Daemar’s tips on choosing an elastomer for an operating environment

Elastomers of various materials are available.

The performance of a seal in a specific operating environment depends highly on the elastomer, which must suit the operating conditions. As a major supplier of essential industrial components, Daemar Inc. knows that production may subject elastomeric components to multiple factors. Such conditions can include resistance to Ozone, weather, chemicals, oil, or cold temperatures. For effective performance and longevity from these components, a business must pick an elastomer that best suits the particular conditions of the environment.

Ample Daemar resources available

The Daemar website includes ample resources to help customers make the correct elastomer selection. Examples of these resources: a chart specifying comparison of different elastomer properties; a list of elastomers with their general properties; information on their temperature ranges and durometer numbers; a fluid-compatibility selector; and a general guide to storage and shelf life.

The supplier carries a line of elastomers that have been approved by the United States Food and Drug Administration (FDA). These units are designed and engineered to perform in harsh medical and pharmaceutical processing environments and withstand the regular cycles and chemicals of equipment wash-down. The Daemar team offers FDA-approved elastomers and urethane sealing components for FDA-approved medical and sanitary supplies; these components are common in equipment in challenging sanitary environments.

For industrial processes conducted in cold weather, the customer requires an elastomer that performs in low temperatures. Daemar has units made of Hydrogenated Acrylonitrile Butadiene, which is superior to NBR in low brittle temperatures and lasts longer; these elastomers can handle temperatures as low as -45 degrees Celsius.

For aggressive chemical processing, temperatures as high as 327 degrees Celsius, and other extreme operating environments, Daemar offers Kalrez components from DuPont. These elastomers are engineered specially for these challenging conditions, and using Kalrez can result in cost savings due to lower cost of ownership, longer lifespans, and less maintenance. Kalrez seals also comply with the highest safety standards in such sectors as pharmaceuticals, medical packaging, and food processing.

Daemar carries elastomers made of NBR, silicone, fluorocarbon, chloroprene, ethylene propylene, styrene butadiene, fluorosilicone, polyurethane, and other materials, to suit different applications.
