Yozonetech provides a comprehensive selection of NBR Rubber Oring. Catering to diverse requirements, we offer a wide range of rubber Oring materials. Our production is tailored to meet customer demands, encompassing various rubber products, including manufacturer gaskets, and cloth or wire reinforced rubber Orings.

Nitrile Rubber, also known as Butadiene Acrylonitrile, Buna-N, Perbunan, or NBR rubber, originated in 1941 during a project aimed at developing an oil-resistant rubber. The resistance of NBR to oil and fuel is contingent upon the acrylonitrile grade used.

A higher acrylonitrile grade corresponds to enhanced oil and fuel resistance. However, increased acrylonitrile content leads to reduced tolerance for low temperatures. While NBR exhibits commendable abrasion resistance, its physical properties are moderately rated compared to Natural Rubber.

Nitrile rubber Orings excel in resisting oils, petrol, solvents, and lubricants, yet they display weak ozone resistance. Moreover, NBR boasts solid resistance against inorganic chemicals except antioxidant agents and chlorine, maintaining satisfactory resilience against general hydrocarbons.
