Overview

H-NBR in use

H-NBR is used in sealing technology when very good mechanical properties are required in combination with high temperatures. The material combines the advantages of NBR and EPDM.

As a universal all-round elastomer, H-NBR is used in the automotive industry for a wide variety of applications such as moulded articles, punched parts and O-rings.
