These are accessible in a measure of hardness Products Terms & Conditions Does your sealing application require a gasket material that is resistant to acids, alkalis, gasoline, oil, oxidation and UV? Other alternatives in high temperature (above +500C) are spiral wound gaskets especially when combined with a high pressure environment. The projects that we have worked on include: the light stick sculpture on the M5, the Paris Metro, the media centre at Lords cricket ground, the channel tunnel, and a Mars Lander prototype. Its important to balance both heat resistance and other performance capabilities to invest in quality gaskets. Neoprene can withstand temperatures ranging from -20 degrees F to 180 degrees F. Tensile strength ranges from 900 to 1,000 PSI. High Temperatures - when exposed to extreme high temperatures rubber gaskets are flammable and will ignite. The chemical inertness of closed cell Neoprene makes this material suitable for many industrial and flexible sealing applications, such as gaskets used in electrical enclosures and weather stripping. resistance to petroleum products as well as compression set, tear and Rubber Fabs first product that went to market was the Smart Gasket and the business has been growing ever since! Do you need custom prototypes to prove your theory? The chart below will help you to determine which material has the best possible chance of sustaining your temperature range within your environment. What is waterjet cutting? inertia and is appreciated for non-marking, high abrasion resistance, Selecting the right gasket material is critical for a reliable joint and effective operation. However, these materials are rather costly specialty products used where chemicals and fuels are present. If very low temperatures are required, silicone or fluorosilicone would be the best choice.

They do not therefore constitute a specification. At present time, acrylics have provided an alternative to cashmere that is used in making clothing. depending on grade). BSI Group British Standard Institution have since 1901 covered UK standards, initially within engineering the BSI group is now operating in 172 countries and manages standards and certification to ensure standard quality and manufacture of parts and products across many sectors. This means the gasket material maintains its mechanical properties and will continue to perform as designed without reversion. Industry We Serve | As you can see, its popular because it is resistant to many types ofdamages. You would have less compression using graphite or mica gaskets as they are rigid in nature (than a rubber or other compressible polymer). In applications involving consistent temperatures at 150 F, this elastomer is able to maintain high performance. Search our Gasket Material Specification Sheets to find the right material for you. UL - Underwriters Laboratories is an American worldwide safety consulting and certification company. Surviving a heat aging test only tells part of the story.

Gaskets have to comply with specifications when the complete unit has to undergo testing. JIS - Japanese Industrial Standards specifies the standards used for industrial activities in Japan. As the pressure increases then theCNAF(Compressed Non-Asbestos Fibre) materials will work well up to+450C. Rubbers are generally used above a rigid glass state but the minimum temperature limit is not defined precisely. The closed cell structure of our Neoprene, which creates a water / air tight seal, enables its use in a large number of electrical applications. If the heat is very high (above +500C) a gasket that does not contain rubber such as a graphite or mica is the best option. High temperature is a relative term as it pertains to gaskets and seals. We supply UL rated materials in the form of silicone, silicone foam, neoprene, neoprene foam and poron (urethane).
