from friction. |
| Tear Strength | Resistance to tearing. |
Different Types of NBR
Beyond the acrylonitrile content, other factors influence NBR properties. These include the addition of fillers, plasticizers, and other additives to enhance specific performance characteristics. This results in various NBR types optimized for different applications. The detailed specifications for each type can be found on manufacturer websites like www.kaxite-rubber.com and supplier platforms such as www.tradewheel.com. The Rubber-Tools website (www.rubber-tools.com) offers a good comparison of various NBR grades.
| Type | Description | Key Properties | Applications |
|---|---|---|---|
| General Purpose NBR | Standard NBR with balanced properties. | Moderate oil resistance, good flexibility, average hardness. | Gaskets, seals, O-rings, hoses in less demanding environments. |
| High Nitrile NBR | Higher acrylonitrile content; excellent oil resistance. | High oil resistance, lower flexibility, higher hardness. | Seals, O-rings, hoses in applications with high oil exposure. |
| Low Temperature NBR | Modified to maintain flexibility at low temperatures. | Good low-temperature flexibility, moderate oil resistance. | Seals, O-rings, hoses in cold environments. |
| Hydrogenated NBR (HNBR) | Chemically modified for improved heat and chemical resistance. | Excellent heat resistance, high chemical resistance. | Seals, O-rings in high-temperature and chemical environments. |
| NBR Latex | Liquid form of NBR, used in dipping processes for gloves and coatings. | Easy processing, good film formation. | Medical gloves, coatings. |
