Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-40°F to +257°F) or (-4.44°C to +125°C) and one of the best performance-to-cost values. It's an ideal material for aerospace, automotive, propane and natural gas applications.
Fluorocarbon FKM exhibits exceptional resistance to chemicals, oils, temperature extremes (-13°F to +446°F) or (-10.56°C to +230°C) , low compression set, low gas permeability and excellent aging characteristics. Applications include: aircraft engines, automotive fuel handling systems, and chemical processing industries. FKM is also suitable for high vacuum applications. It is not recommended for exposure to ketones, alkalis, and Skydrol® fluids. Custom compounds are available with improve
Neoprene (-40º to +250ºF) or (-4.44°C to +121°C) is reasonably priced and features good resistance to petroleum oils, ozone, sunlight and oxygen aging, relatively low compression set, good resilience and outstanding physical toughness. It is the preferred sealing material for the refrigeration industry because of its resistance to ammonia and Freon®.
Standard compounds handle operating temperatures -85ºF to +400ºF. (-29.44°C to +204°C) Silicone compounds are popular in food and medical applications because they are very clean and do not impart odor or taste. Special Phenyl silicones can be used down to -148°F.
It ’s excellent lubricity , chemical and Temperature resistant is -300 degree F up to 500 degree F. or (-148.89°C to +260°C) Because of cold flow and high mechanical seal strength , Teflon does not seal well unless very carefully designed.
Encapsulate O-rings are o-rings consisting of a seamless and uniform Teflon® FEP/PFA encapsulation/jacket which completely encloses a core material of either silicone or Viton® elastomers. The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments. The temperature resistant is -75 degree F up to 400 degree F or (-23.89°C to +204.44°C)
Material : Kalrez® O-Rings Kalrez® o-rings and seals are available in a number of different compounds that are formulated to optimize properties and give the best possible performance in various chemicals and temperatures. Modification of the finished properties is achieved by use of fillers and other additives to enhance their performance. When using Kalrez® o-rings and seals it is important to consider all factors such as process chemicals, process temperatures and seal design. Before consid
EPDM rubber has an exceptionally good ability to reverse deformation under the influence of mechanical forces. The deformation is created while maintaining the structure of the continuity of the material. This property does not change, even in the face of temperatures up to +110 degrees. EPDM rubber remains flexible even in a collision with a temperature of 40 degrees below zero. (Temperature range: -40°C to +110° C)
