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.


Advantages:

- Notable overall resistance to solvents and lubricants

- Commendable resistance to oils and petrol

- Demonstrates good compression set and tear strength

- Operates well over a wide temperature range

- Displays strong resistance to alkalis and acids

- Exhibits good tensile strength and flexibility

- Displays moderate aging properties

- Establishes reliable adhesion to metal surfaces

- Performs effectively with water exposure

- Features solid recovery properties


Applications:

- Widely used in industries involving inorganic chemical products

- Unsuitable for applications involving antioxidant agents and chlorine

- Well-suited for petroleum-based hydraulic fluids and oils

- Valuable in general hydrocarbon applications

- Highly suitable material for gaskets

- Essential in industrial maintenance operations

- Ideal for rubber seal strips and more.
