Industrial elastomers by Daemar work well in extremely low temperatures

HNBR elastomers suit challenging environments.

Daemar Inc. is renowned for its unmatched supply of essential components for industry, including a broad variety of sealing units. The distributor offers many kinds of O-rings, and one series that stands out for severe work conditions is a line of Hydrogenated Acrylonitrile Butadiene industrial elastomers, or HNBR elastomers.

These are black O-rings that come in a full line of durometer – specifically, 70, 80, and 90-durometer – to work for various applications in different sectors. HNBR elastomers offer unusually long service life to users.

Resists sour gasoline and ozone

HNBR is also known as HSN, which stands for Highly Saturated Nitrile. This material is superior to nitrile rubber, or NBR, when it comes to resistance to low brittle temperatures, heat, oil, oil additives, and sour oil. In addition, HNBR is far more resistant than NBR is to sour gasoline and ozone, and this makes it ideal for improving components that would normally be made from NBR. This enables their use in severe work conditions.

These industrial elastomers provide an unsurpassed spectrum of performance at a cost between NBR and (per)fluoroelastomers. HNBR components serve to fill the gap between these two elements in plenty of tasks that need resistance to both heat and aggressive media at the same time. The Daemar team highly recommends HNBR elastomers in applications that require strong resistance to ozone and weathering, industrial lubricants, amine-based corrosion inhibitors, sour gases such as hydrogen sulfide, hot water, or steam. These components are especially popular in the oil and gas sector; workers in this field use them for applications involving O-rings, hammer union seals, and gaskets.

Other benefits of using HNBR industrial elastomers: high media resistance; high heat and oxidation stability; high mechanical strength; better wear resistance; suitability in ultra-pure water and steam; and typical hardness range from 70 to 90 Shore A. These units are perfect for cold-weather work environments, with a standard temperature range from -50 to 160 degrees Celsius. Daemar has temperature-rated its 80-durometer O-rings to -50 degrees Celsius to keep pace with the increasing demand for HNBR in cold weather.
