2025-08-29
When it comes to industrial applications requiring durability, flexibility, and resistance to oils and chemicals, NBR Rubber Compound stands out as a top choice. With over two decades of expertise in polymer science, we provide an in-depth look at the key physical properties that make this material indispensable across various sectors. Whether you're in automotive manufacturing, oil and gas, or consumer goods, understanding these parameters ensures optimal performance and longevity for your products.
Key Physical Properties of NBR Rubber Compound
NBR (Nitrile Butadiene Rubber) is renowned for its excellent balance of strength and resilience. Below, we break down its critical properties using detailed lists and tables for clarity and precision.
Primary Characteristics:
-
Oil and Fuel Resistance: Highly resistant to oils, fuels, and solvents, making it ideal for seals, gaskets, and hoses.
-
Temperature Tolerance: Performs reliably in temperatures ranging from -40°C to 120°C (-40°F to 248°F).
-
Abrasion Resistance: Exhibits superior wear resistance, suitable for dynamic applications like rollers and belts.
-
Tensile Strength: Offers robust mechanical strength, ensuring durability under stress.
-
Flexibility: Maintains elasticity even in low-temperature environments.
Detailed Property Table:
| Property Type | Test Method | Value Range | Units |
|---|---|---|---|
| Hardness | ASTM D2240 | 40 - 90 | Shore A |
| Tensile Strength | ASTM D412 | 17 - 25 | MPa |
| Elongation at Break | ASTM D412 | 300 - 600 | % |
| Compression Set | ASTM D395 | 20 - 40 | % |
| Specific Gravity | ASTM D792 | 1.00 - 1.20 | g/cm³ |
| Tear Resistance | ASTM D624 | 30 - 50 | kN/m |
Why Choose NBR Rubber Compound?
The versatility of NBR Rubber Compound stems from its nitrile content, which directly influences its resistance properties. Higher nitrile levels enhance oil and fuel resistance but may reduce flexibility at lower temperatures. This compound is also compatible with additives to improve heat resistance or meet specific regulatory standards, such as FDA compliance for food-grade applications.
Applications and Benefits
From automotive engine parts to industrial machinery components, the NBR Rubber Compound excels in environments exposed to harsh fluids and mechanical stress. Its cost-effectiveness and reliability make it a preferred material for O-rings, diaphragms, and custom-molded products.
In summary, the physical properties of NBR Rubber Compound make it a cornerstone material for industries demanding high performance and resilience. By leveraging these attributes, manufacturers can achieve greater product efficiency and customer satisfaction.
