The manufacturing of NBR and SBR is similar, Manufactured by emulsion polymerization, emulsifiers, polymerizers, etc. are also roughly the same system as SBR. Because NBR has good oil resistance and chemical resistance, it is widely used in industrial products, such as O-rings, compression, oil seals, etc.<\/li>\n<li>Characteristics: The biggest characteristic of NBR lies in its oil resistance, which depends on its composition, molecular structure and polymerization conditions. Polarity. That is, the higher the acrylic content, the better the oil resistance of the NBR. In addition to the oil resistance, the amount of sunlight bound in the NBR also greatly affects the physical properties of the sulfur compound.
