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.
