Nitrile Butadiene Rubber (NBR) – The Ideal Synthetic Rubber for Oil & Chemical Resistance

SYNTHETIC RUBBER PRODUCT offers high-quality Nitrile Butadiene Rubber (NBR)—a top-performing synthetic rubber trusted across automotive, oil & gas, power generation, and engineering industries.

Known for its outstanding resistance to oil, chemicals, heat, and wear, NBR is the go-to choice for a wide range of industrial sealing and gasketing applications.

 

What Is Nitrile Butadiene Rubber (NBR)?

NBR is a synthetic rubber made from a blend of acrylonitrile and butadiene. It’s specifically engineered to resist degradation from:

• Petroleum-based oils
• Fuels and greases
• Solvents, acids, and alkalis
• Heat and oxidative aging

Its excellent mechanical strength and flexibility make it ideal for demanding environments with exposure to fluids and fluctuating temperatures.

 

Key Benefits of NBR Rubber

• ✅ Excellent oil and fuel resistance
• ✅ High mechanical strength and tear resistance
• ✅ Good thermal stability
• ✅ Effective in chemical-rich environments
• ✅ Low gas permeability
• ✅ Abrasion and impact resistant
• ✅ Long-lasting weather and ozone resistance
