A Comprehensive Guide to Nitrile Rubber in China
China has emerged as a significant player in the global nitrile rubber (NBR) market. From raw material suppliers to manufacturers of finished products, the country offers a diverse range of options for businesses seeking NBR solutions. This guide explores the world of Chinese NBR, covering its technical aspects, various types, and the key players involved.
Understanding Nitrile Rubber (NBR)
Nitrile rubber, also known as NBR, Buna-N, or acrylonitrile butadiene rubber, is a synthetic elastomer. It’s created by polymerizing acrylonitrile and butadiene monomers. This composition gives NBR its distinctive properties, making it highly suitable for a wide array of applications. Companies like Shandong Jieheng Energy Co., Ltd. (www.tradewheel.com) are prominent suppliers of this raw material.
Technical Features of Nitrile Rubber
The performance of NBR depends heavily on the ratio of acrylonitrile to butadiene. A higher acrylonitrile content generally leads to improved oil resistance but reduced flexibility. The following table highlights key technical features:
| Feature | Description |
|---|---|
| Acrylonitrile Content | Affects oil resistance and flexibility; higher content means better oil resistance. |
| Tensile Strength | Measures the material’s resistance to stretching before breaking. |
| Elongation | Indicates the maximum stretch before breaking, reflecting flexibility. |
| Hardness | Measured on the Shore A scale; higher values indicate harder rubber. |
| Oil Resistance | Resistance to various oils and fuels; a crucial property for many applications. |
| Temperature Resistance | Operational temperature range; varies depending on the specific formulation. |
| Abrasion Resistance | Resistance to wear and tear from friction. |
Types of Nitrile Rubber
NBR comes in various forms, each tailored for specific applications. The differences are primarily due to variations in acrylonitrile content, additives, and processing methods. Shida Rubber (www.shidarubber.com) offers a wide variety of NBR extrusions and profiles, showcasing the versatility of the material.
| Type | Acrylonitrile Content | Key Properties | Typical Applications |
|---|---|---|---|
| Low ACN NBR | Low | High flexibility, good low-temperature properties | Seals, gaskets, hoses requiring flexibility |
| Medium ACN NBR | Medium | Balance of oil resistance and flexibility | Automotive seals, O-rings, hydraulic components |
| High ACN NBR | High | Excellent oil resistance, good chemical resistance | Fuel system components, oil seals, demanding applications |
| Hydrogenated NBR (HNBR) | High, hydrogenated | Superior heat and chemical resistance, improved strength | High-temperature applications, demanding chemical exposure |
| NBR Latex | Emulsion form | Suitable for coating, dipping, and other processes | Specialized coatings, adhesives |
Key Players in China’s Nitrile Rubber Industry
Several companies play significant roles in China’s NBR industry. These include manufacturers specializing in various forms of NBR, such as sheets, rolls, and extruded profiles. These companies often offer customized solutions to meet diverse customer requirements. Kaxite Sealing (www.kaxite-rubber.com) is a prominent example, specializing in NBR rubber sheets. Tianjin-based manufacturers like ZXZ Rubber (www.zxzrubber.com) focus on rubber sheets and rolls. Polymerupdate (polymerupdate.com) provides detailed market analysis and pricing information, assisting businesses in making informed decisions.
Conclusion
China’s role in the global nitrile rubber market is undeniable. The country boasts a vast network of manufacturers, offering a wide selection of NBR products and custom solutions. Understanding the technical features and different types of NBR is crucial for selecting the appropriate material for specific applications. By leveraging the resources available, businesses can confidently source high-quality NBR from China.
