We also manufacture using various grades of elastomers, custom blending of any of the polymers to handle varying amounts of temperature change with spring candidates ranging from a simple Buna-n O-ring to a sophisticated spring energized seal. Lets start out with the most basic material, NBR or Buna-n rubber. 0000001118 00000 n *$( %2%(,-/0/#484.7*./. C Silicones with FAR 25.853 include HT-800 which is stocked as a foam and a solid, in sheet and strip form. Some flexible rubbers can function in continuous temperatures of up to+300Csuch as a high temperaturesilicone, however higher temperatures will requireceramic,micaandclaybased materials that can be used between+500Cand+1200C. However, nitrile provides poor ozone, sunlight, and weather resistance, therefore it is not recommended for outside applications. Application Temperature: For best results the temperature of the adhesive and surfaces to be bonded should be at least 65F (18C). Catastrophic failure of a gasket or pad can also be attributed to exceeding the operational temperature of the rubber. Also, notice that Silicone has high rubber temperature resistance and also great low rubber temperature resistance. When we add in temperature, this factor often directs us to the types of materials that can survive the application. As a result, its used extensively with engines, generators, and fuel and hydraulic systems. 285 40 Rubber properties are strongly temperature dependant. Eclipse Engineering. Nitrile Rubber is Ideal for Nitrile pads, Nitrile gasket material, Nitrile seals, Nitrile strips. However, it's less flexible.

Silicone rubber is used in FDA/food processes, high temperatures and where electrical resistance is needed. Nitrile rubber is recommended for applications that require oil and fuel resistance, abrasion resistance, and temperature resistance up to 280 F. In mobile equipment and military vehicles, nitrile seals or gaskets are used in carburetor diaphragms, fuel systems, and hydraulic hoses. 0000008527 00000 n The raw material is typically yellow, although it can also be orange or red tinted, depending on the manufacturer. Other specific UL94 ratings we make bespoke Gaskets for include:UL 94V-0, UL94V-1, UL94HBF, UL94HF-1. The use of elastomers, polymers, carbon, and metal springs are just a few of the tools we use to solve sealing problems. Low Temperatures When rubber is exposed to low temperatures the material changes from rubber-like entropy-elastic to stiff energy-elastic behaviour. |How gasket materials are currently rated and tested for different temperatures. While polymers like Teflon can operate between -400 and 500F, there are many physical changes that cause the material to either be too rigid to seal or have such a large loss of physical properties that it could become useless in an application. Nitrile rubber can be formulated for a modest temperature range of between -25 C and +100 C. Neither should it be used outdoors or where temperatures exceed 200F. |Which specific gasket materials are required for high temperature environments. 0000003017 00000 n The use of metals and compressiblegraphiteare then used to create a seal using materials such asgraphite sheeting(graphitecan be used up to800Cin a non-oxidising atmosphere) orspiral wound gasketsand ring type joints. 11.4 Nitrile Rubber. About NBR. If you are producing consumer, residential and commercial products UL94 is the test rating required. Eclipse Engineering designs seals from the application up. Polar Solvents and Nitrile Rubber Gaskets. A silicone rubber gasket prevents oxygen from penetrating and will resist potential problems, like ozone, UV rays and inclement weather. 0000002940 00000 n ASTM has tests for sponges and foams at 2 different temperatures 158F & 212F. Nitrile Rubber gasket material is a good choice for sealing against fuels, oils, and lubricants. 0000009712 00000 n The requirements for long life are often care in manufacturing the gland with excellent surface finishes. 4749 Tolbut Street, Philadelphia, PA 19136, document.write(new Date().getFullYear()) Stockwell Elastomerics, Inc.

But as temperatures cool, this material becomes less compliant. Privacy Policy, Rubber Temperature Ratings: Ranges for Different Part Materials, Excellent for outdoor applications that require resistance to sunlight, ozone, and weathering, Very cost-effective and versatile in terms of fabrication. Sealing materials are selected for many different reasons. We have sealing applications that exceed 1000F and we often turn to carbon seals like the triple ring seal. |What happens when gaskets are exposed to extreme high and low temperatures. All Rights Reserved. Nitrile is susceptible to attack by polar solvents like those listed above. Off-road equipment. It provides excellent heat and water resistance, performing in temperatures up to 300F/148C. It is a common base for gaskets, O-rings and other types of seals. As an example a door gasket on a NEMA enclosure will compress and rebound as the enclosure heats up and cools off due to thermal expansion. Or need to place an order? The standard temperature range for this material is -40F to 250F. Having a full range of materials allows us to design solutions for your specific needs. This makes them the ideal sealing material for use in engines and other high temperature machinery. Selecting the right gasket material is critical for a reliable joint and effective operation.
