The functional rubber material e-NBR, which is being jointly developed by 922 Research Institute and Miyasaka Rubber, continues garnering attention. The material has a tensile strength of 20.0 MPa, equivalent to that of hydrogenated nitrile rubber (H-NBR), but is less expensive than H-NBR. It also has ozone resistance equivalent to 100 years (theoretical value) and does not require plasticizers, fillers,…
