Comprehensive Guide to NBR and SBR Rubber in China
Nitrile Butadiene Rubber (NBR) and Styrene Butadiene Rubber (SBR) are two of the most widely used synthetic rubbers in various industries. They are known for their excellent mechanical properties, durability, and resistance to oils and chemicals. This guide will delve into the characteristics, applications, and differences between NBR and SBR rubber, focusing on manufacturers in China, including Kaxite Rubber, Hebei No.6 Rubber Co., and others.
Understanding NBR and SBR Rubber
NBR is a copolymer of acrylonitrile and butadiene, making it highly resistant to oils, fuels, and other chemicals. It is commonly used in automotive applications, gaskets, seals, and hoses. On the other hand, SBR is a copolymer of styrene and butadiene, known for its excellent abrasion resistance and aging stability. It is primarily used in tires, conveyor belts, and various industrial applications.
