NBR and SBR
NBR (Nitrile Butadiene Rubber) and SBR (Styrene Butadiene Rubber) are two of the most widely used synthetic rubbers in the rubber and manufacturing industry. Known for their reliability, durability, and versatile performance, these rubbers form the backbone of industrial compounding and product manufacturing.
NBR is valued for its excellent resistance to oils, fuels, chemicals, and abrasion, making it essential for automotive parts, hoses, seals, gaskets, and industrial rubber goods. Its ability to withstand harsh environments makes it a preferred choice for engineering applications.
SBR, on the other hand, offers strong wear resistance, flexibility, and good tensile properties. It is commonly used in tyres, conveyor belts, footwear, foam products, and general-purpose rubber items. SBR provides consistent performance across a wide range of processing and molding applications.

Benefits
Benefits of NBR (Nitrile Butadiene Rubber) NBR is widely used across automotive, industrial, and mechanical applications due to its exceptional resistance to oils, fuels, and chemicals. This makes it ideal for environments where exposure to petroleum-based substances is unavoidable. It offers high tensile strength and superior abrasion resistance, allowing products like gaskets, seals, hoses, and O-rings to withstand continuous wear without degrading. NBR also maintains its performance under varying temperature conditions, making it suitable for both high-heat and moderately low-temperature applications. Its reliable sealing capability reduces the risk of leakage and equipment failure, improving operational safety and efficiency. Benefits of SBR (Styrene Butadiene Rubber) SBR is one of the most commonly used synthetic rubbers due to its excellent balance of flexibility, durability, and cost-effectiveness. Its strong abrasion resistance makes it suitable for tyres, conveyor belts, footwear soles, and high-wear industrial products. SBR offers good elasticity and stable mechanical properties, ensuring consistent performance across different processing methods such as molding, extrusion, and compounding. It blends easily with fillers and additives, making it a highly adaptable material for diverse manufacturing needs. Additionally, SBR’s affordability makes it a preferred choice for large-scale production where performance and cost must be balanced.
