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.

Materials need to be resistant to oil, extreme heat, hydrogen sulfide, amine corrosion inhibitors, steam and explosive decompression. Zetpol meet these needs and is commonly used in a variety of oil & gas applications. Customers use Zetpol for blow out preventers, stators, water swellable packers, pipe protectors, drill bit seals, inflatable packers, well head seals, and down hole packers


Automotive Seals & O-Rings

It provides superior dynamic properties as well as minimum loss of hardness and modulus with increased temperature. These properties, coupled with Zetpol’s superior heat, oil, wear and ozone resistance, enable belts with higher operating temperatures and longer life. Zetpol is suitable for a variety of timing belts, including synchronous timing belts, V belts, and industrial belts.


Automotive Hoses
