                            Zetpol? HNBR

                            Zetpol? hydrogenated nitrile (HNBR) is ZEON’s toughest, most durable elastomer. Zetpol resists prolonged exposure to 160°C and provides superior resistance to hot fluids. The toughness of Zetpol makes it the ideal choice for automotive belt, seals, and oil field components.

                            Zetpol is classified as a DH-DK polymer according to SAE J200 / ASTM D200.
