Engineered for Excellence
NBR Nitrile Rubber That Delivers
At GB Gummi, we specialize in providing durable, versatile, and high-quality rubber solutions for industrial and commercial needs. One of our flagship materials is Nitrile Butadiene Rubber (NBR), a synthetic rubber known for its exceptional resistance to oil, fuel, and chemicals. Commonly referred to as nitrile rubber or NBR rubber, this material is engineered to meet the highest standards across multiple industries, from automotive to oil & gas.
With a reputation for combining flexibility, resilience, and sealing capabilities, nitrile rubber is the material of choice when oil resistance and wear strength are critical. Whether it’s seals, gaskets, or hoses, our NBR rubber delivers uncompromising performance in even the hardest environments.
Properties of Nitrile Butadiene Rubber
Nitrile Butadiene Rubber is a copolymer of butadiene and acrylonitrile, and its performance properties can be fine-tuned depending on the acrylonitrile content. The higher the acrylonitrile content, the better the oil resistance, but with a trade-off in flexibility.
Key properties include:
What are the Different Types of Nitrile Rubber?
General-Purpose NBR (Nitrile Butadiene Rubber)
This is the most widely used type of nitrile rubber, ideal for general sealing and gasketing needs. NBR nitrile in this form offers moderate resistance to oils, fuels, and chemicals, making it suitable for non-extreme environments. Its excellent flexibility, tensile strength, and cost-effectiveness make it a preferred material for O-rings, gaskets, and hoses across various industries.
Carboxylated NBR (XNBR)
A toughened version of standard NBR rubber, XNBR incorporates carboxylic acid groups into the polymer chain. This modification significantly boosts abrasion resistance, tensile strength, and tear resistance—while maintaining oil resistance. XNBR is commonly used in high-performance applications like dynamic seals, conveyor belts, and parts exposed to mechanical stress.
Hydrogenated NBR (HNBR)
HNBR is a chemically enhanced form of nitrile butadiene rubber, created through hydrogenation to reduce double bonds in the structure. This improves heat resistance, ozone stability, and aging performance. HNBR retains the oil and fuel compatibility of traditional, making it suitable for critical automotive parts (timing belts, hoses) as well as aerospace and industrial systems facing extreme conditions.
PVC/NBR Blends (Polyvinyl Chloride and Nitrile Rubber)
These blends with PVC to enhance flame resistance, chemical durability, and weather tolerance. The synergy of both materials results in versatile compounds used in fuel hoses, cable insulation, seals, and coatings, where fire safety and chemical strength are equally important.
Advantages & Benefits of NBR Nitrile
- Used widely in the automotive, oil & gas, and manufacturing sectors, NBR nitrile (or nitrile butadiene rubber) stands out due to its well-balanced performance properties. Here’s what makes it an ideal material for demanding environments:
- Superior oil and fuel resistance
- Good mechanical strength and flexibility
- Excellent wear and tear resistance
- Resistant to a wide range of chemicals
- Customizable for hardness, density, and temperature performance
- Cost-effective alternative to more expensive elastomers
- Performs well in dynamic and static sealing conditions
Applications of NBR Rubber
- NBR rubber is a versatile elastomer trusted across multiple industries for its outstanding oil resistance, mechanical strength, and temperature tolerance. From automotive engines to industrial machinery and even everyday consumer products, nitrile rubber plays a critical role in ensuring durability, safety, and performance under demanding conditions.
- Its adaptability to different formulations and environments makes it a go-to material in both static and dynamic applications.
- Automotive industry – fuel lines, gaskets, seals, and O-rings
- Oil and gas – hoses, blowout preventers, and pipeline seals
- Chemical plants – protective gloves, gaskets, and tubing
- Agriculture – hydraulic hoses and fuel system components
- Industrial manufacturing – rollers, conveyor belts, and diaphragms
- Personal protective equipment – chemical-resistant gloves
What is Nitrile Rubber Used For?
NBR is widely used in industries that require durable, oil-resistant materials. It is commonly found in:
Sealing applications
O-rings, gaskets, and washers

What Makes Nitrile Rubber (NBR) Unique?
- What sets NBR apart is its superior compatibility with oils and fuels, which natural rubber lacks. Its structure allows for chemical bonding with hydrocarbons, providing unmatched resistance in fluid transfer applications. Moreover, it offers a balance between performance and affordability, making it ideal for both OEMs and aftermarket solutions.
Why use Nitrile Rubber?
- Industries choose nitrile rubber not just for its chemical resistance, but for its proven reliability in the field. Whether it's heavy-duty machinery or complex fluid systems, NBR rubber delivers consistent performance over time—reducing downtime, enhancing operational efficiency, and aligning with modern sustainability goals.
- Long-lasting performance in challenging environments
- Lower maintenance costs due to its durability
- Reliable sealing and mechanical support
- Compatibility with existing systems and manufacturing processes
- An eco-conscious and sustainable solution with recyclable options
