Custom HNBR Extrusions and Profiles

At Kismet Rubber Products, we leverage highly trained personnel and innovative extrusion equipment to produce high-performing custom HNBR gaskets and seals. Hydrogenated nitrile butadiene rubber is a highly saturated elastomer engineered for demanding environments. We provide a wide selection of extruded rubber materials and serve the OEM and replacement part markets with reliable components tailored to your exact industry requirements.

High-Performance Hydrogenated Nitrile for Severe Environments

Standard nitrile rubber offers excellent oil resistance but often degrades when exposed to extreme heat or prolonged weathering. The hydrogenation process modifies the polymer chain to solve these issues, creating an incredibly resilient extrusion. This specialized chemistry allows HNBR profiles to maintain their physical toughness and mechanical strength when exposed to modern synthetic oils and aggressive fuels, as well as chemical coolants. Furthermore, HNBR provides a continuous operating temperature range from negative 60 degrees to 160 degrees Celsius, making it highly dependable for severe duty cycles.

FAQs

How does extruded HNBR compare to standard nitrile?

While standard nitrile provides strong resistance to petroleum, it is vulnerable to ozone degradation and high heat. Hydrogenated nitrile fixes these weaknesses, offering far superior mechanical strength and enhanced wear resistance, along with the ability to survive extreme thermal environments without becoming brittle.

Can you extrude HNBR into complex profiles?

Yes. Our facility is equipped with advanced extrusion lines that allow us to manufacture highly complex geometries. We can produce custom sealing strips and multi-lumen tubing, as well as specialized door gaskets tailored to fit the exact dimensions of your hardware.

What information is needed to quote an HNBR extrusion project?

To provide an accurate quote, our team requires the expected production volume and a basic drawing of the desired profile. Supplying details about the operating environment, including temperature ranges and specific chemical exposures, ensures we select the optimal elastomer formulation for your project.
