APPLICATIONS
Oil & Gas
Deeper, hotter wells require tough elastomers. 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
Zetpol HNBR maintains excellent physical properties, including in mixed environments of oil + water/coolant. It is ideal for various sealing applications: Zetpol can be used on front cover, intake manifold, and oil pan gaskets, as well as drain plug seals and water pump seals.
Timing Belts
Zetpol is ideally suited to meet the requirements of belting applications. 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
Zetpol’s excellent heat and fluid resistance allows for extended service life at elevated temperatures. Zetpol has good resistance to biodiesel and is well suited for use in bio-diesel hose, industrial hose, and hydraulic hose.
Rolls
High hardness Zetpol rolls offer excellent physical properties and are designed to provide rolls with higher operating speeds and longer service-life. Its dynamic properties make it an ideal material for large rolls used in paper mills and industrial settings, including couch rolls, pickup rolls, and sizing rolls.
