Technical Features of NBR
NBR is a copolymer of acrylonitrile (ACN) and butadiene. The ratio of these monomers significantly influences the final properties of the rubber. Higher ACN content generally leads to increased oil resistance but reduced flexibility. The temperature range for NBR applications typically spans from -40°C to +125°C, depending on the ACN content. The manufacturing process typically involves emulsion polymerization, coagulation, and drying. Detailed technical specifications are often available from suppliers like those listed on Rubber-Tools.com.
| Feature | Description |
|---|---|
| Monomers | Acrylonitrile and butadiene |
| ACN Content (%) | Varies from 18% to 50%, impacting oil resistance and flexibility |
| Tensile Strength | High |
| Abrasion Resistance | High |
| Oil Resistance | Excellent, highly dependent on ACN content |
| Temperature Range | -40°C to +125°C (depending on ACN content) |
| Chemical Resistance | Good resistance to many chemicals, but varies depending on specific chemical and ACN content |
| Gas Permeability | Low |
Different Types of NBR
NBR is available in various forms and grades, tailored to meet diverse application requirements. The key differentiators include ACN content, molecular weight, and additives. Intratec provides detailed information on NBR pricing and market trends, including various grades and their respective properties.
| Type | Description | Key Properties | Applications |
|---|---|---|---|
| Standard NBR | General-purpose NBR with moderate oil resistance and flexibility | Balance of oil resistance and flexibility | Seals, gaskets, hoses |
| High Nitrile NBR | Higher ACN content, offering superior oil and chemical resistance, but lower flexibility | Excellent oil and chemical resistance, good heat resistance | Oil seals, fuel lines, chemical handling equipment |
| Low Nitrile NBR | Lower ACN content, providing greater flexibility and low-temperature performance | High flexibility, good low-temperature performance | Gloves, general-purpose rubber goods |
| Specialty NBR | Modified NBR with specific additives to enhance certain properties (e.g., heat resistance, flame retardancy) | Enhanced properties depending on additives (e.g., heat resistance, flame retardancy) | High-temperature applications, fire-resistant components |
| NBR Latex | NBR in liquid form, used for dipping and coating processes | Easy processing, suitable for various coating applications | Gloves, coatings |
