A Comprehensive Guide to Nitrile Rubber Suppliers in China
China has emerged as a significant global hub for nitrile rubber production and supply. Numerous companies, such as those listed on www.tradewheel.com, offer a wide range of nitrile rubber products, catering to diverse industrial needs. This guide delves into the intricacies of nitrile rubber, its technical features, various types, and key considerations when sourcing from Chinese suppliers. Understanding these aspects is crucial for businesses seeking high-quality, cost-effective nitrile rubber solutions.
Understanding Nitrile Rubber (NBR)
Nitrile rubber, also known as Buna-N, Perbunan, or acrylonitrile butadiene rubber (NBR), is a synthetic elastomer. It is created through the copolymerization of butadiene and acrylonitrile. The ratio of these monomers directly influences the final properties of the rubber. Companies like www.kaxite-rubber.com specialize in providing various grades of NBR. Its primary advantage lies in its excellent resistance to oils, fuels, and various chemicals. This makes it suitable for applications requiring durability in harsh environments. The oil resistance is directly proportional to the acrylonitrile content.
Technical Features of Nitrile Rubber
The following table compares the key technical features of nitrile rubber:
| Feature | Description | Units |
|---|---|---|
| Tensile Strength | The maximum stress a material can withstand before breaking. | MPa |
| Elongation at Break | The extent to which a material can stretch before breaking. | % |
| Hardness | Resistance to indentation, measured using a durometer. | Shore A |
| Tear Strength | Resistance to tearing. | N/mm |
| Abrasion Resistance | Resistance to wear and tear from friction. | mm³/Nm |
| Compression Set | The ability to retain its shape after compression. | % |
| Temperature Range | The range of temperatures at which the rubber maintains its properties. | °C |
| Oil Resistance | Resistance to swelling and degradation in the presence of oils and fuels. | Varies |
| Chemical Resistance | Resistance to degradation by various chemicals. | Varies |
Types of Nitrile Rubber
Nitrile rubber comes in various forms, each with distinct properties. The choice depends on the specific application. Here’s a comparison table outlining different types:
| Type | Acrylonitrile Content | Key Properties | Applications |
|---|---|---|---|
| Low Acrylonitrile | Low | High flexibility, good low-temperature resistance | Seals, gaskets for low-temperature applications |
| Medium Acrylonitrile | Medium | Balanced properties, good oil and chemical resistance | General-purpose seals, hoses, O-rings |
| High Acrylonitrile | High | Excellent oil and chemical resistance, high strength | Oil seals, fuel system components, specialized gaskets |
| HNBR (Hydrogenated) | Fully hydrogenated | Superior heat, ozone, and chemical resistance | High-temperature applications, demanding environments |
Suppliers such as www.seal-china.com offer a wide selection of these NBR types. www.zxzrubber.com also provides various grades of nitrile rubber sheets and rolls, highlighting their manufacturing capabilities. Hairui Rubber (www.hairuirubber.com) further diversifies its offerings by including nitrile rubber in its insulation product lines.
Sourcing Nitrile Rubber from China
When sourcing nitrile rubber from China, several factors are crucial. These include verifying the supplier’s certifications (ISO 9001, etc.), examining their manufacturing capabilities, and clearly specifying the required technical properties. Price is a key factor, but should not compromise quality. Thorough due diligence, including sample testing and verifying production capacity, helps mitigate risks. TradeWheel (www.tradewheel.com) provides a platform to connect with numerous Chinese suppliers, allowing for comparison and selection.
Conclusion
China’s nitrile rubber industry offers a diverse range of products and suppliers. Understanding the technical aspects, different types, and sourcing considerations is essential for businesses to make informed decisions. By conducting thorough due diligence and selecting a reputable supplier, businesses can secure high-quality nitrile rubber at competitive prices.
FAQs
1. What are the key advantages of using nitrile rubber?
Nitrile rubber’s main advantages are its exceptional oil and chemical resistance, making it ideal for applications involving exposure to oils, fuels, and various chemicals. It also possesses good mechanical properties, including tensile strength and abrasion resistance.
2. How does acrylonitrile content affect nitrile rubber properties?
Higher acrylonitrile content leads to increased oil and chemical resistance but reduces flexibility and low-temperature performance. Lower acrylonitrile content enhances flexibility and low-temperature performance but compromises oil resistance.
3. What are some common applications of nitrile rubber?
Nitrile rubber finds widespread use in seals, gaskets, O-rings, hoses, and other components requiring oil and chemical resistance. Applications span various industries, including automotive, aerospace, and industrial manufacturing.
4. What factors should I consider when choosing a nitrile rubber supplier in China?
Consider the supplier’s certifications, manufacturing capabilities, quality control measures, and their ability to meet specific technical requirements. It’s also vital to assess their reliability and communication effectiveness.
5. How can I ensure the quality of nitrile rubber sourced from China?
