A Comprehensive Guide to Nitrile Rubber Products in China
China has emerged as a significant player in the global nitrile rubber (NBR) market. Numerous manufacturers produce a wide range of NBR products, catering to diverse industrial needs. This guide delves into the specifics of NBR in China, covering its technical features, different types, and market dynamics. Websites such as www.seal-china.com, www.tradewheel.com, and www.kaxite-rubber.com offer glimpses into the extensive product range available.
Understanding Nitrile Butadiene Rubber (NBR)
Nitrile rubber, also known as nitrile butadiene rubber (NBR), Buna-N, or acrylonitrile butadiene rubber, is a synthetic elastomer. It’s a copolymer of acrylonitrile and butadiene, offering a unique combination of properties. The ratio of these monomers determines the final characteristics of the NBR. Higher acrylonitrile content leads to improved oil and fuel resistance but reduces low-temperature flexibility. Polymerupdate.com provides detailed market analysis and pricing information on NBR.
Technical Features of NBR
The performance of NBR is heavily influenced by its acrylonitrile content and the addition of various fillers and additives during manufacturing. These additions modify properties like hardness, tensile strength, and temperature resistance. The following table highlights key technical features:
| Feature | Description |
|---|---|
| Acrylonitrile Content | Percentage of acrylonitrile in the polymer; impacts oil resistance and flexibility. |
| Hardness (Shore A) | Measures the rubber’s resistance to indentation; ranges from 40 to 90 Shore A. |
| Tensile Strength | Maximum stress the rubber can withstand before breaking; measured in MPa. |
| Elongation at Break | Percentage of elongation before breaking; indicates flexibility and elasticity. |
| Tear Strength | Resistance to tearing; measured in N/mm. |
| Temperature Resistance | Operating temperature range; varies depending on acrylonitrile content. |
| Oil Resistance | Resistance to various oils and fuels; increases with acrylonitrile content. |
| Chemical Resistance | Resistance to various chemicals; depends on specific formulation. |
Different Types of NBR Products
NBR is available in various forms, each suited for specific applications. The choice depends on the required properties and the intended use. Companies like those listed on www.rubber-tools.com showcase the breadth of NBR products available. Here’s a comparison of common types:
| Type | Form | Key Properties | Applications |
