SBR NBR NR Natural Rubber Compounds Custom 30 - 90 Shore A Hardness

Our SBR NBR NR Natural Rubber Compounds Custom 30 - 90 Shore A Hardness bring together three essential rubber materials—SBR (Styrene Butadiene Rubber), NBR (Nitrile Rubber), and NR (Natural Rubber)—each customizable in hardness from 30 to 90 Shore A. Unlike one-size-fits-all rubber compounds, our solutions allow you to select the exact hardness level, paired with the ideal rubber material, to match the specific demands of your application, ensuring optimal performance and long service life.

Every batch of our custom rubber compounds undergoes strict quality control, ensuring consistent hardness, uniform texture, and reliable performance. Whether you need soft, flexible compounds (30-50 Shore A) for shock absorption and sealing, medium-hard compounds (50-70 Shore A) for general industrial use, or hard, durable compounds (70-90 Shore A) for high-stress components, we tailor our formulations to your exact requirements, leveraging the unique properties of SBR, NBR, and NR.

• Custom 30-90 Shore A Hardness: Fully customizable hardness range (30 to 90 Shore A) to suit every application—from soft, malleable 30 Shore A for delicate sealing to rigid 90 Shore A for high-wear, high-stress components. Precision-calibrated hardness ensures consistent performance across every batch.
• Comprehensive Material Range: Offers SBR, NBR (Nitrile), and NR (Natural Rubber) compounds, each with targeted properties: • SBR Rubber Compounds: Excellent abrasion resistance, good flexibility, and cost-effectiveness; ideal for general industrial parts, tires, and gaskets. • NBR Nitrile Rubber Compounds: Superior oil, fuel, and grease resistance; perfect for automotive seals, hydraulic components, and oil-contact applications. • NR Natural Rubber Compounds: Exceptional elasticity, tensile strength, and tear resistance; suitable for shock absorbers, conveyor belts, and high-flex applications.

Our custom hardness rubber compounds have a precision tolerance of ±2 Shore A. We use advanced Shore A hardness testers during production and quality inspection to ensure each batch meets your exact hardness requirement, with no variations across the product.

You can choose any hardness level between 30-90 Shore A, with customization available in 5 Shore A increments (e.g., 30, 35, 40... 90). For special requirements, we can also provide custom increments (±1 Shore A) for critical applications—just let our technical team know your needs.

The right material depends on your application: SBR is ideal for general industrial use (cost-effective, abrasion-resistant); NBR for oil/fuel contact applications; NR for high elasticity and tear resistance. For hardness: 30-50 Shore A (soft) for seals/shock absorption; 50-70 Shore A (medium) for general parts; 70-90 Shore A (hard) for high-stress/wear components. Our team can help you select the perfect combination.

Yes. All our SBR, NBR, and NR custom hardness compounds are compatible with standard rubber processing methods, including compression molding, injection molding, extrusion, die-cutting, and punching. The uniform hardness and texture ensure seamless production of custom parts with no additional adjustments.

Shelf life varies slightly by material: SBR and NBR compounds have a shelf life of 12-18 months, while NR natural rubber compounds have a shelf life of 10-16 months—when stored in a cool, dry, dark environment (away from direct sunlight, ozone, and high temperatures). After shelf life, the material can still be used if it passes our quality and hardness inspection.

Yes. Our technical team can create custom hybrid blends of SBR, NBR, and NR to combine their unique properties (e.g., SBR’s abrasion resistance + NBR’s oil resistance) with your desired hardness (30-90 Shore A). We work with you to design a blend that meets your specific application requirements.
